Also. What's the difference between Plasma, LCD and LED TVs?
Different technologies, each with their own positives and negatives, but nowadays the difference is almost an irrelevance.
In simple terms, plasma used to be used more for larger displays and LCD for smaller displays.
I personally can't see the benefit of LED tv's. Yes they are only roughly 10 cms thick, but when wall mounted its irrelevant and really isn't worth the extra cost. I think im also right in saying the picture quality isn't as good either. Its a relatively new technology, and if i was you i would ignore them.
