3840x1080 HiDPI missing with Macbook Pro M4 Pro and Samsung Neo G9

Hi,
I'm trying to get 3840x1080 HiDPI with my Macbook Pro M4 Pro on my Samsung Neo G9 49'
I'm limited to 3360x946 max with BetterDisplay.
i'm connected via a USB C - DP 1.4 cable which support 8K 60Hz
Can someone help me please ?

Sadly this is a limitation on the M4. Here is a discussion about these matters: https://forums.macrumors.com/forums/mac-mini.146/

You can get higher resolutions with virtual screen mirroring.

Even on an M4 Pro ?

Yes. The M4 and M4 Pro is identical in this regard. The M4 has the ability to have 3840px, but due to the dynamic nature of resource allocation it tends to be stingy allocating a large framebuffer as that would prevent additional displays from being connected.

Thanks for your reply
BetterDisplay is a perfect app ;)
