So my old card (8800GTS 512) died and I replaced it with a EVGA GT750 (2gb DDR5 128bit). Let me provide a little info.

This setup worked perfectly previously. One screen is a 19" LG LCD TV, 1440x900 connected with a DVI to HDMI cable (TV has no DVI). Other screen is a 50" Panasonic plasma. The only change here other than the new card, is that the 50" is hooked up with HDMI now (in 1080p) rather than component video cable (and 1080i) it had before.

Everything is set to its native resolution @ 60hz

When I first installed the card, It set the smaller monitor to 800x600. and everything had that funny bad low-res look windows has before you've installed drivers. With the newest drivers installed, and with the smaller monitor set to 1440x900, it still LOOKS low res, like it did before I installed the drivers. Colors are a bit weird and text has hazy outlines (banding?)

I have verified it's not a problem with the TV's settings (it was fine before and hadn't been adjusted). For the sake of science, I messed with the picture controls, reset everything to default,AND did the "auto adjust" option, and none of it was the solution.

Here's a video! :)

Any idea what's afoot here? The closest thing I've found to a solution is an outdated article about reinstalling drivers and hacking a registry entry with your monitors EDID, but what's funny is that Nvidia's control panel actually recognizes both monitors and lists them by their brand name (if that matters).

I'd like to think that I've provided enough info to rule out user error. ;)

Thanks!

In my experience, 1440x900 is pretty standard for 19", and as I mentioned, both TVs are set to their native resolution, and nothing has changed but the card. :)

Here's the actual TV I own:

can you confirm on the monitor that its at 900p? It looks more like it accepting the signal but displaying it at a lower resolution.
Just curious, if you plug the HDMI from the card to this TV, is it correctly displaying 900p and not blurry? (single display)
In theory, DVI and HDMI should be more or less fully compatible. Try an newer cable/adapter?

I have never converted a dvi->hdmi so im not sure what options are in the nVidia Control Panel. In theory, it should show the correct TV info in the Adjust desktop size and position section.

The smaller TV has no info button or anything to tell what resolution it's in or what's being sent to it.

As you suggested, I tried pulling it directly from the back of the 1080p TV and hooking the HDMI from the card directly to the smaller TV, and it recognized it immediately as the LG and displayed in crappyvision and 1440x900, w/o me even having to switch the resolution. (I did mention previously that the Nvidia control panel recognizes and gives the brand names for both TVs). There should be nothing wrong with the cable. It's not subjected to any strain, and simply got unplugged from the old card when it died, and plugged into the new. It was never even moved.

I then tried hooking my PS3 to the smaller TV via HDMI, and it looks normal/fine, as far as I can tell.

I also tried changing the dpi setting from 100 to 125% in Windows, but that didn't help either, and just gave me big stupid icons. LOL

This article appears to be describing the problem perfectly, unfortunately, it's for linux. :

there is info about editing EDID info in windows online. I did a simple google search. You can experiment, but it a bit over my head without a full reading of all the info there.
Sorry. Hope someone else has some input on this.
