So I was playing Minecraft and had to quit to finish a document. Suddenly, MS word screen became too red and then everything else was red. My desktop, windows, images everything was too red. I switched off the monitor and turned it back on.-then it was normal again for 2 seconds and Now even after a day of not turning on, once the windows boots up, my screen is red. The thing is, it does not display green color, so everything looks too red or too blue( mostly too red).
I thought it was a problem with my monitor (which is an old CRT and please don't joke) but when I click the button on the side of the monitor that you use to change monitor settings like contrast and brightness, THAT MENU had all the colors perfectly. But still the background (windows desktop screen) was red. So it can't be a problem with my monitor, right? It displays all the colors in monitor settings menu, But no green in windows. I don't know, but I guess the monitor does not need the PC's vga card to display the built in monitor settings menu. Thats why it shows all the colors and windows desktop shows no green. A problem with my Graphics card? How can I fix it?
