Does the official Apple HDMI adpator also have this limitation?

I am impressed that the iPhone 4 can do 1080 video. Not actually tried it - yet.


I'm sure the Apple HDMI adaptor can play 720p protected movies with HDCP enabled on the HDMI end; they specifically refer to movies in the description of the adpator.

Possibly the 3rd party ones are just using a non-HDCP compatible chip?

iPhone4 can't do 1080p I'm afraid. The iPad2 says it'll do 1080p for mirroring mode (presumably to fit a portrait 1024 pixel screen), but also doesn't mention video. I can't say more than the page says.
