Any one else having problems with the MS VGA adapter with projectors on the Surface Pro? I've successfully used it with a monitor but I've tried it with two different projectors and no luck. I was out at a customer site yesterday, tried to use there Acer projector, no luck. I managed to get a picture for a few second and then it went away. It was embarrassing, the customer had to let me use his Mac book to do my presentation.
