HDMI Monitor Not Working After macOS 15.4 Update with Dell UD22 Dock

[jonkad]

I look forward to the updates on this problem.
I run two UD22 on my Macbook Pro M4 with macOS 15.4 one in the office and one at home.
The HDMI port on both has not worked since the macOS update.

As an additional data point -

I have a very similar setup to the OP - MBP M3 Max, Dell UD22, 3 x Dell U2723QE

Two monitors connected via DP, one via HDMI

all ran fine upto and including macOS 15.3 but the HDMI stopped working since upgrading to macOS 15.4 and then 15.4.1 (when connecting third monitor to USB-C instead of HDMI, the monitor blinks on and off with a time period of about 20 seconds)

running DisplayLink driver 1.12.1 and UD22 has latest firmware from dell.com

it sounds like a fix is on its way so that's great news - in the meantime I'm connecting the third monitor directly to the MBP with USB-C

I am facing the same issue. My setup is MBP M3 Max with D6000 + 3 monitors. Only 2 of them work at a time.

I'm using DisplayLink Manager 1.12.1 and Sequoia 15.4.1.

Do we have a ETA for the fix to be released?


Thank you.

No HDMI on second display after 15.4.1.

Just upgraded to new Display Link 1.12.2 the other day.
HDMI with Dell UD22 still doesn't work.
Any ETA for a fix?

I am using a UD22, and after upgrading from macOS 15.1 to 15.5, HDMI no longer works through the dock—however, connecting HDMI directly to the MacBook still works. Could someone please provide an ETA for a fix as soon as possible?
