Lack of available resolutions on Big Sur M1 Macs

Hi All,

I've been monitoring the various threads while suffering the same symptoms. I have the Mac device listed above (have had it for 3 weeks) connecting to a Kensington DL device. I immediately updated my OS to Big Sur 11.3 before connecting any devices. But I've had the issues everyone describes from the outset (I believe the issue is with the Mac OS and changes associated with it).

If I connect my monitor to the DisplayLink device (via DisplayPort) the resolution drops to 1920 x 1080.

If I connect my monitor straight to the Macbook (DisplayPort to USB-C, the native resolution is 3440 x 1440.

Right now I have Big Sur 11.4 and DL 1.4.0

I've also used HDMI rather than DP, with zero change.

I'm sure it will get sorted eventually, but thought I'd throw my config up for support to review.
