Can Mini Mac M1 HDMI port display 3008 x 1692 resolution?

Go to Apple > System Preferences > Displays > Display tab > hold the Alt (option) key and click on the Scaled button.

Or optionally you can try Display Menu.

It's a scaled resolution. The monitor is 4k. On previous macs, it's the middle of the 5 scaling options.

However, that's not possible on M1 Macs via HDMI, so now your interface is either too huge or too small.

...or to put it differently:

Intel Macs support among others 1x, 1.5x 1.75x and 2x.

M1 Macs via HDMI only support 1x 1.5x and 2x *

*and also some really large ones that aren't worth mentioning

I have two identical 4k monitors. The one connected via an USB-C to HDMI adapter supports more scaling options than the one connected via HDMI.

No, that doesn't work. The 3008x1692 resolution isn't available in the System Preferences for monitors connected to HDMI.

Display Menu does support it, but only blurred.

Curious. What device has this unique display resolution? It is not one that I can find a description for.

You did not mention what Display you have?

Try changing the Aspect Ratio of the Display and then choose the best resolution in the macOS Display Preferences.
