I have an asus motherboard which uses the G33/G31 Express Chip set family video adapter. The computer is connected to an samsungsyncmaster732nw monitor which has a native resolution of 1440 x 900.Everything was running okay until I turned my computer on today and found that the resolution has reset itself to 1280 x 768, and the 1440x 900 resolution is not even listed anymore! This has happened without there being any changes to the system (hardware or software). I have installed the latest Intel drivers for the G33/G31 but this has not resolved the issue. I found a utility on the internet that allows youth check if the monitor's available resolution are 'being seen' by the computer, and sure enough, 1440 x 900 is listed there - so this isn't a problem with the computer recognizing the monitor. I've also installed some other drivers from Intel which are supposed to ensure 1440 x 900support, but these haven't worked either. The really annoying this is that I know my video card is capable of 1440 x 900 resolution because it has been set that way for the last four months! Has anybody any idea what the problem might be?

I would recommend that you go into Device Manager, then locate your Display Adapter, and uninstall it completely. Once it's completely uninstalled, reboot your computer. When it comes back up, it should start out around 800x600, then Windows will attempt to install the default Intel driver. When it does this, it may restore your driver to the original state. Good luck!
Does the Intel software have some kind of control panel? That might have an option to fix just that. For example the software with ATi cards has a Force resolution button, that lets you change the resolution to any the graphics card is capable of, without taking the display into account.
If that option isn't available try reinstalling the graphics driver. If you need any help with that you know where to find me.
