Good information. I'm using a 40 inch LED Samsung TV as a monitor and have it set for 1920x1080 (1080P) at 120 hz for gaming. It works very well and looks very realistic. I still have my older 20 HP monitor that is actually capable of higher resolution than the TV, but I made the decision that size matters. I'll wait and see what happens with the 4 K LED TVs as the prices start to drop.
