Apple macOS Big Sur 11.1/11.2 has external display connection problems –

Since December last year, there have been multiple reports regarding Apple macOS Big Sur connectivity issues. According to the latest report, the Apple macOS Big Sur versions 11.1 and 11.2 has been experiencing external monitor connection problems.

The first problem is that the USB-C port does not recognize the external display, making the external display unusable and unable to connect. This issue affects DisplayPort and HDMI displays connected directly and through hubs and adapters. Some users said they encountered this problem after upgrading from 11.1 to 11.2.

The second problem is the display problem. Some external monitors cannot work at 4K 60Hz but are locked at 30Hz. In some cases, 4K displays are only recognized as 1080p displays. One of the earliest reports of this issue appeared on Apple community on December 14th.
