My PC monitor used to have 32-bit color quality at 1024×768 pixels. Then one time, the screen appeared to be bleeding. Large red globs rained down on the screen. After that, the best I could get was 800×600 resolution and 16-bit color.”

This is not unusual to get such type of problem. I also faced such a problem when I installed a new game on my desktop. After I launched the game, the display resolution was degraded and remained like that.

Why display resolution gets affected ?

The most common reason for display resolution reduction / degradation is corruption of display driver files by some application or game. Sometimes drivers may get corrupt due to a corruption of drive area which stores the drivers.


Lets see how to fix it.


Fix is rather simple, just un-install the previously installed display driver / graphics card driver and install it again. Make sure that you have latest version of display drivers / graphic drivers available. Also update the DirectX version for better graphics experience.

Also you can see this post relating to graphics problem for reference.

After you have installed the drivers, restart your computer. The trouble is fixed.

Is it possible to continue after unstalling the present display driver? I’m afraid to try as the screen display might be in a mess then.

If the display resolution is already messed up, then there is no harm taking the risk to un-install the present driver. Restart the computer after un-install and then install the driver again.
