Users of certain ultra and super cool external monitors report that some resolutions are not available when used with an Apple Mac Silicon M1, but Apple says a fix is coming.
Apple’s Silicon M1 Macs from Apple have changed supported external displays, but now an unknown number of users are reporting problems with limited resolution options.
Specifically, when so-called ultra-wide or superlong displays are connected to the new M1 Macs, macOS Big Sur does not offer the option of using certain resolutions. These monitors are built to display a range of resolutions, but they are simply not listed in the System Preferences, Exhibition panel.
“Apple is aware of this problem,” says the company in a new support document, “and the resolution is planned for a future update of macOS.”
The problem was first identified by MacRumors. Apple has not confirmed when a fix will be released and adds only that “this document will be updated as more information becomes available”.

It is also unclear to what extent the problem is widespread, nor is it affecting just a few monitor brands. The new 13-inch MacBook Pro and M1-based MacBook Air are limited to support only one external monitor, compared to several in their previous versions of Intel.
The new Mac mini has a similar limitation, with only an external monitor allowed via DisplayPort. However, it is possible to run a second monitor outside of the Mac mini via HDMI.
