This is a pretty common occurrence for me on macOS with external monitors. I have thunderbolt going to a dock, then displayport from the dock to the monitors.

This is a pretty common occurrence for me on macOS with external monitors. I have thunderbolt going to a dock, then displayport from the dock to the monitors.
Waking from sleep will periodically just not find a monitor at all, or they will come up with the wrong positioning (left and right swapped). If I turn a monitor off, the other one (and the laptop) do some sort of resync operation that interrupts the display. It's annoying, but not something I would expect the industry to consider a priority; I'm not really sure it's a monitor issue at all.
- dawnerd 7y agoSame issue here, been like this for > five years. Almost like no one at Apple uses multiple monitors.
- Corrado 7y agoI have the same problem! My 2018 MBP can't seem to communicate with my Dell U3415W monitor reliably at all. Sometimes the monitor comes on when I touch the keyboard and everything is fine. Sometimes I have to "fake" a sleep cycle by shoving the mouse into the corner of the screen. And sometimes I have to go through a whole process of turning the monitor off/on, opening the laptop lid, disconnecting the Thunderbolt cable, and anything else I can think of. sigh it seems like this shouldn't be a problem in 2019.
