Embarrassingly high end video problems

I’m ashamed to acknowledge how high-end my computing system is, but I’m throwing myself on your wisdom and your mercy…

I had two LCDs hooked up to my nvidia 8800gtx (from Asus), each at 1280×1024, DVI, set in “span” mode so they functioned as one large desktop. It worked fine. Then yesterday I replaced one of the monitors with an Acer AL2223W wide screen. If I connect the Acer via digital, the Windows Display Property box and the Nvidia prop box both say I’ve set it to 1680×1050, the standard widescreen res. But:

1. The display is fuzzy beyond acceptability.

2, The internal sw of the monitor says it’s in fact set to 1600×1200

3. If I set it to 1600×1200 via the Windows Display Property box, it actually sharpens up quite a bit. Not totally, but a lot. Most other resolutions make it fuzzy again.

4. If I attach the Acer via its analog plug, it’s crisp as overdone toast (in the good sense). Analog works.

I returned the first Acer (after talking with their “support” folks – Asus was far more knowledgeable) but I get exactly the same results. I’ve tested the digital cable and it’s fine.

I’m stumped. Any suggestions about what’s going on? [Tags: ]
