Help with aspect ratio on wide screen

[eleven]

For the last while I've had an HP 22' Wide Screen monitor. I still play a few games that don't support the 16:10 resolution, so I need to be able to run them in their native 4:3 resolution. Problem is with my graphics card, a nVidia GeForce 9800GT 512MB, I only have the option "Use my Displays built-in scaling". In order to run in the 4:3, I need to be able to choose one of the other three, but their grayed out.

Up until now I've been running in Windowed mode, but this has become an annoyance.
What I really need is to be able to run in "Do Not Scale" mode.

If any one has any idea in how to change it, please let me know.

My System Specs:

Windows Vista Home Premium 64-Bit
Intel Core 2 Quad Core Processor Q9300
8GB System Memory
750GB 7200RPM Serial ATA Hard Drive
SuperMulti DVD Burner with LightScribe Technology
NVIDIA GeForce 9800GT 512MB

Try running at your native resolution, that may be why the other options are not available. Also try updating the video drivers.

I updated my drivers, changed to my native resolution, and neither worked. Any other ideas?

No, sorry. I had the other options grayed out at one time as well. When I updated my driver they became available again.

Hopefully someone else will pop in with an idea.

Thanks anyway, you tried. :)
