What should I do if the player plays a movie or TV show card?

First of all, you are sure it is not the player or the machine system software. Then open the case and clean the dust! Or reinstall the graphics card driver!

Furthermore, it may be a problem with the graphics card of your machine itself! Fix it when you have time! If you don't have time, I'll teach you how to use this method first:-Right-click the desktop, click Properties, click Settings in the upper right corner, click Advanced in the lower right corner, click Troubleshooting in the middle of the upper row, pull hardware acceleration to the left, and then click OK! ! So you can watch the video file first! ! !

But if you want to play games or something, you need to pull it back to the right!

I suggest you repair it as a whole! Probably the graphics card itself! Take down the graphics card and try another machine! The graphics card is broken, get it repaired quickly!
