External monitor turns all green after MacBook wakes up
Sometimes after my MacBook wakes up from a sleep, the external monitor turns all green. I can still move the mouse cursor to that screen, but can't see anything else.
About this Mac: MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)
OS: macOS Mojave version 10.14.3
Graphics: Intel Iris Plus Graphics 640 1536 MB
Monitor: Acer CB281HK https://www.acer.com/ac/en/GB/content/professional-model/UM.PB1EE.001
Every time this occurs, it is fixed by restarting the computer. So I'm suspecting it might be a software issue.
Hope to hear if anyone knows the cause, and if there's a way to get around it without having to restart.
