Hello there.
I'm using a MacBook Pro (Retina, 15-inch, Mid 2015).
Today I updated to macosx big sur 11.3 version.
After updating, the 165hz monitor I used with Thunderbolt 2 is not working.
Can we please help me? :(
The cable I use is:
MacBook Pro 15″, macOS 11.3
I have a similar issue and it seems been solved after I updated it to 11.3.1.
My problem was solved after I restarted the OS.
I would contact the vendor of the cable and ask them if they need a specific firmware to work.
Also, SIIG makes some good USB-C to Displayport adapters that do work under Big Sur. I would check at their cables to see if they have any that work for your older DisplayPort connector. I have used Moshi adapters for HDMI that work fine on the same MacBook Pro on Big Sur. I don't have any Displayport monitors unfortunately to test.
I had to start my laptop 6 times before it recognized my 2 external 4K monitors - very frustrating ..... took 90 minutes including the original update first thing this morning
I'm using the same MacBook Pro (Retina, 15-inch, mid-2015) and a Mini Displayport->Displayport 1.4 cable.
The Mac no longer recognizes the Monitor for audio output. The monitor no longer appears as an option to choose as an audio output. The image works good, but the audio stopped working on the monitor.
Yes. I think there were a few problems after the update.
Thanks for your mention. I use M1 MacBook Air. After I update the system to 11.3.1, it still does not work
Macosx Big Sur 11.3 External monitor does not work.
