Is one of the supported resolutions unavailable on an ultrawide or super-ultrawide external display connected to your M1 Mac? If so, Apple wants you to know that not only is it aware of the issue but is also working on a fix for an upcoming macOS release as we speak.
According to a new Apple support document published Sunday, if you connect an external ultrawide or super-ultrawide monitor to your Mac with the Apple M1 chip, certain display resolutions that are supported by the monitor may not be available. “Apple is aware of this issue and resolution is planned for a future macOS update,” the document states.
The Cupertino company did not specify the particular Big Sur update containing a fix for the annoying problem, but one possibility is macOS 11.2, the first beta of which was released for developer testing last week (there’s no word just yet on what’s included in that update).
By default, the Displays preference pane only shows you resolutions that are the most appropriate for your connected display. You can reveal additional resolutions by clicking the System Preferences icon in the Dock and choosing “Displays” in the System Preferences window, then press and hold the Option (⌥) key while you click the button “Scaled”.
