Hello,
after upgrading my MacBook to macOS Catalina I can't connect external displays. Minutes before installation it was all properly working. It seems like MacBook doesn't detect them at all.
Anyone has similar issue? Any hints?
The displays are not Apple (HP, Asus).
I have a MBP late 2015, I had 3 monitors and since OS update. Just 2 monitors are working. I try active adapter, no succes, I also have a dock station, no success.
Did you manage to solve this? I have the exact same problem. I tried another display and it works fine though. Its just my old display, as though Catalina can't work with it?
Update: STILL WORKING!
I've had NO issues with my external Apple Cinema display and Catalina, since I used the above "New and working setup". It's been about three weeks now of daily use! :D
I solved this problem. If you are using DisplayLink devices/connectors you need to update the software every time you update the OS.
YES!
My monitor has been rendered useless all of a sudden! How can they take this long to fix this huge problem?
Firewire to HDMI
my external tv displays connected to my MacBook 2016 via hub/dock stopped receiving a signal from the computer after the update. The display are shown to be connected but nothing else.
I am also having this issue, and I am experiencing crashes quite frequently. Cmon, Apple, get it together! I work in the clam shell and use my external monitor as my primary. This is ridicules.
do you still have a Driver for the:
