My monitor no longer displays the color red. The first time it happened, and after trying various video tweaks, I replaced the monitor and the problem was gone. Now that it's happened again, I do not know what to think. Is it possible that there could be something wrong with my computer / gpu that causes monitors to no longer be able to display red? In other words, breaks or burns out the monitor itself? Or is this most likely a software or driver issue? It is an old computer running WinXP Pro. Not sure of the specs at the moment. 

Please help. 

I did not find the right solution from the Internet.
