Display screen fault repair
May 24, 2018

It is usually because the display does not support the display mode sent by the host, which is often higher than the display mode of the display, causing the screen image to be confusing and unable to see the image and text on the screen. If it is a monitor with automatic mode recognition, it may be a black screen, but the indicator light in the bottom of the panel is green. At this time you can restart the computer into safe mode, change the display mode to 640*480, and then start the computer again to restore. If this method does not work, you can remove the graphics driver in safe mode, and then reinstall the graphics driver in normal mode. There is also a fixed position on the screen that appears to be garbled when the video card's video memory is faulty, but it appears normal in other places. There are also individual video card corruption caused by Huaping, but this situation is very small.
