Hello,

Windows 7
Dell Quad Core Studio Desktop
Acer X203H monitor

My wife went to use the computer which had been running for several days and when she got on it the resolution was messed up. She went to change the screen resolution and selected the finest one in the list (top of the list) and the monitor immediately displayed "input not support". I can boot up the machine in safe mode. I have changed the resolution but I still get the same problem when booting up in normal mode.

The display adapters per device manager are the integrated Intel® G45/G43 Express Chipset. This same device is listed twice under the display adapters. I am hestitant to delete these in safe mode as we can at least use the computer in safe mode.

I have read that the Acer monitors can only run at 60 Hz. However in safe mode when I go in under screen resolution advanced settings the monitor tab only gives me the Use hardware default setting for the screen refresh rate. I have set the resolution to 800 x 600 and 1024 x 768 in safe and attempted to reboot in normal without any luck.

Thanks,
Dave

Well I guess I am happy to say I can answer my own question. After messing around for 1.5 hours and then posting, I then find an immediate solution.

Here's the simple solution, at bootup I got the machine into the windows boot options screen. On the Dell I had to toggle F2 at startup and then was given the option for "Advanced Options" via the F8 key. On the Advance Options screen I chose the "Enable Low Resolution Video (640 x 480)". Everything booted without issue. I then manually changed the screen resolutin to 1600 x 900.
