Yesterday, Scott was at the Custom Electronics Design and Installation Association Show (CEDIA) and what was really telling was how few TV and home theater manufacturers were there. Leo says that's due to the bad economy and Scott agrees. While there weren't many TVs there, there were several 4K manufacturers showing their version of what is likely an LD designed LED TV (resolution of 3840x2160). Sony was there, LG, and even JVC. It surprised Scott that all the TVs were edge lit, and for a price of around $20,000, that's really disappointing.
First the size of the TV depends on how far away he's going to be watching from. He'll be 10-12' away from the screen, so a 60-65" TV would be best. Next he needs to consider how much ambient light there is, and if he can darken the room. He has a lot of sun coming in, so Leo recommends an LCD TV. The Plasma TVs aren't as bright and reflect light more.
