-A lot of computer monitors are very good for gaming and come in at 32". Many have several HDMI inputs, Display Ports, etc. and have 1-5ms lag.
-Look for a good processor. Some cheaper models of good manufacturers can be sluggish. Try the TV from startup as well since some take quite a long time for users to have access to inputs, etc. even if the TV powers up quickly.
-Obviously look at input lag in game mode.
