Best set up for a music and video live performance

Dear all
I’ve tried searching, sorry if the answer already is on here.
I need to do a gig in a couple of months and it is to have my music videos playing ona projector. Cubase seemed to be the best way to do this.
Has anyone any experience on this or seen a good thread here on it?
Should I just ‘extend the desktop’ over to the projector by using my hdmi out, on my laptop, and drag the video ‘F8’ window over there?
Or is there a more elegant and stable way? I can’t see how to maximize the video window to full screen in the method I mention above.
Am I missing something obvious?
Thanks very much
