Why can't the refresh rate of Mi 2K Gaming Monitor 27 reach 165Hz when connected to a laptop?

The high refresh rate of a monitor offers several benefits, including smoother visuals, reduced motion blur, and improved responsiveness, especially for fast-paced activities like gaming. The Mi 2K Gaming Monitor 27 has a maximum refresh rate of 165Hz, which is tested under laboratory conditions.
If the Mi 2K Gaming Monitor 27 does not reach 165Hz when connected to a laptop, several factors could affect the refresh rate:
1. Cable and port compatibility: Make sure to use a DisplayPort 1.4 or higher, as the Mi 2K Gaming Monitor 27 requires a DP 1.4 port or an HDMI 2.0 or higher cable to support 165Hz at 2K resolution;
2. System and display settings: In Windows [Display Settings] >> [Advanced display settings], confirm that the refresh rate is correctly set to 165Hz;
3. Graphics card performance and driver: If the GPU cannot maintain a high frame rate at 2K resolution, the refresh rate can fluctuate or even lock at a lower value (such as 144Hz or 120Hz).
For most gamers, a 120Hz to 144Hz refresh rate offers a smooth experience, while 165Hz to 240Hz suits e-sports enthusiasts, and 60Hz is fine for simpler games but not ideal for fast-action or competitive games.
If your monitor is stuck at 60Hz or lower, or 165Hz is not selectable, please refer to the following steps:
1. Verify your cable and port compatibility;
2. Check Windows and in-game display settings;
3. Update the monitor and graphics card drivers;
4. Test the monitor on another device to rule out hardware limitations.
If the issue persists, contact after-sales support for inspection.
