Panasonic TH-37PWD7UY Professional Series 37-Inch HD-Ready Flat-Panel Plasma Display
Don't Know What your Problem Is !!
The 37 PWD as well as the 42 PWD Panasonic are wonderful panels. If your resolution is horrible, your source must be horrible. It is universially agreed in videophile circles and forums that these panels are the best buys available and are capable of remarkable picture quality. I have 2 of them and could not be happier.  If you want confirmation take a look at the AVS forum and do some reading.
