I'm sure this has been asked before, and there were a couple of clunky workarounds at the time, but ...
I have 3 monitors on my PC, setup as: 24inch + 30inch +24inch. I use the 30 inch for Lightroom main window, and want to right-hand 24inch as second display.
Every time I use second display, it opens on the left monitor. If I take it out of full screen I can drag it to the right screen, and make it a little larger to try to fit the screen, but if I make it full screen, it goes back to the left.
This has been complained about for year (probably doesn't impact the MacBook Pro users so much) so am a little suprised if it hasn't been addressed. Any ideas?
I have even tried to swap the cables between the two outside monitor, but it figures out when I re-order them in Windows and goes bak the same.
