I have an 22″ Acer AL2251W monitor on my Dell running Windows XP Pro with an Intel 82915G/GV/910GL Video card.

Well every time I reboot this computer, the monitor displays an annoying “Not Supported Resolution” box over Windows.

I finally figured out that by just swapping the display mode back and forth from 1680 x 1050 True Color and High Color, after a few tries, the warning box would go away.

Now that process was downright annoying so today I found an easier solution.

I found ResSwitch which is a command line utility for changing your resolution. So that, coupled with this simple batch file:

@echo off
REM high
resswitch.exe 1680 1050 16 0
REM true
resswitch.exe 1680 1050 32 0

(where 1680 is the width, 1050 is the height, 16 is High color and 32 is True color) all I need to do is keep running the batch file until the box goes away saving several mouse clicks.
