Odyssey Neo G95NC scaling

[Jens1985]

Hello,
I have an Odyssey Neo G95NC (57") and am trying to run it with HiDPI resolution 6400x1800.
Mac OS only gives me the following two options:

• 3840x1080 - The UI is too big
• 7680x2160 - The UI is too small

I would like to have a third option. If I create my own scaled resolution with BetterDisplay (6400x1800), it tells me that this is already available as LoDPI. How do I get this resolution stored as HiDPI with Better Display?
