Same Here, Sonoma 14.3.1. M3 Max, DisplayLink Manager v.1.10.0 (Build 117). Hope to see update sooner rather than later. Was working fine, now I have to plug it/restart the device (i-tec) several times in order to get it to work. Not sure what makes it "click", though.

Well, that did not last long. Took the night off and this morning does not function. Black screens again. DLManager is not recognizing external monitors and I cannot allow coz the system prompt does not appear. Rats!

Same problem
 

Have two external screens. At first only one was showing, today none. I also use a windows machine on same setup and that works fine, only the MacBook does not work at all. Was fine until yesterday. Any suggestions what to do?

As for OSX systems, this could be workaround, until we get new driver. It seems that turning on "prevent automatic sleeping on power adapter when the display off" prevents further waking issues, once connected with the station. Problem that remains is connecting to it, which is a hit & miss at this point.

Second Monitor Not Working
 

Similar experience with the following setup:

• iMac (M1)
• 2 LG UltraFine Monitors
• Belkin TB3 Dock Pro
• StarTech USBC to DP1.2 Cable & Adapter
• macOS Sonoma 14.2.1
• DisplayLink 1.11 (also tried 1.10 & 1.9)

Symptoms:

• First monitor through Thunderbolt works fine
• Second (DP1) monitor detected by system settings
• Second monitor shows only black screen
• Can move mouse to black screen - just can't see it

Nope, reverted to completely disconnecting all monitors, devices after a while.

This fixed it for me!

Relaunch DisplayLink from Applications folder

For me, problem solved.

Thank you! This got me back up and running.

One small tweak required for me. I have two external displays for an M1 iMac. I had to swap the connections between the two and then swap them back. I have no idea what this reset, but it worked. Otherwise, I still had a back screen on the DisplayLink adapter screen even though it was recognized.

When I did the connection swap, the DL connected monitor would power on what looked like a backlight, but not show the desktop until the second monitor (TB) was connected and showed the desktop. Then the DL monitor would flicker and display the desktop. When I swapped the cables back to the "correct" configuration, the same thing happened, but now back to "normal".

Same problem on M2 Macbook Pro, Sonoma 14.3.1
 

Just encountered this problem today, using Dell D6000 docking station. The monitors are on but my Mac is not recognizing them or even connecting to power. I've tried uninstalling and reinstalling DisplayLink, rebooting my machine, flipping the USB-C and using each port. I saw that they are working on a new release aimed for mid-February, but it's still not out yet.

Gave this a try but didn't work for me unfortunately.
