I’m using a Luna Display with a 2017 MBP as my primary display and a 2015 5k iMac as my secondary. I’m reasonably happy with how it has performed since I got it this week, but it’s sometimes noticably sluggish.
Is it possible to improve performance by directly networking the machines together? Maybe with a thunderbolt 2 cable or ethernet cable? (Either of those would require an adapter for my MBP, so I want to know if it will work before purchasing those parts.)
