After update from 10.15.3 to 10.15.4 external displays doesn't work via docking station

Hi,

I'm having the same issue with an Alogic dock after upgrading to 10.15.5 (worked earlier today on a previous version of Catalina), did you end up finding a solution?

I have found no solutions that works for me, looks like we need updates to our graphics card firmware from apple in the next version

Have the same problem , with the same external display ASUS PQ321, No signal

Has any tested to see if the 10.15.5 supplemental updated has fixed this issue for anyone? Hyper Drive asked me to test this solution before they investigate further/

I can also confirm that the 10.15.5 supplemental update has not fixed my issue either

Just to add, the latest update hasn't fixed this for me either - my external monitor works but it is very fuzzy. Frustrating!

reinstalling/updating the DisplayLink drive and manager app solved this issue on my mac

Had the same issue with the most recent upgrade to MacOS Catalina 10.15.6. I guess I have to just wait until they figure it out again?

Someone posted about updating the DisplayLink drivers and manager. That did the trick. All the other fancy stuff that people tried on my MacBook didn't do anything to help.
