Hdmi quality bad

Hello Everybody,

I have used the gigabyte graphics card gv-n96tzl-1gi-nvidia 9600 gt-pci0e-2.0, i have tried to use a 42' hitachi plasma tv through hdmi to hdmi, tried dvi to hdmi, the resolution is good till 1280 * 1024, when i move it further the quality is bad, can anyone guide me a light on this. i even used the geforce gts250 card with 1 gb. still same.

Thanks for same.

Which operating system are you using? Are you using the plasma TV as your sole monitor or are you extending your PC monitor to the plasma TV? Which drivers do you have installed?

You may need to also enable options in your NVidia control panel. Unfortunately I do not have an NVidia card so I cannot find the exact options, but I suggest you poke around in the HDTV settings that are probably there.

What is your TV's max resolution?

It has an HDMI cable so it's either 720p or 1080p. Since the picture is fine @ 1280x1024 we can be sure it's not 720p because the max on 720p is 1280x720, and from that we know it's 1080p (1920x1080).

I should have read the first post more carefully. I was initially given the impression that things started to go sour ar 1280 x 1024, which is of course why I asked what I asked... .

It's plasma tv so you can't really assume it even has 720p or 1080p as native resolution older plasma tv have a bad habbit of being HD ready but not HD.

Excellent point... This Hitachi plasma TV seems to claim "HD1080p" but its maximum resolution is 1280x1080, sneaky. :non: That'd explain why it runs fine at 1280x1024, but not higher. Oh, marketing. :sarcastic:

Actually no, that's not correct, many plasmas have 'odd' resolutions, and that includes 1024x768/720 (instead of a truer 720P resolution) or even 1024x1024 with is on the Hitachi 42HDM70 and other weird resolutions like 1024x1080 on some Hitachi plasmas, which are primarily 1080i. Unlike LCDs they can do alot more dithering for the picture, especially since the response time is so much higher they can do a better job of looking like higher resolution.

We have an older LG one in the small lunchroom that is 800x600 and has 2 HDMI connections, plus a VGA, so it's no guarantee that HDMI= 720/1080p.

We would need to know the model of the plasma he has to speak to what it can and cannot do. By the sound of things it is one with an odd resolution and he's trying to pump out an image that gets dithered which would be fine for movies and TV but not good for text, or even the text/hud in games.

Yes that is correct, as per the previous posts.

Sounds like the TV is 720p. It's still capable of "displaying" resolutions greater than 720p but it'll scale incorrectly, causing a somewhat blurry display.

Well the resolution is right there on the first line 1024x1080, that's as high as it goes and the proper setting, anything else is interpolation.

Why would you change to a 295? At that resolution it's a complete waste.

Exactly, @ 1024x1080 it aint the power of the card that's at issue, heck I'd recommend something with more movie features than more raw power.

Even GT240 would be good... 1024x1080 is really a weird resolution..
For a movie feature card, I don't know nVidia started providing Audio over HDMI... the low end 9400GT is usually used widely by HTPC(Home Theater P.C) builders..

Don't get a GT240, it's overpriced... Get an HD 4350. I'm not sure why you're trying to spend all this money on a card to watch movies at a low resolution with.

Spend the savings on a better TV, or just stick with your current card. You can't go past 1280x1024 and no card will change that; that is the max resolution of your TV.
