My preferred resolution is 3200x1800 on a 27" display. For some reason, the new M2 MacBook Air does not offer this resolution, neither on an LG Ultrafine 5K, nor the Apple Studio Display.

Using an iMac Pro or a MacBook Pro, with either display, gives the 3200x1800 option.

This is true with both Monterey and Ventura. The "Show all resolutions" switch does not help.

I called a senior advisor at Apple and he was stumped.

Is this a hardware limitation of the Air's GPU? Is there any way to get 3200x1800?

Solved, using https://github.com/jhford/screenresolution

Available via brew install screenresolution

screenresolution set 3200x1800x32@60 works on MacBook Air, FTW!

The maximum horizontal resolution of the framebuffer for M1/M2 and M3 is limited to 6144 pixels. On the Max/Pro chips it is limited to 7680 pixels (source).

The scaled resolution is rendered in 4x times and then scaled down to the actual screen size. This means that Mac display adapter offers these maximum horizontal resolutions:

  • 3K HiDPI scaled resolution on M1, M2 and M3 (3072 * 2 <= 6144 horizontal resolution)
  • 4K HiDPI scaled resolution on M* Pro/Max (3840 * 2 <= 7680 horizontal resolution)

If you want to run a higher resolution you'll have to resort to a dummy/mirroring method which can be configured through tools like:
