Hi everyone, I am trying to connect my Xbox360 to my Imac 27 (late 2009) via the Dr. Bott Digital Video Link. First I switched the Xbox360 to 720p using a TV and then I connected all the cables accordingly (Xbox -> Hdmi -> Converter -> MiniDisplay). When I then press cmd+F2 on the Mac, I can see the Xbox Home Menu and I can navigate through the menu, but the screen flickers constantly and the sound breaks from time to time. If I switch to 480p (I can only choose between 480p and 720p) the screen only flickers, if I switch to 720p (which would be the only resolution that is suitable for playing), the screen does not only flicker, but goes black every 3-5 seconds for 1-2 seconds. ( I dont know if it is important, but the Xbox tells me that both resolutions would not work with 50Hz when I switch between them). What is the problem? I tried all the other resolution options in the Xbox menu without success and I tried the same thing with a different Hdmi and a different Display/MiniDisplay cable but the problem persists still. Does anybody have an idea what to do? OS X is 10.8.5 Thank you so much in advance! Best regards!
