MacBook Pro (16" 2019) Does Not Recognize Correct Resolution I'm having a rather annoying issue with my MacBook Pro 16&quot; 2019 device since upgrading to macOS Big Sur. Every time I plug my device to my 4K monitor into the device (via USB-C to USB-C, or USB-C to DisplayPort), macOS will show a maximum resolution of 1600x900 but my monitor's recommended resolution is 3840 x 2160.

I currently have a workaround to resolve the issue which is the following:

I switch from 1080p resolution to 1600x900
Un-plug the cable, and plug it back in again
Then switch to 3840x2160

This process can be tedious and take a while to complete (between switching resolutions). Is there any solutions which people are aware of?
These are the details of the device and monitor

macOS Version: 11.2.3
Model: MacBook Pro (16-inch, 2019)
Processor: 2.3 GHz 8-Core Intel Core i9
Graphics: AMD Radeon Pro 5500M 4GB
Monitor: BenQ EW327OU

These are the things which I've done to date

I can't pin the issue on the monitor, as I've been using a MacBook Pro (2017) with the monitor for a week or so without a single problem.
Used ColorSync to repair any issues with the monitor profiles
Used various other cables such as HDMI, USB-C to USB-C and USB-C to DisplayPort.
Reset NVRAM and SMC
Re-installed macOS
I can't reproduce the error in Windows via Bootcamp, so I'm confident it's OS related.
Confusingly, it does appear to be wire related. I found my original USB-C to USB-C cable which came with the monitor and it resolved the issue.
EDIT (26/03/2021): I spoke too soon. The issue has occured with this cable as well. However, as noted by Luciano, it appears to be a known bug by Apple and will therefore be resolved in a future release.
