I have a MacBook Air M1 connected to a USB-C powered hub. Have been using it with an external USB-C powered HDMI portable display for years. The display started flickering after the 14.4 update. After upgrade to 14.4.1 today (2024.03.25), the display goes into power saving mode all the time. MacOS "sees" the external display. But, the display itself shows nothing - It displays "No signal"

Same here on 2023 MBP 16". But it's not even detecting the usb-c external display in MacOS. Only HDMI is working after the 14.4.1 update.

M1 macbook pro update 14.4.1 typec connect monitor display isn't working...
Since 14.4.1, usb c monitor and the port has become very unreliable.
It works for a while and drops the connection. I've had to reboot the monitor and Mac a few times now.
Mac stops charging via the usb c monitor cable and it wasn't charging even after connecting a separate adapter. Eventually had to reboot the Mac. Usually I don't reboot Mac for a long time (weeks or sometimes months) and it's generally for an update. But I've already rebooted it a few times now since 14.4.1 update.

I became so frustrated I just gave up trying to use a external monitor. I don' get it, Mac's supposed to be standards compliant so why don't they work with standards complaint devices? Never had a single issue hooking third party devices up to Intel Mac's but apparently that was because they were Intel??
Same issue m1 pro upgrade to 14.4.1 made my usb hub with hdmi stop working. I thought this was fixed with the 14.4.1 update =(
Ok rebooting the hub fixed the issue.
My cable is USB-C to DP1.4.
Doesn't work.
Same here.
