I use a Toshiba TV that I recently attached an Xbox 360 to play with. It works ok, but there is some annoying input lag. PLEASE READ DETAILS
I tried to use "game mode" (supposed to help with lag) on the video settings for the TV but it is greyed out and I cannot select it. How can I access it? I seem to notice the lag mostly on the game Crysis 3. I have been using my Xbox for five years on a separate television without issues, although this one is a different tv.
