Thank you so much for reaching out to us I would be happy to assist! Currently, our uga-4kdp and uga-4khdmi USB 3.0 adapters are not supported with Mac OS, as we have seen performance related issues in regards to the operating system, and how it communicates with the DisplayLink drivers and hardware.

We have been following this particular issue for a fair amount of time, and although DisplayLink does make a driver available, we have marked these DisplayLink devices as incompatible. You can read more about our findings at this link -> I hope this information helps, but please let me know if you have any additional questions or concerns! Thank you for your time, Marc Product Owner & Technical Support.

I try to connect a Samsung external monitor to my new 2017 iMac, but the monitor isn´t being recognized. I used the same monitor with my 2012 Mac mini and it all worked fine (even with two monitors). I use a new USB – C 3.1 to DVI adaptor, but my iMac isn´t recognizing my Samsung monitor. I have just updated to Mac OS High Sierra and it still doesn´t work (it didn`t work with Mac OS Sierra either). And yes, I have opened up system preferences and Displays. Using my Mac mini, the Samsung display showed up in preferences.

Searching the net, it seem to be a problem for many people, but I cannot find a solution. Any suggestions? Hey everyone, I had the same issue, after upgrading to High Sierra my external monitors would only show the mouse and otherwise just be black. I use a wavlink usb3.0 docking station to hook up my monitors and external keyboard and everything.

After spending a stupid amount of time looking through this and other forums and not being able to reset the SMC, I realized there was a really easy solution. UPDATE YOUR DISPLAY DRIVERS AFTER YOU'VE UPDATED TO HIGH SIERRA. If you use a DisplayLink system: otherwise try downloading the newest driver for whatever external display you are using. Hope this helps, otherwise, good luck! Hi, I ran two monitors (and also used my MacBook Air's screen as a third display) through a thunderbolt dock, one using a thunderbolt to DVI adaptor the other a USB to DVI adaptor on Sierra, now with the upgrade only the thunderbolt to DVI monitor works. I have tried changing the monitor, the cables, swapped over to a HDMI to DVI cable which made the HDMI monitor work but stopped the thunderbolt one from working, even changed the dock to a Belkin one (which also used to work in dual screen mode).
