Ahhhh.... the eternal debate it seems - plasma vs. lcd. So I recently finished my basement Home Theatre and purchased my first HDTV flat screen - a Samsung LN46B640. Here's why: Not too expensive - I got it for $1299 at BB Liked the square look Do not need lots of bells and whistles including the online features and widgets The picture looks great I chose this LCD as opposed to a Plasma for the simple reasons that I have been affected by the negative hype that plasma's have gotten over the years. After reading and researching, I know that these are silly fears with the new plasmas being produced the past few years but for some reason couldn't put it past me when I made the decision. HOWEVER.... I have a lighting controlled environment (basement), DO NOT game or use it for online things.... and really designed just like watching sports (football in particular), movies (action) and some regular tv shows. I'm a perfect Plasma candidate i know... After taking back the first defective-out-of-the-box 640 lcd, i picked up a brand new one. The picture is great! But I do notice that during football games and fast action sequences, there is a blur at times like a "comet tail" off fast moving hands or objects and sometimes it looks like "heat waves" are coming off the football players.. . Also, when you get the close ups of the football players and they are walking to the huddle, you can see some "odd" things happening around the lines of their face gaurds with the background images... Is this a response time or refresh rate issue? Is it a calibration issue? My questions to the home theatre gods are these: 1. Would a Plasma have these same issues with fast moving scenes? 2. If I was to return my LCD for a Plasma which of the following would you choose? Panasonic TC-P50G10, Samsung PN50B860, Samsung PN50B850 or the Samsung PN50B650S1F The Panny and Samsung 650 plasma's are less expensive right now and the 850/860 are only about $50 more I thank you all so much for any advice!
