No, simply two monitors with different resolutions (and different scaling):
Just to make this more difficult, monitor 2 (1920x1200 scaled 100%) is the main monitor, so all positions on monitor 1 (3840x2160 scaled 125%) are negative x (-1 to -3839) and some are even negative y.
I always put the IDE on the right 2/3 of monitor 1, that's why saving and restoring desktops in Delphi IDE's is broken on my setup since Delphi 11.
Also this is the reason that scaling in the Delphi IDE is broken on my system (and my home grown scaling in GExperts is very difficult to do and still has some glitches).
