SMPlayer Support Forum

Hello,
I could really use some help with Smplayer.
I have one monitor and a projector attached to my pc. I start up a video and it plays just fine but when I slide it from the monitor to the projector, I can see the smplayer window just fine but not the video. It was working when I first loaded it but now it is not. Could I have somehow selected to play in the toolbar?
Please help as I am using this for a Christmas display.
Thank you very much!

You provide very little info. What OS are you using, windows or linux? What video output are you using? (try to change it)
