The application is on a free 10-ten-day trial with a EUR 14 price to register. This was originally free for download but has now been made available for USD 4.99 which is still a reasonable and affordable buy as it is a very useful software anyway.Ī more sophisticated hack is SwitchResX, a shareware application that allows extensive control on (1) Monitor Resolution, (2) Color Depth, (3) Video Mirroring, (4) Display Rotation, and (5) Display Overscan among others. This is supported in OS X Lion (10.7) and later versions of OS X.

The 14-inch MacBook Pro with M2 Pro and M2 Max takes power and speed to the next level, whether it’s on battery or plugged in. I come back, and no matter what I try, the only way for the MacBook to detect the external display again is to restart the computer! Here's my situation: I have an external monitor hooked up to to the MacBook's display port, I walk away from my computer for a few minutes and it goes to sleep. ( Update: Now running macOS Mojave 10.14.5 on a 13-inch 2018 model, and this is still a very annoying issue).
