"Apple's iMac 2011 showed that this compatibility is limited to the video output, as video input is incompatible with DisplayPort and mini-DisplayPort devices, and only allow Thunderbolt-equipped computers to send a video signal to 2011 iMac's through Thunderbolt cables, exclusively, breaking compatibility with existing DisplayPort and mini-DisplayPort equipped computers."

This is unclear to me and badly formed. Is it even relevant on this page?

Thunderbolt equipped iMac (early 2011) can transmit video out through the Thunderbolt output to Mini display port equipped displays or to other thunderbolt devices that accept video over thunderbolt. They can also accept video from other thunderbolt equipped systems, such as the MacBook Pro (Early 2011). This information is posted on the Apple website.

Agreed. I second Victor's concern, and I am going to remove the text from the Thunderbolt (interface) page. I have no direct interaction with ThunderBolt hardware (other than what I read online - I am in the market for a new computer), but the syntax of the paragraph is confusing and the content is (probably) wrong. If it is not wrong, you are welcome to replace it with a clearer (and documented) version. Asmendel (talk) 15:10, 27 May 2011 (UTC)

The point is that Thunderbolt could not accept mini DisplayPort video stream, and could only output mini DisplayPort video streams (DisplayPort Protocol on mini DisplayPort physical port).

mini DisplayPort equipped 2010 27inch iMac input mini DisplayPort video stream by their mini DisplayPort port. Thunderbolt is not fully compatible with mini DisplayPort interface in the sense that it could not input mini DisplayPort video stream, just output mini DisplayPort compatible video stream.

You could not write that Thunderbolt is fully-compatible with mini DisplayPort specifications, when it only implements parts of this protocol.
