LG 32LC2D Hookup to Computer Issue

I am having a resolution issue with my new LG 32LC3D info Currently it will only display at 1024x768 and will not switch to a wide format. I previously used a Poloroid FLM-323B 32" LCD info which worked great with my computer, would get 1366x768 and the image was sharp. However i ended up returning it twice due to dead pixels and therefore made the switch. I was wondering if someone could give me a hand or direct me to a program that would help fix this mess. I am currently using a GeForce 7800 GS that is currently used via AGP. I am using a HDMI to DVI cord to connect the TV and computer, and i have also tried the VGA connection cord to interlink them. Thanks

Check deep in nVidia's software for an option to force 16:9 output. It's buried pretty deep in ATI's software.

If there's no such option, try 1280x720 or 1360x768. You can use Powerstrip to force it. Do a web search. It's free. Just stay out of the advanced options if you aren't a video engineer.

Ok checked NVidia Software for the 16:9 force, but could not find anything. So i set the resolution to 1280x720, picture comes in good, but the problem is that parts of the desktop are now off the screen. If i move the mouse to where its off, it scrolls the missing area into view. I checked around for an adjustment to resize the viewing area, but had no such luck. I attempted to force the 1280x720 with Powerstrip and had the same issue. I then tried 1366x768 however the picture does the same thing, and is very fuzzy and appears like the screen is vibrating.

Here's the manual for the nVidia classic Control Panel. Page 88 has the instructions. You have to select a few options to force the card to output HDTV resolutions instead of computer resolutions.

When you get to the resolution box, I'd suggest trying 720p and 1080i to see if there's a difference on your TV.

Good luck!

Ok i followed the instructions and set it to 720p. I then set it to Underscan mode and set the Overscan shift to the left since the desktop was panning off the screen again. Now i am at a 1176x648 resolution, so its a touch better, but i am still at odds as to why i can't get 1366x768 when I could with the other HDTV i returned.

I posted the solution in your other topic

[edit] While the fix I mentioned (TV resolution) will make your desktop fill the screen at a near native resolution, I didn't know anything about the HDTV settings in the nvidia drivers which might work better. I'm going to try those when I get home.

I'm having the same problem. Hooking up my 32LC2D to my Radeon X800, I can't bump the resolution above 1024x768. If I try to force it to anything higher, the screen goes blank and says Invalid Format.

Any suggestions? Would like to play in a widescreen res. :cry:

Have you checked the refresh rate to make sure it's at 60Hz on the higher resolutions?

Yeah, the HDTV format the ATI Control Center gave me was 1280x720 60Hz
