Strange resolution problem with HDTV

Kaiser4149

I got married a few months ago, and rather than hook up my computer to my old 19 inch monitor, I thought that I would try and see if I could get my new wife to agree to letting me hook it up to her 42 inch HDTV. Somehow, I managed to do this. She's a wonderful woman.

Anyways, I have the computer hooked to the TV with a DVI to HDMI cable. When ever I try to set the resolution to 1920 X 1080, things go a little strange. It presents the width of the resolution just fine. It's the height that's the problem. It seems to be twice as tall as it should. It looks more like 1920 X 2160. Whenever I get to the bottom of the screen, it begins to scroll down to show the other half of the resolution not on the screen. I've tried setting the resolution to 1920 X 540, but that looks like crap and will only display in 16 bit color. No way I'm using that. I've got it displaying 1280 X 720 just fine.

Oh, and here's the real weird part. It displays 1920 X 1080 just fine in Ubuntu.:P

Any suggestions?

The HDTV is a ProScan(made by RCA) 42la45h.
My video card is a GeForce FX 5500.

HDTV might only support 1080i, not progressive. Adding a custom interlaced resolution is easy with Nvidia drivers. Right click desktop and go to Nvidia Control Panel. Go to Add Custom resolution and add 1920x1080 and check interlaced. You might need to use the control panel to switch resolution as well.

I've tried that. It still seems to bring up the extra long resolution.

Try the monitor's native res, or stick with Ubuntu??

I had a problem like this, go in the TV's menu and you should have an option for the aspect ratio. Switch it around to see if you get one that works. For me, the option called "just scan" fits perfectly without stretching or compromising the image in any way I can see.

The TV is native 1080p, so it should accept that resolution just fine. No ideas... just wanted to point out that "try the native res" doesn't seem to work.
