i realise this is a late post, but i bought the T220HD and used the hdmi cables and for sum reason i could not aim on the tv, i assumed there must be a small input lag so i ended up buying the vga cables which supposedly minimise or eliminate inputlag, but i still cannot use this tv, my aim is horrible, and when using a cheaper 19" hd tv it feels far more responsive and my aim is by far better.
overall the appearance of games is amazing and its a great looking tv, but if your a serious competitive gamer like i am i wouldnt recommend it.
