No 4k on Mac OS 11.3 (M1)
After upgrading to macOS 11.3 i cannot select a 4k resolution for my DisplayLink connected screen anymore. Before the update it worked well.

Hi am experiencing the same, before the update it was working perfectly (smooth @4k).
It broke with the update to BigSur 11.13 and now the best I can get is 1080p. |

I am using a resolution switcher (RDM - https://github.com/avibrazil/RDM) which gives me a workaround for the missing resolutions (but no HiDPI > 1080).
Works fine on a MacBook Air M1 with LG 4k Monitor connected via DisplayLink Dock. Last edited by JanB; 04-27-2021 at 02:36 PM. |

Rollback
Any thoughts of rolling back the OS Update? Having a 4K monitor is more important that any new feature in 11.3. As a work around until DisplayLink Supports 4K again for 11.3

I read that if you use Time machine to restore, it does not restore OS updates. I'm relatively new to Mac so not sure how true that is. I did a restore from yesterday (before I updated to 11.3) and I am still running 11.3. It did not roll back my OS update.
