hey there, i have tried looking around the net and forums for an answer but have found mixed results so i thought i would ask you guys myself and hopefully get a genuin answer. is it possible to use my iMac screen (2011) to run my xbox 360 thro without any noticible lag, ive seen posts where people have said its possible but lags badly, however i have seen videos on youtube where people are playing their xbox via imac screen without issues. is this possible and what would i need to do it?
