Default Big Sur 11.4 / now not recognizing display

My mac is no longer recognizing the display after the Big Sur 11.4 upgrade yesterday. The display will flicker with the logo and go to black, I've tried the most recent driver and my mac is not recognizing that an external display is plugged in. Any clues on how to fix and troubleshoot this please?

Having a similar issue. No display detected for my monitors since the upgrade.

One of my monitors is being detected, the second is not. I've tried uninstalling/reinstalling DisplayLink. BigSur is up to date

Any fixes work for you guys? I'm in the exact same boat, the DisplayLink device still detects my keyboard and mouse no problem but the monitors are not detected.

Default Same Problem

I just bought the USB32HDVGA USB 3.0 to VGA and HDMI for my 2017 MacBook Pro 13in. I am running the latest Big Sur OS. The symptoms above match my issues. Neither monitor is recognized in the DisplayLink menu. I have not been asked to allow screen recording yet (after installing, plugging in the adapter, restarting, repeating). I was not previously on a version that worked as I just got it in the mail today.

It does not appear that your adapter is a Displaylink Adapter. The specifications do not state anything about DisplayLink and there is no DisplayLink logo displayed on the product. This explains why the drivers do not see the chipset in the adapter.

Dear users,

In order to properly analyze your issues, please follow my recommendations from my 1st post in this topic.

Without log files and more elaborated description of the issue we are unable to follow it and look for resolution.

Kind regards,
Jakub
