I purchased a dock a few weeks ago now, and its been fine up until last week.
I have 3 Samsung S24H85 displays, each with a DisplayPort, USB-C and HDMI Connection. Monitor 1 and 2 are on DP, Monitor 3 is on HDMI. I also have a Logitech Keyboard / Mouse dongle and Jabra headset dongle connected.
I have a couple of laptops I use with the dock:
- HP EliteBook 830 G6 (Work Windows 10)
- Lenovo T470 (Personal Windows 10)
- MacBook Pro M1 (Personalm Mac)
Although all three laptops previously did work across all three displays at 60Hz and 2560X1440 I now only get a single display on my Mac and 2 displays (1 and 2, not the HDMI connected display) on Windows.
I have tried removing / reinstalling DisplayLink on my Work Windows laptop to no avail. All the cables seem OK, and I’ve tried unplugging the dock’s power for about 3 minutes which hasn’t worked either.
Does anyone have any ideas? To my knowledge the failure didn’t coincide with a Windows Update and either way I also have issues connecting a Mac too.
