Windows 7 says HP LCD is 'Generic Non-PnP Monitor', low resolution

I recently purchased a Pavilion P7-1108P with Windows 7 (64) to use with a brand new HP S2031 LCD monitor for my home-based accounting business. The Pavilion has an AMD A4-3400 APU with Radeon HD Graphics. There is no VGA port on the back of the computer, only two DVI-D ports. I connected the new monitor to the new computer with the single-link DVI cord that came with the hardware. My problem is with the display; it is huge and pixelated and will not work with the accounting software that I need to use. On the screen resolution page, the display is listed as '1. Generic Non-PnP Monitor' with no other choices available, and the resolution is set at 640 x 480 and greyed out with no other options. I have tried installing the drivers on the CD that came with the monitor, but nothing changes. I have also downloaded the drivers from the HP website for this monitor for Windows 7, but the computer says that it was not installed correctly. After three hours on the phone with HP Tech Support, I was told that the monitor was not compatible with the computer. I did my homework before the purchase, the specs for this monitor state that it is compatible with Windows 7, so what am I missing? Any help would be greatly appreciated... I quit my full-time job to start this business 4 weeks ago, and I need to get up and running ASAP!

Thanks in advance!

Just passing by.

Have you re-installed the Radeon drivers?

I'm not quite sure how to reinstall them... the computer shows that the drivers are up to date, is there another way?

Thanks so much for your help!

Did the monitor come with a driver CD?
If so, did you install it?

Here's my question. When I had XP, I could choose from a wide selection of resolutions as to how I wanted to access my display (I actually have an old but large CRT). It supports many different resolutions and I picked one to maximize real estate - 1600 x 1200 or something around that. However, when I switched to Win 7, I get Generic UPnP and have only 1280x720, 1024x768, and 800x600. I'm forced to use 1024x768.
Can someone explain why for me?
Thanks.
