I have a 2019 Macbook Pro. I also have 2 2014 iMacs. I have them both plugged into my Macbook Pro.
I am able to get both iMacs to work in "target display mode" on their own with my Macbook Pro.
But when I put both in "target display mode" one of them always shows a blank fully black screen.
When I go to my display settings all screen show up as registering. I am able to move them around and change resolution. However, the 3rd screen is just black and unusable.
Any advise?
