What size display?
Two x 27", don’t want to go to huge monitors, takes away my view to other things. 
Have you tried 2560 x 1440 resolution with 100% (no) scaling?
Now you’ve opened the door, what are the “other things”? 
Yes, 2560 x 1440 @ 100% is one of the 43 we tested. 3840 x 2160 @ 100% came out as most sharp, easy for the eyes and give acceptable workspace. At least, this was for SolidWorks 2019. Now pre-testing SolidWorks 2022, there are a lot of differences. <()>
I struggle to see 3840 x 2160 at 100% on a 27" monitor. That’s a little over 160 pixels per inch. I would not be at a safe distance from the screen. 
Sorry, slip of the pen , 3840 x 2160 @ 200%
Thanks for the update. I was seriously wondering how by my eyesight was getting if others are using full 4k on a 27".
Wow, I think this meets the definition of a hijacked thread.
I’ve been raging about SW restoring on the wrong screen for years but have not found any solution.
Remember when there was a post from SW (years ago, possibly from Matt Lorono) asking what multi-monitor support means to you? Still not addressed. Waiting, waiting,…
My apologies. The hijacking was my fault. 
Back to the dual screen and SW showing up on the wrong one. I hooked up a second 43" 4k display Monday to test this out. After a little bit of acclimation (and a bit of vertigo), I’ve decided you guys are right, dual monitors do have merit.
I’ve realized that I never use the “Show Desktop” button in task bar. I don’t use desktop for much of anything. Might be why I don’t notice problems with windows restoring to the wrong location.
