Sharing : Solved M1 limited resolution selection

Ryan0751 · 01-21-2021, 11:59 AM

This is unfortunately not a solution for me.

I am using a MBP 13" M1 with an LG 32UL950-W 4k 32" display.

The display is connected to the MBP using the StarTech USB32DP24K60 USB 3.0 to Dual DisplayPort DisplayLink adapter.

I am able to select 3840x2160, which is too small for my eyes. Or I can drop it down to 1920x1080.

Typically I would use a HiDPI (scaled) setting of 3008x1692 (which appears when the display is connected directly, not via DisplayLink).

Using RDM, I see the same resolution options as other programs of this type (EasyRes, SwitchRes X). I can select alternative resolutions that aren't shown in the macOS system preferences, but they are NOT HiDPI (scaled), and therefore look very fuzzy (unusable for me).

If this can be corrected via software that would be fantastic.
