Q. I'm looking to purchase an HDTV and was wondering the difference between the two types. Is it worth is to spend the extra money for LED? How much better is the performance of an LED?
A. LED and LCD HDTVs are actually both LCD. The only difference is when the HDTV says it's LED, it's actually referring to the type of backlighting. LEDs use light emitting diodes which turn on and off extremely fast. This helps to make dynamic contrast possible (black scenes are darker, white scenes are brighter). LCDs use fluorescent tubes that are not so fast. Performance wise, picture quality varies greatly between manufacturers in regards to both technology. Before making a purchase, do your homework and read up on specs and reviews on websites like http://www.cnet.com and http://www.specsandreviews.com
How do I choose the right LCD TV?
Q. I am planning to buy a 32" or 37" LCD TV (HDTV), but I am not sure about the best specs. Do you have any brand preferences?
I would like to use the TV occasionally to play games, like with pS2 and XBOX 360/

A. If you're going to be playing video games on it, I don't recommend getting a LCD TV. LCD TV's still aren't quite as good as .. well, anything else in terms of refresh rates. Refresh rates matter anytime fast movements take place (such as video games). The higher the refresh rate, the higher the chance of blurring. Many people don't notice it, but unfortunately I'm not one of those people and it bugs the heck out of me. I was in China/Japan/Taiwan last month and I've seen the latest models of televisions. LCD has certainly come a long way, but it's still not as good as plasma tv's were two years ago. The higher end LCD TVs that don't have as much of a blurring issue but is also as expensive as a car. LCD has it's pluses, higher resolution for example ... but I personally think it stinks for gaming. That's my opinion of course, so I urge you to check out sports on a LCD TV and see if the blurring bothers you.

"Plasma pundits will also tell you that some LCD screens have a tendency to blur images, particularly during fast moving scenes in movies or in sports. While that was true for older generation LCD screens, newer models have improved significantly - so much so that the differences in performance between LCDs and plasmas in this regard is almost negligible (here's a tip -- if you're shopping for LCDs, check the refresh rate. The lower it is, the better the image quality in fast moving scenes)."

"While the "response time" of LCD TVs has markedly improved in the last couple of years, they still suffer from a slight "trailer" effect, where the individual pixels are just slightly out of step with the image on the screen. During fast moving sports scenes, the most discerning eyes can detect this slight motion response lag."

The other answerer was commenting on how the life of a plasma TV is poor. That's simply not true anymore. Do your own research on that matter, this hasn't been an issue for quite some time now. Don't believe what he says about being an idiot for buying a plasma. People who say that can't see the difference in image quality, perhaps their attention to detail is lacking .. who knows. He has very strong opinions towards plasma tvs and hybrid cars, those are exactly the wrong people to listen to. Keep an open mind. For the record, I have a HDTV CRT, Plasma TV, and three LCD TVs (all larger than 32'') .. they all have their purpose. The LCD TVs are great for connecting to computers, they have high resolutions. For watching TV, nothing beats CRT and Plasma... yet.
