    I bought the Belkin AV360 HDMI to Mini Displayport adapter last autumn to connect my xbox to 27" iMac. After few weeks of happy gaming iMac just stopped recognizing xbox. As far as I remember, I didn't change anything (though osx updates may have been installed silently).

    What I've done so far:
    * Checked all cables (HDMI, MDP, USB power)
    * Tried other cables (HDMI, MDP, USB power)
    * Did SCM and PRAM reset to iMac
    * Tried another Belkin AV360 adapter
    * Downgraded OSX from Lion to Snow Leopard (some people have had target display mode issues with Lion)

    No success. :-/

    Please help!

    In the core of a black hole.
    You could see what was installed on the Mac and when, click on the Apple Menu>About This Mac, a window pops up, then choose More Info..., another window pops up, choose System Report and in System Report choose installation.
    There might have been an Firmware Update in the meantime, if this is the case then I think you can't do anything about it.
