setup:
MBP 2016 15 inch with OLED
OS Sierra 10.12.6
USB-C Triple Docking Display UD-ULTCDL (purchased Dec 2016)
DisplayLink driver v. 82262
using all 3 monitors (4k HDMI, 2k HDMI, and DVI)
I’ve been using all 3 monitors (4 in total including MBP screen itself) since December 2016 without any issues until yesterday. DVI attached monitor stopped working. MBP does show all 3 monitors as being plugged in, but DVI connected monitor stays black. I did not do any upgrades that day (OS or other software)
I have attempted to resolve in the following ways, none were successful.
-
Full shutdown/restart of both the computer and the dock quite a few times, and usually waited 10 minutes to replug in the dock to be sure it fully shutdown/reset. Unplugged and replugged all peripherals attached to the dock as well just to be sure
-
Replaced DVI cord with new DVI cord
-
Tested monitor itself by plugging in one of the HDMI cords, display worked fine
-
Plugged the DVI cord into one of the other monitors that was working with HDMI plug, and that monitor did not work.
-
Uninstalled driver v.82262 and installed latest driver v.85514, did not fix (I have gone back to the original driver that was displaying to all 3 monitors).
So, it seems like even though MBP is sensing the DVI connection, the DisplayLink Adapter isn’t sending an actual video signal anymore. Again to be clear, I didn’t recently upgrade anything, as far as I can tell nothing changed to cause the DVI signal to all of a sudden stop working. I’m definitely aware of the history with this dock having issues with OS Sierra but for 9 months it was working great for me.
Anyone have same issue where DVI connection/signal stopped working? Thanks up front for any help/suggestions!
