I did this a while ago and all was working ok. A few weeks ago I decided I would watch something from youtube on my TV and selected HDMI2. All that appeared was a blue screen. Have gone into settings on my PC and the only option is connect to external display which seems to be VGA connector. Have tried detect, but nothing happens. Am both stumped and annoyed. Don't want to spend all day googling for a solution, only to find the problem is not addressed. Hopefully someone here will have the answer.
