I have a pretty cheap monitor. It's rated maximum display resolution is 1280x1024 at 60Hz. Normally, I ran it at 1280x960 at 70Hz. Just recently, I unchecked "Hide modes this monitor cannot display", and have been running at a resolution of 1600x900, with a refresh rate of 70Hz. Everything displays correctly, and by adjusting the monitor controls, I could get everything working right. If I try to switch to a higher resolution, the monitor blanks out like normal, but stays blank, then all the lights blink, then Windows reverts to the previous resolution. So I guess running at this resolution isn't causing any short term damage, because Windows would let me switch to it... how about long term damage? Like I said, it's a pretty cheap monitor, so I may replace it in 2 1/2 years or so. By running at a resolution, am I significantly shortening it's life? Will it last 2 years? If I switch the refresh rate lower, to 60Hz, will I lengthen the life of the monitor? Or should I just switch back to 1280x960?
