Great. Besides looking fantastic, does it work well? ;-)

That is very strange. Can you elaborate on the "a different usb
device"? Can you give us exact steps to repro?

Correct. We cannot reconfigure while running. You can in some cases
where the 2 video ports are on the same card and you have recent
drivers. But not inserting a new video device as we do in this case.

Please try this again -- the external monitor will take a few seconds
but in my testing it does come back.

Minor oddity I guess.

thanks for the testing!
