Here put simply is the differences between Plasma and LCD
LCD's: Higher resolution (Sharper),brighter, non-reflective.
PLASMA: Faster processor for movement, (Smoother images) more natural colours (because of higher contrasts),and 3 dimensional look.
Most people are buying LCDs, as with HD TV they look that much sharper, etc. If you are a sports fanatic, recommend Plasma still, because of lots of movement, but for general TV / Dvds and gaming, LCD. Follow the trend!
Both are great technologies, just different! Similar prices across the board too.
It seems that no matter who you talk too, or read reviews about, Plasma still comes up with the overall best picture, but most people would rather have Sharper Image, and Non-Reflective screen, than a more Realistic Image with Smoother Movement?!?!
Recommend: Sony/Samsung/Sharp LCDs. Panasonic/Pioneer/Samsung plasmas.
Hope this helps.
