[quote name='DP2']What's wrong with Samsung? I have a pair of them and they work great for my Wii and PS3. I don't think you can find the T200 anymore, not sure how much luck you'll have on the T2370 either (whether they moved to newer models or not). Great sets, I always choose Samsung. Both sets have tuners, component, and an HDMI. 20" and 23" because who needs anything bigger?[/QUOTE]
Typically the best TV's for low input lag are LG, Sharp, and Panasonic. Unfortunately there isn't much of a selection in the screen size OP is looking for. Samsung's with the exception of some older models are notorious for input lag. Also you CAN find monitors that have component/composite connections. Sorry if it seems like people keep bringing up monitors but it seems like you want a dedicated gaming display.
