I'm not sure why you're seeing that. Typically, I use only the second monitor for full screen previewing of critical sections, and only rarely because it's so taxing on the CPU.

However, the 2nd monitor is only for display, and all the editing takes place on the monitor with the main PD window.

That's what I'm trying to do. My normal setup is to leave the laptop screen off and use the larger external monitor. With PD17 I extend the display (Win10) to the laptop. When I put the video display on full screen I can't do any editing on the external monitor where everything is: like the timeline, cropping window etc. It doesn't seem to be too big a drain. It's a gaming laptop so pretty capable that way. It's a shame too because I'm just looking at a video I thought I'd finished but now see small detailed errors I couldn't see before so will have to redo some things. The one thing in the non-full screen video on the extra display that might be a problem is this (somewhat irritating) box where every time I make a change in a clip I have to go back and set it to movie (instead of clip) so the video will go to the next clip. Maybe there a keyboard short cut for that procedure? If there's a workaround to allow full screen video display on the laptop and still be able to edit on the monitor I'd appreciate knowing how to do it. Thanks

There are a couple of settings under Preferences > Editing that affect Clip/Movie modes.

For what you're trying to do, it sounds like you don't need PD's Dual Preview mode so much as to use PD's modules full screen on your big monitor. Most of the tools have a maximize button at the top right of the window, and you can also set PD's main preview screen to full screen (or much larger than the default) by using this undock button:

Thanks. next time I do a project I'll be checking this out.
