May computer was giving me an error that explained my computer display was not operating at proper level. I tried to adjust color diplay settings and it would not allow me to adjust anything. A few days later my son told me the display got stuck and then just stopped working. I turned on the computer today and the monitor did not work. I went and bought another monitor and I received a display. the error is back and I cannot adjust the color quality higher than 4 bit? Is there somehting wrong with my video adapter? would this cause the monitor to fry? Please advise.
