Setting up DVI - HDMI

I'm trying to connect a 9800 Pro to a Samsung 32" LCD, but I'm having problems with resolution. Basically, I can achieve the higher resolutions I want, but picture quality is awful and text looks horrible.

I'm running at 1776 x 1000 at the moment, which is a very odd resolution I know, but is the largest I can go with everything on the screen. 1920 x 1080 pushes icons and the taskber off the screen. I'm using the latest Catalyst drivers. All I really want is to get something better than 1368 x 720, but I'm not sure whether it's the computer or the TV stopping me doing it.

The max res on the 32" LCD is 1366x768. The reason that it looks crap is because the TV is downscaling the higher res picture...

Spot on, I cant get my NV card to do 1366x768 so its doing 1280x768 and squiffing it to fit the screen.

What makes you think you need super hi res?

Why is the max resolution 1366x768? My tv is 32" and does 1080i, isnt that 1900x1080?

its probably saying it can accept a 1080i input, but the res of the screen will probably be 1366x768 and it will be downscaling the picture to fit the native resolution of the screen

Yup, that's correct. My RP HDTV is a 720p panel but it accepts a 1080i signal.

Had to go back to VGA anyway, the 9800 Pro kept overheating and rebooting. Put my finger on the heatsink and it was VERY hot. As for super hi-res, I just wanted to make the most of the panel. I use the LCD as a monitor and a TV due to convenience of location. Guess I'll just have to get used to it :)

what i find odd is that selecting 1360 x 768 (through HDMI at the native res of the panel), gives me a dektop roughly a quarter of the size of the screen, right in the centre. Why does the desktop not simply fill the screen, like it does through VGA?

I didn't think Samsungs do 1:1 pixel mapping over DVI/HDMI?

Some of the models do, the slightly older LE series dont :)

That's crap then. Strange how the top resolutions fit the panel. Is there an AGP card that would do the job I want?

what, get a small resolution to display on the telly? no :)
i've got a sammy 32 incher, and it's native resolution is 1366x768. If i set this in the graphics settings, it displays fine, but any higher resolutions than this, and it goes bye bye.

What card are you using?
when I try and setup a custom res on my NV7800 it says its not a vaild res, might try one of my spare ATi cards and see what I can do there, shame if I cant get it to work as the NV is fanless :/

What I'm asking is why VGA gives me a 1368 x 720 resolution which fills the panel, but HDMI won't?

When you bought your TV it probably said "HD Ready". I think the latest marketing term for true 1920 x 1080 without any downscaling is "Full HD"
