Up until tonight I was able to use my MBP in clamshell mode with no problems. I plug in my Moshi MDP to HDMI adapter, put my MBP to sleep and wake it up with my magic mouse. This still works... For one second max, until suddenly I get a no input error. I am ale to replicate this on multiple TVs/monitors.

I can only think that it is the Moshi at fault... Except that it still works when using the external monitor as an extension to the desktop.
