The story is as follows. I have never had any problems with connecting my Mac to the external projector through the Minidisplayport-to-VGA adaptor (genuine Apple). However, now it doesn't detect any external projectors/monitors. Juggling with the adaptor sometimes help but the connection is still very unstable. I assume there are some problems with the port itself, but probably someone had the same issue.
P.s. Detect Displays, rebooting and other obvious solutions didn't work.
