How to replace mini Displayport of an iMac 21.5" with a 27"?
I know that you cannot connect any external source to the iMac 21.5" to use its display. But the 27" mini displayport offers input so that you can connect, for example, your PS3 to it and use it as a display. My question is this:
How do you replace your mini displayport on an iMac 21.5" with the mini displayport of an iMac 27" and would it accept input?
