Edit: Would You Use HDMI Native Res or TV Native Res?

I've run my PC connected to a TV for the last 2 years, and I really enjoy it. However, I'm not sure which resolution to run for optimal results.

Config:

-PC is connected to the Panasonic X3 plasma TV (http://shop.panasonic.com/shop/model/TC-P42X3) via HDMI.
-HDMI signal is 1920 x 1080. 1080p
-TV is 1024 x 768. "1080p"

Details:

Windows 7 and the GPU (GTX 580) both think 1920 x 1080 is the native display resolution, but when thats selected the screens stretched out too far, and I cant see the borders of the desktop due to overscan.

At 1024 x 768 (native) there are massive black borders on all 4 sides. When I resize/scale to this res, it looks a bit distorted.

No standard res will display correctly; I've tried them all, dozens of them. I've also tried all TV and GPU settings. I have to resize/scale a resolution (the GPU will resize/scale any res.) to get it to fit the screen or create a custom res of ~1824 x 1036.

So I don't know if I should run at 1920 x 1080 because Windows 7/the GPU thinks its correct or the TV's actual native res or perhaps somewhere in between. Maybe 1832*1024 for the desktop and ~768p for gaming?

If running at a higher than native TV res can provide more image detail, I'd definitely go that route, otherwise I'd go with native to gain some FPS in games.

I have a ticket in with Nvidia now and, so far, they are shying away from the technical aspects and seem to be of the opinion that if it fits the screen, that's as good as it gets. Any opinions/suggestions are greatly appreciated

Yeah, I typed the wrong resolution of your plasma TV. If it were a LCD TV then the best resolution to use is the native resolution of 1024x768. However, that is standard definition; an aspect ratio of 4:3. I simply do not understand how a plasma TV with a native resolution with an aspect ratio of 4:3 can be used to display images at 16:9 aspect ratio without some type of distortion.

Perhaps you can get better help at a home theater forum like AVS since people there should have more knowledge about plasma TVs. When people discuss displays here at THG it 99.99% of the time dealing with LCD monitors / HDTVs rather than plasma.

Your Plasma TV is not a true HDTV. The native resolution is only 1280x720. I find that to be very weird. The physical dimension of the TV is 16:9 (widescreen), but the native resolution is 4:3 (standard definition). Maybe that's normal for plasma TVs... I dunno... never owned one.

If the non-standard 1824x1036 resolution seems fine to you then just stick with it. I know trying something like that on a LCD monitor / HDTV will result in some distortion.

I finally read a post about a similar setup (http://www.tomshardware.com/forum/57397-4-edit-720p-capable-1920x1080).

Correct me if I'm wrong, but it sounds like I'm best off resizing the desktop from 1920 x 1080 to the tv's native resolution, as it cannot display more than the native 1024 x 768 pixels.

Thanks for the help; I appreciate it. I'll check out the AVS forum as you suggested.

Pretty appalling I was sold an "HDTV" that is technically SD. Wish I had gone 1920 x 1080. Never thought I'd be able to tell the difference between the 2, but I can see what I'm missing every time I look at true 1080.

Nice avatar img btw. I'm a big Slayer fan too (one of my fav. bands).
