I currently have a Dell WD22TB4 dock, updated to the latest software version, connected to a MacBook Pro M1, with two Dell S2722QC monitors connected via USB-C cables. Unfortunately, only one external monitor works. The MacBook Pro is running the latest version of macOS, and the DisplayPort drivers are up to date. Additionally, I’d like to mention that I previously used a Dell D6000 dock, and everything worked flawlessly.
I’d also like to add that I tried various connection setups following the instructions on this
https://www.dell.com/support/kbdoc/e...s#Dual_Monitor, but it made no difference. Depending on how I connect them, one monitor works, and the other doesn’t, alternating between the two.
