I am using a Dell monitor E177FP with a compaq computer running windows 7. Dell computer crashed hard with no warning what so ever. Problem, My screen resolution will change from small to big to really small. I have readjusted the display settings from the control panel. Right clicked on the screen to reset the screen resolution and even rebooted several times, then all of a sudden it displays correctly. Is there a compatability issue or a patch or what? Please help this is driving my eyes crazy. Thanks

You can look here to see if this E177FP is supported by Win7.
Microsoft WINDOWS 7: http://www.microsoft.com/windows/compatibility/windows-7/en-us/Default.aspx?type=Hardware

From what you described, it sounds like PC problem. But look at MSFT website above first.

I hope your monitor does not have bad caps as shown in my pictures here:
