HD TV

My brother bought a 32 vizio flat screen a few weeks ago. But only recently did he get High Def channels on to the set. the picture from regular cable to HD is night and day with clearity. It is amazing how big of a difference it made once he got those channels. I read somewhere that they are working on "laser" sets. The use lasers to project the screen and is said to be so clear that your there in detail. I dont remember much about it but that it was being tested and not out yet.
