If we working on the vector nodes cannot see the raster changes on the display in color.
I think since we can use multi monitor we can display both on different screen.
Left monitor would be vector
Right monitor display raster.
Yes, it's possible. With your work file open, go to Window>New window. it will open new window of project you work on. Now you can undock it and drag it to your right monitor. In this instance, switch your view mode to pixels. I teseted this on win 2022 but ibelieve it should work on mac, 2019 edition
What type of display are you using?
