Question: When playing 3D games on a large LCD screen, there is a clear picture with smear, and it feels very smooth. How can I solve this problem?
Answer: This is because the characteristics of the LCD cannot be solved. Due to the longer response time of the LCD, running some 3D games (such as Quake3, etc.) will be more obvious smearing. However, this phenomenon has a shorter response. The time is not significant on the LCD.
Question: What is the size of the light spot of your thumb on the LCD screen?

Q: Can LCD work continuously for a long time?
Answer: LCD is no problem in the long run. In fact, compared with ordinary CRT monitors, LCD monitors have low heat dissipation, low power consumption, and are more suitable for long-term operation, but from the perspective of maintenance, LCD should be given "rest" time.

LCD advertising player manufacturers suggest first to check whether there is magnetic interference around; please check whether the power supply voltage is stable; please check the display and graphics card driver; improve the refresh rate of 75HZ; if it still does not work, you can only find the advertising player manufacturer to fix it.
2. The screen does not appear, and the indicator light on the front panel is shining
Check whether the signal line connection between the display and the microcomputer is strong, and check whether there are broken pins or twists in the connector of the signal line.
3. When the LCD is switched on and off, there are disturbing patterns on the screen
This situation is caused by the signal disturbance of the display card and is attributed to the normal appearance. This question can be resolved by adjusting the phase automatically or manually.
4. There are thumb-sized black spots on the LCD screen
This situation is largely caused by external force pressing. Under the pressure of external force, the polarizer in the LCD panel will be deformed. This polarizer is like aluminum foil and will not bounce up after being recessed. This creates a difference in the reflection of light on the LCD panel, which will show what you see Dim, some of this is easy to find under the white screen. Usually the size is more than ten square millimeters, which is the size of the thumb. This will not affect the life of the LCD. Please pay more attention to it in future applications.
