Apple to fix fix issue with Ultrawide displays on Mac M1 in future macOS update

In a new support document, Apple acknowledged that when an external ultra-wide or super-ultra-wide display is connected to a Mac with the M1 chip, some resolutions supported by the display may not currently be available. .

Apple says it is aware of this issue and has a fix for a future macOS update. Apple hasn’t specified exactly when a patch will be available, but the first beta of macOS 11.2 launched last week, so it’s a possibility.

To see additional resolutions for your external display, click the Apple logo in the upper left corner of your Mac, open System Preferences, click Monitors, and hold down the Option key while clicking “Scaling” .

There is a discussion thread on this issue in the MacRumors forums.
