I have a Microtek 710s 17" monitor. It is quite old, 3-5 years. A couple days ago, my best guess is it lost its ability to display the color red. When it should be white, it shows a turquoise ish color. I tried the monitor color controls and the red slider value has no affect on the monitors color at all. Any way to fix it? It started when i was using the CPU intensively, but I had used it even more so a few days before.
