At this point with the technology I don't expect any panel in the price range like the two below to do exceptionally well with SD, especially w/ cable or satellite. I tend to discount any reviews dealing with panels and their SD performance. Personally, if SD performance matters that much you would be best served IMO by buying both and doing a side by side test at home under the lighting conditions where the new HDTV will be used. This would also let you determine which one had adequate blacks/ colors, etc. The showroom floor is totally different, uncalibrated, and generally puts all the sets in torch mode that is not like at home usually. Since everyone's SD signal/feed/home wiring and hardware is different enough to begin with, each location has the potential to behave differently in concert with different HDTVs. You won't know which of the two sets is better until you test in in your own home in your situation. While you probably can't switch cable providers, you can start by making sure your wiring is up to snuff before any new TV is delivered. PQ starts there IMO, something which is even ignored by a lot of folks still w/ SDTVs.
I am looking for a new HD TV and have basically narrowed it down to the Samsung A650 (46" or 52")series LCD and the Panasonic 50PZ800U plasma.
I currently own a 42" Samsung plasma and over all like the picture. But LCD seems to my eye to have a "depth" (perceived or real)when viewing HD content and Blu-Ray/HD-DVD movies that the plasmas don't.
However, in the reviews here on c/net and elsewhere, they always test with HD DVD or Standard DVD sources, unless I missed something.
Which of the 2 tv's that I am considering perform best in the SD and or Digital content world of cable (RCN) viewing??
Any thoughts from the minds at c/net?? LOL..
