Does this hdtv lag with xbox360/ps3

Hey a friend of mine said this TV lagged with the 360/ps3 even on hdtv when they played T5 : Dr and GH2…can anyone clarify what the problem is?

A 360/ps3 is only going to lag on an HDTV if the resolution is set incorrectly, as far as i know.

ya figured i just want to explain to him…i mean…he had a few pro players play it but it seemed to have issues…any reason that will help is good…also this specific one was recalled due to issues with the screen output ( it cut off the bottom i believe or something ) and a chip was installed…would that affect it?
