Just a quick note for those wondering;
YES YOU CAN! Use a 27″ iMac in Target Display Mode with a non-Apple device on the other end of the cable!
The 27″ iMac (last sold in 2010) can be used as DisplayPort monitor. This is important!; the 24″ iMacs that came after the 27″ also have a Target Display Mode, but they require a ThunderBolt connection, as opposed to a Mini-DisplayPort connection.
(Source: https://support.apple.com/en-us/HT204592)The 27″ is lenient in this matter and that is our loophole.
What you need:
- You need an iMac 27″ (Duh!) with Mini-DisplayPort (2009 or 2010 model)
- An ACTIVE HDMI to DisplayPort convertor. DO NOT confuse this with a DisplayPort to HDMI adaptor; you need SOURCE: HDMI, OUTPUT: DisplayPort. This device is one that is confirmed to function!; the DeLock 62667. Note the terminology; convertor as opposed to adaptor.
- The proper cable for your HDMI to DisplayPort convertor. For me a DisplayPort to Mini-DisplayPort cable was the proper one.
I tested this with my Asus ROG G752, and it works beautifully :)
Next step (and goal for this exercise) is to hook up a game console. This one springs to mind… The xbox one s with BattleField1.
