So, I'm using a Wacom Link Plus I had lying around to test if I could use it to connect my MacBook Pro 2015 to a Lenovo P44W Monitor/Dock through USB-C.

If I use the HDMI connection from the computer to the Wacom device, everything works fine on the Lenovo: it uses the full native resolution 3840x1200 at 60hz fine.

If I try to do the same with a mDP to mDP cable, I get image for a second and then my monitor goes blank. It doesn't react to pushing any button (except power).

If I use mDP to mDP with a lower resolution i.e. activating the monitor 2 in 1 mode it will present itself to the Mac as a 1920x1200, it also works ok.

Being able to use mDP instead of HDMI would be great as the connector is placed on the MacBook in a much more convenient place for me, so I'm trying to figure out what can be causing this, but I have no clue. Any help appreciated.

No, a mDP cable I had lying around. Running Sonoma.
Possibly a low quality mDP cable... If running Sonoma then you must be using Open Core. Which version of OCLP?

In Somoma, have you tried --
Settings > Displays > Advanced button > Show resolutions as list (toggle on) .. then back in the main Settings > Display page, slide the Show all resolutions toggle to on. Do you see your desired resolution?

No, I don’t see the resolution if I do that, but I see it in BetterDisplay?

I have other cable on the way to discard that. It is probably that and I’m just overthinking this.
