HIS HD4670 1Gb Video Card... What Widescreen Monitor?

Hi, all...

I recently installed an HIS 1Gb HD4670 video card in a slightly more than 5-1/2 year old Dimension 4700 desktop, and also installed the display-only drivers for it from the ATI site (this video card has an 8-way channel high-definition audio bus, but I am running Win XP SP 3, and that version of the OS doesn't seem to support the high-definition audio bus: I had a lot of trouble with a messed-up PC when I tried to install those drivers!).

The question is this. I am using a Dell UltraSharp monitor model 1704FPT. The maximum resolution supported that I can see is 1280x1024, and I am running that currently... without problems.

I would like to go to an ultrasharp widescreen (16:9? aspect?) monitor, supporting whatever the usual screen resolution is at 24" wide... 1400x900? Will my video card support this resolution on a widescreen monitor? Also, since my current monitor has speakers mounted on/integrated with it, I would like a widescreen monitor that would have the same arrangement. Assuming my new video card can support a 24" widescreen monitor... does anyone have suggestions for a monitor of that size that would have speakers mounted on/integrated with it? Any advice appreciated!!

Best regards.

Tony
