    I just installed a 42" Panasonic plasma in our conference room for our conference room machine to run , and the quality of the combination seems pretty crappy. I'm hoping that I just need to do some tweaking, so I'll present what I have done to you guys to see what you think.

    Dell dimension pc with a nvidia digital pci card installed.. 128mb of video memory, latest driver for the card for XP. Dvi-out of the card to hdmi-in on the plasma using an overpriced radio shack cable.

    When I set the display properties to 1920 x 1080 the image fills the screen properly (I do have to adjust for overscan), but the screen fonts just never become readable. The set acts like the refresh rate isn't set properly, but the only option I have is 60hz.

    Any ideas? My first thought is that I didn't choose my video card well, so I'm certainly willing to return that if that will solve my issue.

    Is the native resolution of the plasma 1920x1080? If not, you should set the output resolution as closely as possible to the native res of the plasma. You should be able to do that directly with the later versions of the nvidia drivers. If not, you may have to use Powerstrip to do it.

    Can you set the display properties lower,, say to 1024 x 768 and see how the fonts work. It may not fill your screen but if the fonts look okay,, it may be that the card cant handle that high of a resolution. Do you know the model of the card ?

    Everything was garbled at lower resolutions. That said, I'm not 100% sure I like the nvidia card. this is an e-geforce fx 5200.. looks like evga makes the card.

    I was looking at spec sheet. It says the highest DVI output is only 1600 x 1200 for that card.

    Powerstrip is a program that lets you define custom output resolutions.
