1. Check if the connection between the LCD splicing screen and the graphics card is loose. Poor contact may cause the white screen to appear "messy" or "noisy" and become the most common sight.
2. Check if the LCD TV card is overclocked. If the graphics card is overclocked, it usually displays irregular and intermittent horizontal stripes. At this time, the LCD TV should properly reduce the overclocking. Be careful first to reduce the memory frequency.
3. Check the quality of the graphics card. If a screen problem is displayed after replacing the graphics card, and after the first and second strokes are invalid, the specific method is to keep some components that may be electromagnetically interfered away from the graphics device (such as hard disk), and then check whether the screen is invisible. If it is determined that the electromagnetic shielding function of the graphics card has been turned off, the graphics card or independent shielding should be replaced.
4. Check whether the resolution or refresh rate of the LCD TV screen is too high. The resolution of LCD splicing screens is usually lower than that of CRT monitors. If the optimal resolution is exceeded, there may be a screen image.
5. Check whether an incompatible graphics driver is installed. This situation is usually just ignored, because the graphics card driver update speed is getting faster (especially NVIDIA graphics card), some users always can not delay the installation of the latest version of the driver. In fact, some of the latest drivers are beta versions or versions optimized for specific graphics cards or games. Using this kind of driver may sometimes cause screen flickering. Therefore, it is recommended that you try to use the driver certified by Microsoft and use the driver provided by the graphics card manufacturer.
