I read this post http://blog.fosketts.net/2010/01/05/27-imac-monitor-tips/

However if I read the specs from the iMacs it says only Mini DisplayPort output, which btw I cant see on the image.

Is it still possible to use the iMac also as an external display for a PC with Display Port or a Macbook?

Essentially, mDP on 2011 iMac has been modified to be a Thunderbolt port. Too bad they have identical port, but works very differently.

Thunderbolt port works as universal I/O port, and this include display mode. So in case you want to use iMac 2011 as display, you need some sort of adaptor.

Whether it is adaptor for mDP-Thunderbolt, or HDMI-Thunderbolt, or even DVI-Thunderbolt.

It's not just mDP port as we know it all along. So you can't use it with another PC with mDP but without Thunderbolt.

That's why currently there only 2 devices on earth which can use iMac 2011 as display directly. Macbook Pro early 2011, and another iMac of the same gen :D
 
Thx a lot for ur answers! I guess I need to get an older iMac if I want this.

Or just live in the knowledge that a third party will make an adapter. i'm sure this will be called a gamble by some, but in all seriousness, TB is soon going to be standard on all apple machines, and the need for a universal display mode will be overwhelming. Theres an adapter for absolutely everything, but sometimes with new tech it takes a while.

I was in the same position as you as i need my imac act as my monitor for everything, including blu-ray and xbox, but the adapter will come!
 
Well, I have been searching and searching for a solution to connect my Xbox 360 to my 2011 iMac since the HDMI to mini-Displayport converters are useless since Thunderbolt.

This is the best option I have found: the Blackmagic Intensity Extreme.
It's an HDMI capture card which uses Thunderbolt. It relies on a video editing program like Final Cut or Adobe Premiere but if you're not recording put the playback on fullscreen you get the same result :)

As long as you're not recording the signal there will hardly be any lag.
It's not a perfect solution (limited to HDMI and it's resolutions) but you won't have any EDID- or brightness problems :) I really hope this works lag-free since this could be THE solution I have been waiting for (and so many others).
