macOS Big Sur - No clamshell mode...

BHedges · 04-27-2021, 03:14 AM

Big Sur 11.3 update and now my previously working in 4k screen LG 27" can now only run in 1920 x 1080 - so I'd say be very careful with the update, backwards step for me, very disappointed.

@KatarzynaKowalczyk is there any update that can be provided on when clamshell mode might be supported for Intel-based Macs on BigSur?

I've just purchased a Dell D6000 and found that it's about as useful as a brick since it doesn't support clamshell mode. Didn't even consider that I'd need to review the fine print in the release notes for a 3rd party driver to find out this limitation that impacts that hardware product.

Hello,

I am wondering this for a long time, is there any reason why you cannot use the MacBook with an open lid? It is another monitor that you can use - like for some less used windows.

Its' not about, why we cannot use, its more about, it was working and now not.

I have bought the dockingstation with the displaylink only because of this.

It was working before Big Sur and now not. I'm having now also high CPU usage with the display link driver 1.3.0. This is just sad.

Works ok for me. No problem at all. Everything latest updates.

As from this link https://support.displaylink.com/know...cos-big-sur-11:

Quote:

Clamshell mode (lid closed) is supported on computers using Apple M1 silicon with external power connected (e.g. Apple macbook power adapter or docking station with charging capability) on macOS Big Sur version 11.1 and later.
Clamshell mode is not supported on Intel-based macbooks, this is under development.

Currently this not working for intel-based macbooks. So your mac has an apple m1 processor?

Anyway, there are currently much more intel-based macbooks out there.
A fix would be more appreciated.
