I am facing the same problem. The Aspire R 11 Hangs when its connected to a Projector.
It's very embarrasing while conducting an session, in between my laptop keeps hanging. This has to be an hardware issue which needs to have some solution.
It hang's only when its connected to Projector { HDMI or VGA }
I have filed for an online complain, and the support team has assured me a technical person would visit. WIll surely share solution on the forum.
