Don't be discouraged by hdtv's rant, you can get a pretty excellent image from that TV. 4 or 5 years ago this was one of the best plasmas you could buy (if not the best) and 1080p sets were rare or nonexistant. Like many older plasmas it has a native resolution of 1024x768. Because the pixels are rectangular rather than square, you get a widescreen picture from a 4:3 resolution (1024x768).
I have 2 such sets (Sammy and LG) connected to HTPCs and the IQ is outstanding. Try this, set the desktop to 1024x768, adjust the overscan slider to 0, disable over scan on the TV (there should be a setting for this somewhere in the TV setup menus). This will give you a crystal clear 1:1 pixel mapped desktop, but the desktop will be stretched horizontally and so will be a bit distorted. Depending on how much non-HTPC stuff you do, this might bother you. Video will not be stretched and will be excellent.
If you don't like the distortion above you can try 1360x768 and let the panel scale it to 1024x768. Since it is only scaling on the horizontal axis there is very little blurring of the desktop fonts and it is very readable and exhibits no horizontal no distortion like with 1024x768. Video will be excellent.
Let us know how you make out.
New wealth is created in 2 ways:
You dig it from the ground (mining and oil)
Or you grow it (fishing, farming and forestry).
Everything else is just processing what you dug up or grew.
