So finally...got mojave installed on my 2018 MBP and now external displays do not work. These cables and dock were working perfectly fine before. Tested on another mbp as well and they work fine.
I tried nvram reset and smc reset...no beans. Also installed the latest displaylink drivers...no beans.
Anyone else experiencing this?
[doublepost=1540018169][/doublepost]Yes, EXACTLY the same problem and have tried everything I can find to solve it - but I can't crack it. I do mean everything! I have an external LG 27UK850 4k monitor that worked perfectly before and now it will not connect to my Mojave iMac. It will connect to a TV tuner or DVD player and function perfecty in HDMI. But Display port and the USBC (the reason I dropped $900Aus on the monitor) has rendered my inverstment a total turkey. V5 of the DisplayLink software won't even load - no matter how many privileges I give it. It shows a proper Certificate from Apple but the splash sceen shows:
"DisplayLinkDriver can't be installed on this disk. is Downgrade"
Come on Apple - what the hell is happenning to you. While your stuff is getting prettier it is getting more and more useless and troublesome with every release.
I NEED functionality, not a dead moniotor because I trusted you. No matter how pretty Mojave is - it doesn't work properly.
I NEED this monotor to work damn it! Digitus Extracus Apple.
