How did you get 4k output with MacOs 11.4 and Displaylink Manager 1.2?
Neither 1.2 nor 1.3 nor 1.3.1 do work using my M1 MacBook Pro. The Monitor gets connected with 4k/60Hz, but the resolution that I can pick in MacOS is limited to 1080. :confused:

Any ideas?

Anyone test 1.3.1 version?
 

I have installed 1.3.1 on BigSur 11.2.3. Things are working just fine. I'm afraid to update BigSur and loose my 4k monitor.

I have 2.5k and 4k attached to my DisplayLink device. I have 2 additional 4k monitors rotated 90 degrees attached directly to the MacMini M1 via HDMI and USB-C to displayport.

I just don't want anything broken, and restoring from TimeMachine will be annoying.

So can anyone confirm 4K is working with DisplayLink in 11.4 with DisplayLink 1.3.1?

It is not working for me

Updated and it seems OK.
 

I updated my M1 laptop, connected my pluggableUSBC-6950-DP device that was normally connected to my MacMini, and 4K is working on it. Screen rotation still is broken, but that was not supposed to be working. 2.5k and 4k monitors worked.

I did option-click the Scaled radio button to get all modes. Its listed as "low resolution" which is irrelevant to me.

So when I get time I will update my MacMini, and I'm not anticipating any issues.

macOS 11.4 and DisplayLink Manager 1.3.1

Seems to be working with DL 1.4, although I had to select scaled rather than native, and I'm not sure why it says low resolution next to it.

Anyone know?

Low resolution means that HiDPI is not enabled. The result of this is that more than likely the text/lines will be blurry at resolutions other than native. There is the outstanding displaylink feature request to try and get HiDPI on the misisng resolutions above 1920x1080 here.

Thanks.

So if it appears next to what IS the native resolution of the monitor - e.g. 3840 x 2160 - then it doesn't make any real difference. I suspect for this thread, that's good enough for Jazz

I don't recall it managing 60Hz as refresh rate before, only 30Hz, so that's probably good news too.
