Two things to look for. . .
in any large screen HD TV while viewing SD programming. They are called mosquito noise and screen door effect. Mosquito noise is the little artifacts or fuzziness around an image on the screen. It can be very apparent in a standard def picture. The other, screen door effect, is the little squares on the screen that make you think you're looking at the image through a screen door.
Some TVs handle this better than others, and since 95% of all programming is SD, it's something to think about.
Another consideration is the native resolution. Since HD is defined as 720 or 1080 lines of horizontal resolution, all but the newest flat panel screens are 720. I believe Panasonic now has a flat panel with 1080 lines of resolution, but it costs eight grand. Most of the larger rear projection TVs have a native of 1080.
When any HD TV receives SD broadcasting, 480 lines, it upconverts (adds lines of resolution) to either 720 or 1080, whichever is its native resolution. Again, all TVs do it differently, and some better than others.
Which is why, myself, after selling all these TVs for a while, and watching them for eight hours a day, and comparing HD and SD, and was able to put a digital HDMI signal into them, chose the Sony LCoS 55" for my TV. It will handle 1080P. And the above mentioned considerations are not there on my TV. Nada. Zip. SD programming is excellent and HD looks like film.
