I have an ACER LCD monitor with Intel G33/G31 display chipset. The preferred resolution for monitor is 1440x900.
The drivers for both monitor and display are correctly installed and displayed in Device Manager section.
However, I have observed, sometimes, in Display properties, my PC shows
Display Device on: VGA instead of
Display Device on: Acer , and when that happens, the resolution becomes distorted and I am unable to switch back to 1440x900.
However, this problem resolves itself automatically sometimes between reboots.
Any idea what's going on ?
