Should be ok, you will have to be at least a meter from the tv and will notice the pixels more than on a monitor but likely you will also have a wider viewing angle.
Minimum 1080p though, hd ready would not be nice.
Try getting higher frequency/highest you can.
Also, take a laptop and cable with to the shop, insist you want to try before you buy and have a couple of games pre loaded on it to test with.
