Stuck a 25 inch HP monitor on Dell 5150 with Intel Graphics adaptor using VGA. The required resoulution is 1920x1080. It will work but a message appears on the monitor input signal out of range set to 1920X1080 60Hz which is what I have current. Then the monitor goes to sleep after few minutes. Any other resolution I try in windows does not cut it. I uninstalled the adaptor,reboot and I get a 640x480 to work until the OS finds the drivers for the installed adaptors. This is XP PRO.
