    Hi guys,

    I want my LED Cinema 27" connect to my computer. The Screen has a Mini Display output, and I need to connect the Mini Display it to a converter, and out HDMI to my computer.

    What I found a solution was a Belkin AV360. According from the internet and reviews I read, the converter doesn't support full 1080p HD quality and high resolution.

    Is there any better product out there where I can get? I tried and tried to googling around, but for no info didn't come crossing my eyes at all.

    I might be blind, or suck!

    I hope someone could please help me out!

    Thanks a lot!

    There is a reason why when you convert from HDMI to Mini Display Port, you may not get the full 1080p resolution, because of the EDID settings restrictions. Read the FAQ of that product, also you may want to contact the manufacturer to make sure before you purchase.

    This is what it says in the specs:

    *The 27-inch Apple iMac and Cinema Display EDID will not accept HDMI resolution of 1920x1080 (1080p) therefore sources must be set at a matching resolution of 1280x720 (720p) for full screen HD playback.

    It is a restriction of those displays. no way around it i guess.

    Thanks a lot for the reply!

    I read the FAQ section, and I came across to this

    Why do I have to set my sources to 720p? - 5/18/2010
    The need to set your source to 720p is a limitation due to the iMac not the XD. Here is why: the EDID (extended display identification data) embedded in the display only accepts two input resolutions: 2560x1440 and 1280x720. The first resolution is not supported by PS3 and Xbox because the highest resolution output they support is 1920x1080, or 1080p. But since the iMac doesn't recognize 1080p input resolution, the sources must be set to 720p for proper video pass through. The XD features up to

    So if I understood correctly, it all depends on my graphic card PC how much it can take the resolution?

    It is a restriction on the LED Cinema Display. It only accepts 2560x1440 and 1280x720. It does not support full 1920X1080 (1080p) resolution from an HDMI source, but it does if it is coming from a pure miniDisplay port source.

    So, if you connect your laptop/desktop to the LED Cinema Display via HDMI to Mini Displayport adapter, the LED Cinema Display will convert that resolution to 1280X720 (720p).

    Your computer is a desktop PC? It might be easier and cheaper to just get a basic gfx card with a MDP output.

    Hey guys,

    Sorry for long reply. Been busy for some days now. I bought the Kanex XD converter, and tried to plug it on my computer. Nothing shows up on my Cinema LED Screen at all. Whats up with that? Just curious if the Kanex needs to have an input for MagSafe to work too?

    SidBala: I'm using a laptop so it's not possible to switch Graphic card at all. Sucks big time!

    EDIT: just as you know, I have Apple LED Cinema Display 27" which is the cable is stuck on the back of the monitor. I can't take the cable out back of the screen.
