I bought Samsung 6 Series 46" FullHD. 
It is very nice TV. 4 HDMI ports, 2 USB, Ethernet. It has built-in media player for viewing Videos and pictures from USB or network. 
Games look great. But not always play that way. 
First thing I did when I hooked it to my console? I did latency test using Beatles Rockband Rickenbacker Guitar. 
 120ms for video and audio dissaponted me. 
It is great for most single player games. 
But I miss in quick times events here and there. 
Playing online is no better, because it has its own latency as well.  
I have sound coming out of y PC speakers when I play rockband.
So I play several games using FullHD monitor instead. 
 
I would like to find out the panels above 46" and receivers with 0 latency.
