Im in the market for a big screen. There are three models I am looking at: the Toshiba 46HM95; the 52HM95, and the Samsung HLR5067WX. Thought about the Sony KDS-R50XBR1, but not sure of that either. So my question is: what is better? My room size is 11x22, but ill only be using a portion of the room for the HT setup (11x15). Some of these TVs mention computer compatible. What exactly is that? One more thing, i tend to notice the rainbow effect. is there a distance this begins to be less noticeable? Thanks for the help.
