    I am a current PC user and I am planing my purchase for my i-7 27" iMac but I have a question regarding the Mini Displayport. I frequently repair PC's and use my display as a second input to connect to the PC that I need to repair. I have been reading the spec on the iMac and noticed that the Mini Displayport can be used as an input. Can someone tell me which adapter that I need to purchase to make this happen? Thanks

    I guess that would depend on what kind of connector the PC has.

    Oh yeah, I forgot to mention that. I was thinking VGA would be the most common. But if I go with DVI then I can use an adapter to convert it. So DVI would be the way to go.

    Right now there does not seem to be a confirmed method of converting and scaling DVI/HDMI signals to work correctly on the new iMacs. The Atlona DVI/HDMI to Displayport active adapter has been confirmed to NOT work since it does not support the iMac native display resolution.

    The only successes that I've seen reported are from people using display adapters that have a Displayport built-in, and then only the 4xxx series ATI cards (like The 5xxx series cards seem to have a problem and I've seen many reports that they are not working.

    Was just reading that Atlona is officially supporting the DP200 active DVI/HDMI to Displayport converter for use with the 27" iMac ( I'm not sure what has changed since the DP200 still supports a maximum resolution of only 1920x1200. Even if you could get a video signal to show up at that resolution - and there are reports that this does not work - then you'd be looking at a sub-optimal image since the native resolution of the 27" display is 2560x1440.
