2. Q: What are the specifications of the Mi Smart Compact Projector?
Note: ① ANSI lumens is a method developed by the American national institute for standardization to measure the luminous flux of projectors. Specific test methods as follows: 1) Distance between the projector and the screen: 2.4 meters. 2) Screen is 60 inches long. 3) Measure the illuminance of each point on the nine intersecting points of the screen "field" glyph shape with a metering pen, multiply by the area, and get the brightness of the nine points of the projected screen. 4) Figure out the average brightness of 9 points, which is ANSI lumens. There may be different test results due to different test conditions.500ANSI lumens are the values measured in the lab highlighting mode. ② Circumstance temperature refers to the maximum decibel value measured by lab when the temperature is 25 ℃ and the distance is 1 meter from the Mi Smart Compact Projector. 3. Q: The appearance of Mi Smart Compact Projector A: As shown
Hot air will be discharged from the cooling hole. Do not place thermosensitive objects near it. Do not place anything around the left and right vents, or it may cause heat to build up inside the projector. The projector gives off strong light when it is working.Do not look directly into the lens to avoid damaging your eyes. The project does not contain the infrared human body detection function, that is: when the human body is approaching, it will not actively reduce the brightness of the light, and the warning words "please do not look directly at the light source" will not pop up. 4. Q: What is the meaning of the 4-channel LED? A: Compared with the traditional three-way LED projection, a blue light path is added, the brightness is increased by more than 20%, and the average brightness reaches 500ANSI lumens (highlight mode). Using Osram LED, NTSC color gamut range up to more than 85%, a wider color gamut to bring more real colors. Hardware related 1. Q: What are the interfaces behind the projector?
1) Power interface 2) Audio out: connect the headphones (3.5mm American standard) 3) USB interface, support USB 3.0 communication protocol 4) HDMI signal input interface (ARC is not supported) 2. Q: Does the projector standard remote control support somatosensory function? A: No. 3. Q: Does projector support infrared remote control? A: No. 4. Q: What is the configuration of projector speaker? A: Full-frequency horn ×2 (total output power (2*5W)≈10W) 5. Q: What is a projection ratio? A: The projection ratio is the ratio of the distance of the lens from the wall to the width of the projected picture.The smaller the projection ratio, the larger the picture at the same distance.For example, to get a 100-inch image, a projection ratio of 1.2 requires a distance of approximately 267cm from the lens to the wall. 6. Q: What is the brightness of the projector? A: The projector brightness up to 500 ANSI lumens. Note: ① ANSI lumens is a method developed by the American national institute for standardization to measure the luminous flux of projectors. Specific test methods as follows: 1) Distance between the projector and the screen: 2.4 meters. 2) Screen is 60 inches long. 3) Measure the illuminance of each point on the nine intersecting points of the screen "field" glyph shape with a metering pen, multiply by the area, and get the brightness of the nine points of the projected screen. 4) Figure out the average brightness of 9 points, which is ANSI lumens. There may be different test results due to different test conditions.500ANSI lumens are the values measured in the lab highlighting mode. 7. Q: What are the standard ? A: Machine body, mi bluetooth voice remote control and battery (Two No. 7 batteries), adapter and instruction manual.
8. Q: How loud is the noise of the projector? Will it affect watching movie at night? A: The maximum noise in the movie viewing mode should not exceed 32db, and the maximum noise in the highlight mode should not exceed 33db. At night, you can choose the movie viewing mode. In the movie viewing mode, the fan noise will be lower, the brightness will be lower, and the eyes can be better protected. 9. Q: Does projector have temperature control function? A: Mi Smart Compact Projector has intelligent temperature control function, LED light source and motherboard temperature by the system monitoring, according to the LED light source and motherboard temperature sensor temperature detected automatically adjust the fan speed.When the projector temperature is too high, the warning popover will pop up automatically. Once the temperature ceiling is reached, the popover window with abnormal temperature will automatically pop out and shut down. If the temperature is too high, the popover will automatically shut down. Check whether there are obstacles blocking the air inlet and outlet.After removing the obstacle, ensure the airflow is unimpeded. After the projector is cooled, it can be normally used after restarting. 10. Q: How about projector overheat? A: The LED light source will generate a lot of heat when the projector is in use. By virtue of the excellent design of air duct in the body, heat dissipation will be faster, and the temperature of the chip during operation will be below 75℃ (the temperature is the highest temperature when the chip is operating, and the actual temperature perceived by the human body will be much lower than this value). When the chip temperature is close to 75 ℃, the system will shut down automatically to ensure the projector, which will be damaged due to high temperature. Please note during use: Ensure the heat dissipation in the right inlet and the left outlet do not have shielding, so as to avoid the machine temperature too high into the temperature protection.Please do not place any object within the distance of 20cm from the cooling port of the projector, so as not to affect the cooling effect.Please unpack the projector before use, so as not to affect the projection effect, air intake and heat dissipation. 11.
