It's your video driver, not vnc. I had the same problem with some new fangled 'super smart' intel drivers that we're going to save the planet by turning off the video if there was no screen detected. A bit of a problem is a server rack with 8 or more machines.
Solution: Remove the 'super-smart' video driver and use the default mickeysoft driver.
