Vegas movie studio 15 on new Acer Aspire 7 laptop.
When I press the Video Preview on External Monitor button it creates a white/blank screen (either on the laptop monitor or on the external HDMI monitor) and nothing is displayed on it.
I can successfully drag the Video Preview window to the "external" display,. I leave the Preferences -> Preview Device in the default setting.
