When I turned on my computer, the icons were all enlarged and when I checked the resolution, it had gone down to 1280 x 720. I usually have it at 1440 x 900. When I right click on the desktop and check the res, The maximum it will let me set is 1280 x 720. I updated the driver on my GeForce 9800 GT and still can't raise it. The computer and all its parts are only 1 1/2 yrs old. Could the card be bad? Any help would be appreciated.

Oh, and I restored to a Ghost image from December to see if that would do anything. No change, which kinda leads me to believe it's a hardware thing.

Where are you making the adjustments of the screen resolution, is it the nvidia control panel or through the desktop properties settings?

In the desktop properties. I can't seem to be able to find the NVidia control panel.

Thanks for your reply. :thumbup2:

If you navigate to the Windows 'control panel' and have the control panel set to show all the icons contained in it (in other words, when you open control panel in Windows 7, you will see a drop down menu to the right hand side of the window, this menu has three choices to choose from, by category, small icons or large icons, choose either large or small icons, now you should see a Nvidia control panel icon listed alphabetically in the list of shortcuts that are now visible) Please double click this Nvidia icon, once the Nvidia control panel appears, there should be options listed in the control panel's menu for adjusting the various screen settings.

Look for screen resolution, try making the adjustments here to the one your interested in setting it to.

If you still can not go to the higher settings, please be advised, Windows 7 has a setting that prevents screen resolutions that your monitor does not support from being available in the slider bar for screen resolutions.

To change this, right click your desktop, choose screen resolution, look for ADVANCED SETTINGS, click ADVANCE SETTINGS, look for the MONITOR tab, click MONITOR tab, look for a check mark in a box where it states Hide modes this monitor can not display Once that check mark is removed, your slider bar should now show more screen resolutions.

If you are lost as to where that check mark is located, I will be happy to post a screen shot of its location.

Bruce.

I went out and got a new HD 6670 card and tried to install it. The computer booted up but the monitor said "no signal". I reinstalled my old 9800 GT and it worked. The tech guy on the phone from Micro Center where I got the card said maybe the card was too much for my power supply. I don't think so. I unplugged all my case fans except 1 on my H50 cooler and only have 1 hard drive plugged in. My OCZ 700 psu should be able to easily handle this setup and I checked the voltages with a psu tester. They were fine, It's not like the HD 6670 is a high end power hungry card. It doesn't have an extra power plug. That was my first thought. If it wasn't 30 miles 1 way I would have returned the card.
