Xiaomi Curved Gaming Monitor G34WQi FAQ
Overview
1. Q: What is a monitor?
A: A monitor, also known as a display or a screen, is commonly used for computer visual display. It is a tool that takes certain electronic files, transmits them through specific devices, and shows them on a screen, reflecting them for viewing by the human eyes.
2. Q: What interfaces do the common monitors have and how to choose?
A: Common monitor interfaces include VGA, DVI, HDMI, DP, and USB-C (USB Type-C).
1. VGA: Transmits analog signals without audio. Graphics cards and monitors both use digital signals. If you use a VGA interface, the analog and digital signal will be converted twice. Therefore, the VGA interface will lose some data when transmitting, and the display will be fuzzy;
2. DVI: The interface transmits digital signals without audio. DVI interfaces can also be divided into three types. DVI-I can transmit digital and analog signals, DVI-D can transmit digital signals, and DVI-A can only transmit analog signals. The most commonly used interface in the early days was DVI-I;
3. HDMI: High-Definition Multimedia Interface capable of transmitting both video and audio signals. It's widely adopted because the interface is relatively small. Now most devices have this interface. With the continuous improvement of technical specifications, it is currently the mainstream configuration interface in the market. The latest HDMI interface, HDMI 2.1, boasts a bandwidth increase to 48Gbps and supports resolutions up to 4K at 120Hz and 8K at 60Hz. It features high dynamic range imaging (HDR) for optimized scene and frame enhancements, includes the eARC function for advanced audio support, and synchronizes signals for smoother gaming experiences, reducing screen tearing. HDMI 2.1 is backward compatible with HDMI 2.0 and HDMI 1.4, ensuring versatility across various devices and setups;
4. DP (DisplayPort): Similar to HDMI in transmitting video and audio signals, however, it has stronger interference resistance and greater bandwidth. The DisplayPort 2.0 protocol offers a transmission bandwidth of up to 80Gbps, which is 2.5 times that of DP 1.4 and 1.6 times that of HDMI 2.1. It can output single-screen resolutions such as 16K at 60Hz (DSC), 10K at 60Hz without loss, and 4K at 240Hz. Additionally, it supports dual-screen setups at 4K resolution with 144Hz refresh rate without loss of quality;
5. USB-C (Full-Featured): It offers various functionalities including power delivery, data transmission, data transmission + Alt mode, data transmission + Alt mode + PD (Power Delivery), and data transmission + PD. Alt mode refers to specific protocol operations added to the TX1±, RX1±, TX2±, and RX2± interfaces, incorporating SBU1, SBU2, CC1, and CC2. For example, in DP Alt mode, it can implement the DisplayPort protocol to output video signals. This allows a single cable connection to a monitor, simultaneously transmitting data and video signals while providing power to a laptop, achieving a streamlined solution. Due to protocol and hardware support differences, current USB Type-C interface monitors primarily offer the above-mentioned power delivery specifications. 10-18W is generally sufficient for smartphones and Switch devices, 36W-60W can meet the power needs of lightweight laptops like Surface, and 60W-90W is suitable for mainstream laptop power requirements. Products below 60W are not recommended as they are less practical.
3. Q: What are the differences in bandwidth between HDMI 1.4, HDMI 2.0, and HDMI 2.1 interfaces?
A: HDMI 1.4 could already support 4K, however, due to bandwidth limitations, it maxed out at resolutions of 1920 × 1080 pixels and frame rates of 30fps. HDMI 2.0 expanded the bandwidth to 18Gbps, enabling support for resolutions of 1920 × 1080 pixels at 50fps or 60fps.
Other key improvements are as follows:
1. Synchronous transmission of dual video streams to multiple persons on the same screen;
2. Synchronous transmission of multiple audio streams to up to four persons;
3. Support for 21:9 ultra-wide aspect ratio displays;
4. Dynamic synchronization of video and audio streams;
5. CEC extension for better control of consumer electronics through a single control point.
HDMI 2.0 maintains the same cable shape and interface as HDMI 1.X, ensuring perfect backward compatibility. It also supports up to 32 audio channels and a maximum sampling rate of 1536kHz.
HDMI 2.1 supports 4K video playback at 120Hz and 8K video playback at 60Hz, with dynamic HDR, eARC, fast speeds, high bandwidth, Variable Refresh Rate (VRR), and Quick Frame Transport (QFT) features. It ensures smooth playback essential for the future of 8K and 10K video eras.
The new HDMI 2.1 standard now supports resolutions up to 7680 × 4320 pixels at 60Hz and includes 4K resolutions such as true 4K at 4096 × 2160 pixels and 1920 × 1080 pixels. In contrast, HDMI 2.0 specification only supports up to 4K at 60Hz.
The main differences between HDMI 2.0 and 2.1 are as follows:
1. Transmission Speed Difference: HDMI 2.0 has a bandwidth of 18 Gbps, while HDMI 2.1 has a bandwidth of 48 Gbps, significantly increasing transmission speeds. This bandwidth increase allows HDMI 2.1 to transmit more information, supporting higher resolutions and frame rates;
2. Support for New Features: HDMI 2.0 does not support dynamic HDR, whereas HDMI 2.1 does. Dynamic HDR adjusts HDR metadata on a frame-by-frame basis, enhancing picture quality significantly.
HDMI 2.1 also features eARC (enhanced Audio Return Channel), which allows for high-quality uncompressed audio signals to be transmitted through HDMI cables. Additionally, HDMI 2.1 includes Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) capabilities. These features help reduce latency and can potentially eliminate input lag;
3. Resolution difference: HDMI 2.0 supports 4K images at 60fps or 8K images at 30fps. HDMI 2.1 supports 4K images at 120fps, 8K images at 60fps, and can handle resolutions up to 10K.
To be more specific, the new HDMI 2.1 standard now supports 7680 × 4320 pixels at 60Hz and 4K at 120Hz. 4K includes both true 4K at 4096 × 2160 pixels and UHD at 3840 × 2160 pixels, whereas HDMI 2.0 specifications only support up to 4K at 60Hz.
Looking ahead, HDMI 2.1 cables are a more worthwhile choice. Currently, most devices on the market cannot achieve 8K at 30Hz or 8K at 60Hz ultra-high-definition output, and those that can are expensive price.
However, as 8K ultra-high-definition becomes more prevalent in the future, HDMI 2.1 cables will easily handle it, eliminating the hassle of upgrades. Its future-proofing is widely recognized, capable of transmitting future 8K and 10K TVs, providing an even better viewing experience.
4. Q: What are the main specifications of the HDMI interface?
A: The specifications of the HDMI interface are listed below:
5. Q: What is the difference between the DP 1.2 interface and the HDMI 2.1 interface?
A: DisplayPort (DP) offers similar functionality to HDMI. DP 1.2 has a bandwidth of 21.6Gbps, while HDMI 2.1 has a bandwidth of 48Gbps.
6. Q: What are the differences between the DP 1.2 interface and the DP 1.4 interface?
A: The DisplayPort interface mainly has versions 1.4 and 1.2, with the following main differences:
1. Different maximum bandwidths: DP 1.2 video cables have a bandwidth of 21.6Gbps, while DP 1.4 video cables can reach up to 32Gbps;
2. Different output resolutions: DP 1.2 video cables support output up to 4K at 60Hz, whereas DP 1.4 video cables support outputs of 8K at 60Hz and 4K at 120Hz;
3. Different display technologies: DP 1.4 video cables support 10-bit image transmission, and HDR dynamic image transmission, enabling more realistic and well-defined gaming visuals. It also supports technologies like DSC (Display Stream Compression) and FEC (Forward Error Correction) to eliminate screen tearing and stuttering, resulting in clearer and smoother images.
Compared to its predecessor, DP 1.4 video cables have seen a significant increase in bandwidth, supporting higher resolutions, refresh rates, and dynamic HDR displays. They are also backward compatible with DP 1.2. under similar conditions such as cable length and core specifications, DP 1.4 video cables are slightly more expensive than the previous generation. If your gaming devices support DP 1.4 output or if there are future upgrade needs, it is recommended to use DP 1.4 version video cables.
DP video cables primarily use copper core and optical fiber core. Copper core DP cables provide stable transmission, plug-and-play convenience, and high cost-effectiveness, making them popular in the market. However, due to material limitations, copper core DP cables are mainly suitable for short-distance scenarios within 10 meters. Using them in long-distance scenarios can lead to issues such as severe signal attenuation, susceptibility to interference, and poorer image quality, making it difficult to meet high-bandwidth transmission demands.
Optical fiber DP cables incorporate optoelectronic conversion chips, enabling signal transmission at the speed of light with zero latency. They are immune to external electromagnetic interference and can transmit signals over distances exceeding one hundred meters. However, they come at a higher cost.
Note:
Optical fiber DP cables are unidirectional (transmission direction: from the source to the display). When using them, it's important to ensure correct orientation; incorrect connection will result in no display.
7. Q: What are the differences between screen resolutions 1080p, 2K, and 4K?
A: Screen resolution refers to the number of pixels displayed on the screen. A resolution of 1920 × 1080 means there are 1920 pixels horizontally and 1080 pixels vertically. With screens of the same size, higher resolutions result in clearer images.
4K resolution is 3840 × 2160 pixels, also known as UHD;
2K resolution is 2560 × 1440 pixels, also known as QHD;
1080p resolution is 1920 × 1080 pixels, also known as FHD.
8. Q: What does interlaced monitor refresh rate mean?
A: Refresh rate refers to the number of times the electron beam scans the image on the screen. A higher refresh rate results in better stability of the displayed image.
Interlaced refers to a different scanning method. Without interlacing, it's called a progressive scan, where each line is scanned sequentially. With interlacing, odd and even lines are scanned alternately. At the same frame rate, this method reduces visual flicker compared to progressive scanning.
For example, 60Hz means a refresh rate of 60 frames per second. Interlacing means rendering odd and even frames separately, such as rendering odd frames first (60 times per second) and then even frames (60 times per second), completing 120 frames in 2 seconds, known as interlaced scanning. 60Hz with progressive scan means simultaneously rendering odd and even frames, completing 60 frames in 1 second.
9. Q: What is a gaming monitor?
A: Gaming monitors have the following hardware features:
1. High refresh rate: Supports 144Hz and above;
2. Supports variable refresh rate technology: FreeSync (AMD), G-SYNC (NVIDIA);
3. Wide color gamut: Rich and vibrant colors;
4. Gray-to-gray response time: Less than or equal to 5ms.
10. Q: What is the screen refresh rate?
A: Screen refresh rate refers to the number of times the screen refreshes the image per second. Common refresh rates include 60Hz, 120Hz, 144Hz, 165Hz, and 240Hz. The higher the refresh rate, the smoother the display.
11. Q: What is color depth and color gamut?
A: Color depth refers to the number of colors that can be described for each pixel at a specific resolution. It primarily depends on the brightness (luminance) of object colors and is related to hue and saturation, providing an overall sense of color for objects. The bit number indicates the number of colors available. A higher bit depth results in higher screen resolution, reducing visible color banding and creating smoother color transitions. Common color depths are 8-bit and 10-bit.
Color depth differs from color gamut in that color gamut determines which colors can be represented (the visible range of colors), while color depth determines how subtle the transitions and changes between colors can be (NTSC color gamut is larger than sRGB, resulting in richer relative colors).
Color gamut refers to the range of colors a display can show, which can be used to measure how many colors a screen can display. Common color standards include sRGB, Adobe RGB, and P3. Within the same color space, a higher percentage of color gamut indicates a wider range of colors that can be displayed.
Display effects: 45% NTSC < 72% NTSC < 100% sRGB < 100% P3 < 100% Adobe RGB.
sRGB was one of the earliest color gamut standards jointly developed by Microsoft and HP. It has moderate color reproduction accuracy, however, it has a lower coverage of green.
NTSC color gamut was established by the American National Television System Committee. It is commonly used to test the color range that TV screens can cover. The sRGB color gamut range nearly falls within the NTSC color gamut range, covering approximately 72% of NTSC (NTSC does not fully encompass sRGB).
DCI-P3 is a color gamut standard unified for digital cinema industry encoding, serving as the shooting standard for Hollywood movies. Monitors that can cover this color gamut can accurately reproduce all colors intended in movies. Measured against the NTSC standard, 100% DCI-P3 equals approximately 96% NTSC, while sRGB equals about 71% NTSC.
12. Q: What is color accuracy?
A: Color accuracy, or color precision, refers to the accuracy of the colors displayed by a device. It is generally represented by Delta E or ΔE. ΔE measures the deviation of the colors shown on the screen from the true colors, reflecting the accuracy of the display. Therefore, the smaller the value, the less color distortion there is. A lower ΔE indicates better color reproduction, while a higher ΔE suggests greater color distortion. A ΔE between 1.6 and 3.2 is generally considered indistinguishable from the human eyes from a certain distance, whereas non-professional displays have a ΔE between 3.2 and 6.5.
13. Q: What is HDR?
A: High Dynamic Range (HDR) enhances the visualization of images by using a greater range of brightness levels that the human eyes can perceive, from bright whites to deep blacks. This results in a more realistic representation of real-world scenes. Before HDR, only Standard Dynamic Range (SDR) was available. The issue with SDR displays is that the photos displayed on the screen often do not look like the original scene. An SDR display cannot fully show the various colors, bright lights, and ultra-dark shadows visible in the original scene. In contrast, HDR is a technology that can maintain the same average brightness while significantly increasing the color range and boosting contrast by over 100 times.
14. Q: Which version of the Windows operating system supports HDR?
A: To output HDR to an external display, it is recommended to use Windows 10 Redstone 4 (version 1803) or later. For outputting HDR to an integrated display (such as on a laptop or all-in-one PC), Windows 10 Redstone 6 (version 1903) or later is recommended.
You can determine your current Windows version by typing "winver" in the Start button search box or in a command window. If you have an earlier version of Windows 10, you can easily update to the latest version through the Windows Update process. Each new version of Windows improves HDR capabilities, so updating to the current version is advisable.
15. Q: What are the introduction and characteristics comparison of screen materials?
A: Currently, the mainstream screen types are IPS, TN, and VA.
1. Color and color accuracy: IPS > VA > TN;
2. Response time: TN > IPS > VA;
3. Viewing angles: IPS > VA > TN;
4. Contrast ratio: VA > IPS > TN.
In recent years, new technologies like Nano IPS and Fast IPS have emerged. Nano IPS aims to enhance color gamut and color accuracy, while Fast IPS focuses on improving response times.
16. Q: What hardware is needed to run HDR on a Windows PC?
A: You need a compatible graphics processing unit (GPU), an HDR display, and the appropriate cables to connect the PC to the monitor.
17. Q: Which GPUs support HDR?
A: Intel 7th Gen Core processors and higher with integrated graphics, starting from HD 620 graphics, NVIDIA GeForce GTX 10 series/16 series, RTX 20 series graphics cards, and AMD Radeon Rx 5 series and Radeon Rx VEGA graphics all support the HDR10 protocol.
18. Q: Which cable interfaces can be used for HDR?
A: DisplayPort v1.2 and higher, USB-C with DisplayPort Alt mode, Thunderbolt-3, and HDMI v2.0a or v2.1. For laptops or all-in-one PCs (AIO), integrated panels can enable HDR, in which case you don't need to worry about interfaces and cables.
19. Q: How to check if the PC is running in HDR mode?
A: To perform a basic check, right-click on the desktop to open the Display Settings page. Look for an option called Play HDR games and APPs and ensure it is enabled. Scroll down to the bottom of the page and enter the Windows HD Color settings submenu to inspect visible differences between SDR and HDR video images.
For a more detailed confirmation:
1. Check whether you are running the appropriate version of Windows. For external monitors (displays and TVs), you need version 1803 or higher. For integrated panels on laptops or all-in-one PCs, you need version 1903 or higher. Check your Windows version by typing winver in the Start button search or command window. If using an older version of Windows 10, update through the Check for updates process accessed via the Start button or command window, following update instructions;
2. Check whether your GPU has the latest video drivers from Intel, NVIDIA, or AMD;
3. Check whether Windows has enabled HDR mode on the appropriate display. Right-click on a blank area of the desktop, and select Display settings from the popup window. If multiple displays are connected, choose the HDR-capable display. Under the Windows HD Color section, below Display capabilities, select Play HDR games and APPs to enable HDR mode. Check the monitor's on-screen menu to confirm HDR mode is enabled. After adjusting the monitor's on-screen menu, you will need to reset the display or restart the PC.
Note:
If the Play HDR games and APPs button is absent, your PC's GPU can not support HDR, or your PC can not recognize the display as HDR-capable.
20. Q: Which settings are unavailable after enabling HDR?
A: Game mode and image mode options are grayed out and cannot be adjusted. This includes mode selection, brightness, contrast, color temperature, hue, saturation, gamma value, dynamic contrast, clarity, grayscale response time, dark scene intensity, and color space. These settings are disabled due to conflicts with HDR functionality and can only be adjusted after HDR is turned off.
21. Q: What is FreeSync?
A: In high-frame-rate FPS games, screen tearing can often occur, where parts of the screen at the top and bottom seem misaligned, resembling two randomly overlaid images.
Each frame of the image is displayed pixel by pixel from left to right (though it's imperceptible to the human eyes due to speed). This can lead to stuttering when the frame rate generated is significantly lower than the monitor's refresh rate. Matching the refresh rate of the monitor with the output frame rate of the graphics card can perfectly prevent tearing. Vertical sync forces the graphics card to use the monitor's refresh rate as its operating frame rate to achieve a follow the monitor effect (at the cost of sacrificing some frames).
FreeSync monitors enable AMD's graphics cards and APUs (Accelerated Processing Units) to dynamically control the refresh rate of the connected display. Monitors that support FreeSync synchronize with the game's refresh rate, with the upper limit being its maximum refresh rate, which adjusts as necessary.
You can refer to the official AMD website for more details: https://www.amd.com/zh-hans/technologies/free-sync-faq
Note:
FreeSync requires a compatible AMD graphics card or APU system, and the connection cable needs to be a DisplayPort (DP) cable. NVIDIA also supports compatibility with FreeSync monitors.
22. Q: What are the differences among FreeSync, Adaptive-Sync, FreeSync Premium and G-Sync?
A: G-Sync is hardware optimization primarily for NVIDIA graphics cards (NVIDIA GPUs). FreeSync/Adaptive-Sync is primarily software optimization for AMD (Radeon GPUs). FreeSync technology dynamically updates refresh rates via software display ports and is compatible with HDMI and DisplayPort connections. Adaptive-Sync is an extension of FreeSync, requiring a DP1.2 cable and GTX10 series or higher graphics cards. Software requirements include Windows 10 and driver updates to version 417.71 or higher. NVIDIA's GeForce graphics cards are compatible with FreeSync/Adaptive-Sync, with restrictions similar to Adaptive-Sync.

1. Q: What is a monitor?
A: A monitor, also known as a display or a screen, is commonly used for computer visual display. It is a tool that takes certain electronic files, transmits them through specific devices, and shows them on a screen, reflecting them for viewing by the human eyes.
2. Q: What interfaces do the common monitors have and how to choose?
A: Common monitor interfaces include VGA, DVI, HDMI, DP, and USB-C (USB Type-C).
1. VGA: Transmits analog signals without audio. Graphics cards and monitors both use digital signals. If you use a VGA interface, the analog and digital signal will be converted twice. Therefore, the VGA interface will lose some data when transmitting, and the display will be fuzzy;
2. DVI: The interface transmits digital signals without audio. DVI interfaces can also be divided into three types. DVI-I can transmit digital and analog signals, DVI-D can transmit digital signals, and DVI-A can only transmit analog signals. The most commonly used interface in the early days was DVI-I;
3. HDMI: High-Definition Multimedia Interface capable of transmitting both video and audio signals. It's widely adopted because the interface is relatively small. Now most devices have this interface. With the continuous improvement of technical specifications, it is currently the mainstream configuration interface in the market. The latest HDMI interface, HDMI 2.1, boasts a bandwidth increase to 48Gbps and supports resolutions up to 4K at 120Hz and 8K at 60Hz. It features high dynamic range imaging (HDR) for optimized scene and frame enhancements, includes the eARC function for advanced audio support, and synchronizes signals for smoother gaming experiences, reducing screen tearing. HDMI 2.1 is backward compatible with HDMI 2.0 and HDMI 1.4, ensuring versatility across various devices and setups;
4. DP (DisplayPort): Similar to HDMI in transmitting video and audio signals, however, it has stronger interference resistance and greater bandwidth. The DisplayPort 2.0 protocol offers a transmission bandwidth of up to 80Gbps, which is 2.5 times that of DP 1.4 and 1.6 times that of HDMI 2.1. It can output single-screen resolutions such as 16K at 60Hz (DSC), 10K at 60Hz without loss, and 4K at 240Hz. Additionally, it supports dual-screen setups at 4K resolution with 144Hz refresh rate without loss of quality;
5. USB-C (Full-Featured): It offers various functionalities including power delivery, data transmission, data transmission + Alt mode, data transmission + Alt mode + PD (Power Delivery), and data transmission + PD. Alt mode refers to specific protocol operations added to the TX1±, RX1±, TX2±, and RX2± interfaces, incorporating SBU1, SBU2, CC1, and CC2. For example, in DP Alt mode, it can implement the DisplayPort protocol to output video signals. This allows a single cable connection to a monitor, simultaneously transmitting data and video signals while providing power to a laptop, achieving a streamlined solution. Due to protocol and hardware support differences, current USB Type-C interface monitors primarily offer the above-mentioned power delivery specifications. 10-18W is generally sufficient for smartphones and Switch devices, 36W-60W can meet the power needs of lightweight laptops like Surface, and 60W-90W is suitable for mainstream laptop power requirements. Products below 60W are not recommended as they are less practical.
3. Q: What are the differences in bandwidth between HDMI 1.4, HDMI 2.0, and HDMI 2.1 interfaces?
A: HDMI 1.4 could already support 4K, however, due to bandwidth limitations, it maxed out at resolutions of 1920 × 1080 pixels and frame rates of 30fps. HDMI 2.0 expanded the bandwidth to 18Gbps, enabling support for resolutions of 1920 × 1080 pixels at 50fps or 60fps.
Other key improvements are as follows:
1. Synchronous transmission of dual video streams to multiple persons on the same screen;
2. Synchronous transmission of multiple audio streams to up to four persons;
3. Support for 21:9 ultra-wide aspect ratio displays;
4. Dynamic synchronization of video and audio streams;
5. CEC extension for better control of consumer electronics through a single control point.
HDMI 2.0 maintains the same cable shape and interface as HDMI 1.X, ensuring perfect backward compatibility. It also supports up to 32 audio channels and a maximum sampling rate of 1536kHz.
HDMI 2.1 supports 4K video playback at 120Hz and 8K video playback at 60Hz, with dynamic HDR, eARC, fast speeds, high bandwidth, Variable Refresh Rate (VRR), and Quick Frame Transport (QFT) features. It ensures smooth playback essential for the future of 8K and 10K video eras.
The new HDMI 2.1 standard now supports resolutions up to 7680 × 4320 pixels at 60Hz and includes 4K resolutions such as true 4K at 4096 × 2160 pixels and 1920 × 1080 pixels. In contrast, HDMI 2.0 specification only supports up to 4K at 60Hz.
The main differences between HDMI 2.0 and 2.1 are as follows:
1. Transmission Speed Difference: HDMI 2.0 has a bandwidth of 18 Gbps, while HDMI 2.1 has a bandwidth of 48 Gbps, significantly increasing transmission speeds. This bandwidth increase allows HDMI 2.1 to transmit more information, supporting higher resolutions and frame rates;
2. Support for New Features: HDMI 2.0 does not support dynamic HDR, whereas HDMI 2.1 does. Dynamic HDR adjusts HDR metadata on a frame-by-frame basis, enhancing picture quality significantly.
HDMI 2.1 also features eARC (enhanced Audio Return Channel), which allows for high-quality uncompressed audio signals to be transmitted through HDMI cables. Additionally, HDMI 2.1 includes Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) capabilities. These features help reduce latency and can potentially eliminate input lag;
3. Resolution difference: HDMI 2.0 supports 4K images at 60fps or 8K images at 30fps. HDMI 2.1 supports 4K images at 120fps, 8K images at 60fps, and can handle resolutions up to 10K.
To be more specific, the new HDMI 2.1 standard now supports 7680 × 4320 pixels at 60Hz and 4K at 120Hz. 4K includes both true 4K at 4096 × 2160 pixels and UHD at 3840 × 2160 pixels, whereas HDMI 2.0 specifications only support up to 4K at 60Hz.
Looking ahead, HDMI 2.1 cables are a more worthwhile choice. Currently, most devices on the market cannot achieve 8K at 30Hz or 8K at 60Hz ultra-high-definition output, and those that can are expensive price.
However, as 8K ultra-high-definition becomes more prevalent in the future, HDMI 2.1 cables will easily handle it, eliminating the hassle of upgrades. Its future-proofing is widely recognized, capable of transmitting future 8K and 10K TVs, providing an even better viewing experience.

5. Q: What is the difference between the DP 1.2 interface and the HDMI 2.1 interface?
A: DisplayPort (DP) offers similar functionality to HDMI. DP 1.2 has a bandwidth of 21.6Gbps, while HDMI 2.1 has a bandwidth of 48Gbps.
6. Q: What are the differences between the DP 1.2 interface and the DP 1.4 interface?
A: The DisplayPort interface mainly has versions 1.4 and 1.2, with the following main differences:
1. Different maximum bandwidths: DP 1.2 video cables have a bandwidth of 21.6Gbps, while DP 1.4 video cables can reach up to 32Gbps;
2. Different output resolutions: DP 1.2 video cables support output up to 4K at 60Hz, whereas DP 1.4 video cables support outputs of 8K at 60Hz and 4K at 120Hz;
3. Different display technologies: DP 1.4 video cables support 10-bit image transmission, and HDR dynamic image transmission, enabling more realistic and well-defined gaming visuals. It also supports technologies like DSC (Display Stream Compression) and FEC (Forward Error Correction) to eliminate screen tearing and stuttering, resulting in clearer and smoother images.
Compared to its predecessor, DP 1.4 video cables have seen a significant increase in bandwidth, supporting higher resolutions, refresh rates, and dynamic HDR displays. They are also backward compatible with DP 1.2. under similar conditions such as cable length and core specifications, DP 1.4 video cables are slightly more expensive than the previous generation. If your gaming devices support DP 1.4 output or if there are future upgrade needs, it is recommended to use DP 1.4 version video cables.
DP video cables primarily use copper core and optical fiber core. Copper core DP cables provide stable transmission, plug-and-play convenience, and high cost-effectiveness, making them popular in the market. However, due to material limitations, copper core DP cables are mainly suitable for short-distance scenarios within 10 meters. Using them in long-distance scenarios can lead to issues such as severe signal attenuation, susceptibility to interference, and poorer image quality, making it difficult to meet high-bandwidth transmission demands.
Optical fiber DP cables incorporate optoelectronic conversion chips, enabling signal transmission at the speed of light with zero latency. They are immune to external electromagnetic interference and can transmit signals over distances exceeding one hundred meters. However, they come at a higher cost.
Note:
Optical fiber DP cables are unidirectional (transmission direction: from the source to the display). When using them, it's important to ensure correct orientation; incorrect connection will result in no display.
7. Q: What are the differences between screen resolutions 1080p, 2K, and 4K?
A: Screen resolution refers to the number of pixels displayed on the screen. A resolution of 1920 × 1080 means there are 1920 pixels horizontally and 1080 pixels vertically. With screens of the same size, higher resolutions result in clearer images.
4K resolution is 3840 × 2160 pixels, also known as UHD;
2K resolution is 2560 × 1440 pixels, also known as QHD;
1080p resolution is 1920 × 1080 pixels, also known as FHD.
8. Q: What does interlaced monitor refresh rate mean?
A: Refresh rate refers to the number of times the electron beam scans the image on the screen. A higher refresh rate results in better stability of the displayed image.
Interlaced refers to a different scanning method. Without interlacing, it's called a progressive scan, where each line is scanned sequentially. With interlacing, odd and even lines are scanned alternately. At the same frame rate, this method reduces visual flicker compared to progressive scanning.
For example, 60Hz means a refresh rate of 60 frames per second. Interlacing means rendering odd and even frames separately, such as rendering odd frames first (60 times per second) and then even frames (60 times per second), completing 120 frames in 2 seconds, known as interlaced scanning. 60Hz with progressive scan means simultaneously rendering odd and even frames, completing 60 frames in 1 second.
9. Q: What is a gaming monitor?
A: Gaming monitors have the following hardware features:
1. High refresh rate: Supports 144Hz and above;
2. Supports variable refresh rate technology: FreeSync (AMD), G-SYNC (NVIDIA);
3. Wide color gamut: Rich and vibrant colors;
4. Gray-to-gray response time: Less than or equal to 5ms.
10. Q: What is the screen refresh rate?
A: Screen refresh rate refers to the number of times the screen refreshes the image per second. Common refresh rates include 60Hz, 120Hz, 144Hz, 165Hz, and 240Hz. The higher the refresh rate, the smoother the display.
11. Q: What is color depth and color gamut?
A: Color depth refers to the number of colors that can be described for each pixel at a specific resolution. It primarily depends on the brightness (luminance) of object colors and is related to hue and saturation, providing an overall sense of color for objects. The bit number indicates the number of colors available. A higher bit depth results in higher screen resolution, reducing visible color banding and creating smoother color transitions. Common color depths are 8-bit and 10-bit.
Color depth differs from color gamut in that color gamut determines which colors can be represented (the visible range of colors), while color depth determines how subtle the transitions and changes between colors can be (NTSC color gamut is larger than sRGB, resulting in richer relative colors).
Color gamut refers to the range of colors a display can show, which can be used to measure how many colors a screen can display. Common color standards include sRGB, Adobe RGB, and P3. Within the same color space, a higher percentage of color gamut indicates a wider range of colors that can be displayed.
Display effects: 45% NTSC < 72% NTSC < 100% sRGB < 100% P3 < 100% Adobe RGB.
sRGB was one of the earliest color gamut standards jointly developed by Microsoft and HP. It has moderate color reproduction accuracy, however, it has a lower coverage of green.
NTSC color gamut was established by the American National Television System Committee. It is commonly used to test the color range that TV screens can cover. The sRGB color gamut range nearly falls within the NTSC color gamut range, covering approximately 72% of NTSC (NTSC does not fully encompass sRGB).
DCI-P3 is a color gamut standard unified for digital cinema industry encoding, serving as the shooting standard for Hollywood movies. Monitors that can cover this color gamut can accurately reproduce all colors intended in movies. Measured against the NTSC standard, 100% DCI-P3 equals approximately 96% NTSC, while sRGB equals about 71% NTSC.
12. Q: What is color accuracy?
A: Color accuracy, or color precision, refers to the accuracy of the colors displayed by a device. It is generally represented by Delta E or ΔE. ΔE measures the deviation of the colors shown on the screen from the true colors, reflecting the accuracy of the display. Therefore, the smaller the value, the less color distortion there is. A lower ΔE indicates better color reproduction, while a higher ΔE suggests greater color distortion. A ΔE between 1.6 and 3.2 is generally considered indistinguishable from the human eyes from a certain distance, whereas non-professional displays have a ΔE between 3.2 and 6.5.
13. Q: What is HDR?
A: High Dynamic Range (HDR) enhances the visualization of images by using a greater range of brightness levels that the human eyes can perceive, from bright whites to deep blacks. This results in a more realistic representation of real-world scenes. Before HDR, only Standard Dynamic Range (SDR) was available. The issue with SDR displays is that the photos displayed on the screen often do not look like the original scene. An SDR display cannot fully show the various colors, bright lights, and ultra-dark shadows visible in the original scene. In contrast, HDR is a technology that can maintain the same average brightness while significantly increasing the color range and boosting contrast by over 100 times.
14. Q: Which version of the Windows operating system supports HDR?
A: To output HDR to an external display, it is recommended to use Windows 10 Redstone 4 (version 1803) or later. For outputting HDR to an integrated display (such as on a laptop or all-in-one PC), Windows 10 Redstone 6 (version 1903) or later is recommended.
You can determine your current Windows version by typing "winver" in the Start button search box or in a command window. If you have an earlier version of Windows 10, you can easily update to the latest version through the Windows Update process. Each new version of Windows improves HDR capabilities, so updating to the current version is advisable.
15. Q: What are the introduction and characteristics comparison of screen materials?
A: Currently, the mainstream screen types are IPS, TN, and VA.
1. Color and color accuracy: IPS > VA > TN;
2. Response time: TN > IPS > VA;
3. Viewing angles: IPS > VA > TN;
4. Contrast ratio: VA > IPS > TN.
In recent years, new technologies like Nano IPS and Fast IPS have emerged. Nano IPS aims to enhance color gamut and color accuracy, while Fast IPS focuses on improving response times.
16. Q: What hardware is needed to run HDR on a Windows PC?
A: You need a compatible graphics processing unit (GPU), an HDR display, and the appropriate cables to connect the PC to the monitor.
17. Q: Which GPUs support HDR?
A: Intel 7th Gen Core processors and higher with integrated graphics, starting from HD 620 graphics, NVIDIA GeForce GTX 10 series/16 series, RTX 20 series graphics cards, and AMD Radeon Rx 5 series and Radeon Rx VEGA graphics all support the HDR10 protocol.
18. Q: Which cable interfaces can be used for HDR?
A: DisplayPort v1.2 and higher, USB-C with DisplayPort Alt mode, Thunderbolt-3, and HDMI v2.0a or v2.1. For laptops or all-in-one PCs (AIO), integrated panels can enable HDR, in which case you don't need to worry about interfaces and cables.
19. Q: How to check if the PC is running in HDR mode?
A: To perform a basic check, right-click on the desktop to open the Display Settings page. Look for an option called Play HDR games and APPs and ensure it is enabled. Scroll down to the bottom of the page and enter the Windows HD Color settings submenu to inspect visible differences between SDR and HDR video images.
For a more detailed confirmation:
1. Check whether you are running the appropriate version of Windows. For external monitors (displays and TVs), you need version 1803 or higher. For integrated panels on laptops or all-in-one PCs, you need version 1903 or higher. Check your Windows version by typing winver in the Start button search or command window. If using an older version of Windows 10, update through the Check for updates process accessed via the Start button or command window, following update instructions;
2. Check whether your GPU has the latest video drivers from Intel, NVIDIA, or AMD;
3. Check whether Windows has enabled HDR mode on the appropriate display. Right-click on a blank area of the desktop, and select Display settings from the popup window. If multiple displays are connected, choose the HDR-capable display. Under the Windows HD Color section, below Display capabilities, select Play HDR games and APPs to enable HDR mode. Check the monitor's on-screen menu to confirm HDR mode is enabled. After adjusting the monitor's on-screen menu, you will need to reset the display or restart the PC.
Note:
If the Play HDR games and APPs button is absent, your PC's GPU can not support HDR, or your PC can not recognize the display as HDR-capable.
20. Q: Which settings are unavailable after enabling HDR?
A: Game mode and image mode options are grayed out and cannot be adjusted. This includes mode selection, brightness, contrast, color temperature, hue, saturation, gamma value, dynamic contrast, clarity, grayscale response time, dark scene intensity, and color space. These settings are disabled due to conflicts with HDR functionality and can only be adjusted after HDR is turned off.
21. Q: What is FreeSync?
A: In high-frame-rate FPS games, screen tearing can often occur, where parts of the screen at the top and bottom seem misaligned, resembling two randomly overlaid images.
Each frame of the image is displayed pixel by pixel from left to right (though it's imperceptible to the human eyes due to speed). This can lead to stuttering when the frame rate generated is significantly lower than the monitor's refresh rate. Matching the refresh rate of the monitor with the output frame rate of the graphics card can perfectly prevent tearing. Vertical sync forces the graphics card to use the monitor's refresh rate as its operating frame rate to achieve a follow the monitor effect (at the cost of sacrificing some frames).
FreeSync monitors enable AMD's graphics cards and APUs (Accelerated Processing Units) to dynamically control the refresh rate of the connected display. Monitors that support FreeSync synchronize with the game's refresh rate, with the upper limit being its maximum refresh rate, which adjusts as necessary.
You can refer to the official AMD website for more details: https://www.amd.com/zh-hans/technologies/free-sync-faq
Note:
FreeSync requires a compatible AMD graphics card or APU system, and the connection cable needs to be a DisplayPort (DP) cable. NVIDIA also supports compatibility with FreeSync monitors.
22. Q: What are the differences among FreeSync, Adaptive-Sync, FreeSync Premium and G-Sync?
A: G-Sync is hardware optimization primarily for NVIDIA graphics cards (NVIDIA GPUs). FreeSync/Adaptive-Sync is primarily software optimization for AMD (Radeon GPUs). FreeSync technology dynamically updates refresh rates via software display ports and is compatible with HDMI and DisplayPort connections. Adaptive-Sync is an extension of FreeSync, requiring a DP1.2 cable and GTX10 series or higher graphics cards. Software requirements include Windows 10 and driver updates to version 417.71 or higher. NVIDIA's GeForce graphics cards are compatible with FreeSync/Adaptive-Sync, with restrictions similar to Adaptive-Sync.
You can find specific details about the advantages of G-sync here: https://www.nvidia.cn/geforce/products/g-sync-monitors/
You can find specific details about the advantages of FreeSync here: https://www.amd.com/zh-hans/technologies/free-sync-faq#faq-DisplayPort
At CES 2020, AMD redefined its FreeSync certification levels, discontinuing the older FreeSync and FreeSync 2 HDR categories, and introducing new tiers: FreeSync, FreeSync Premium, and FreeSync Premium Pro. FreeSync is the basic level, indicating that the monitor supports tear-free gaming when paired with AMD Radeon graphics cards and using a DisplayPort (DP) interface. FreeSync Premium certification requirements are stricter, requiring monitors to have at least a 120Hz refresh rate, 1080P resolution, and support for Low Framerate Compensation (LFC).
The highest certification level is FreeSync Premium Pro, essentially replacing FreeSync 2 HDR, which mandates HDR support as a mandatory feature.
For more details, you can refer to AMD's FreeSync (Gaming Smart Display) technology:
https://www.amd.com/zh-hans/technologies/free-sync.
23. Q: What is the MPRT?
A: MPRT (Moving Picture Response Time) is a technique to reduce motion blur in images. It involves temporarily turning off the backlight of the screen during color transitions and then turning it back on after the color change to minimize perceived motion blur and ghosting effects. This technique enhances visual smoothness and reduces visual artifacts such as trailing or ghosting in fast-moving scenes.
