On my 55" 4K TV I use as a monitor, I defined 18 split monitors and filled them with different colors, then I spanned an image across all monitors. Now I can't see where my DFPro monitors are. I tried padding, but sometimes it shows a black line, other times it doesn't.
Is there a way to show the grid lines for each monitor, like Show Preview, but without dimming the image?

Thanks for your quick response.

Perhaps you could provide an overlay to the picture with white (or selectable color) borders with green screen effect to preserve the picture, or overlay Monitor Color/Colour(Brit) on the image with opacity adjustments.

I have a number of other questions, if you prefer I can open each in a different subject.

Q2. How do you show a persistent split screen monitor number in each split monitor without dragging a Window over it? I may have missed it, but I could not find an Info Tag that does that.

Q3. Is there a way to autofill multiple split windows with background colors, preferably with selectable pre-defined color schemes, or propagate rainbow colors, or in user pre-define orders etc. Also an option to adjust the color scheme brighness and Gradient.

Q4. Do you have a larger set of Preset Splits I can choose from and modify? How about Presets with different colors already applied? See Ultraview presets: https://www.digitaltigers.com/ultraview-mini-49c.asp#
BTW: Is UltraView just a licensed copy of DP?

Q5. Can I set a different Monitor Config Profile and Wallpaper for different monitor configurations in multiple Windows 10 Virtual Desktops. I realize I could probably load a different profile when I changed the Desktop and/or set up Hot Key Combinations, but I frequently flip back and forth to other desktops and I believe that it would be too slow and cumbersome to load each time. Could any Functions, Triggers or Advanced Settings accomplish this?

Q6. Enhancement/Feature Request:
Instead of adjusting a monitor size using the old fashioned non-gui DOS type text sizes, make it a gui where you can:
Select a DP monitor window edge or corner and resize it and/or move it around like a Windows window, with the option of wrap, where other windows around it automatically resize, and/or make room for the selected monitor window. Much like you can move an image around in a MS Word doc and the text will automatically wrap around it.

Q7. How can I take a Monitor Config, populated with Desktop Wallpaper and copy it to another computer?

Sorry about so many question, but I am a retired Software Consultant that is used to providing customer enhancement requests to Research & Development Teams.
P.S. The more I use DP, the more I like it

I would love to see this feature as well. It would be very helpful to have gridlines, maybe even ones we could adjust colors and brightness of!!

Sorry for commenting on an old post. Curious if a gridline feature has been added to show the virtual line splits or if it's still on the list? Thanks.
