How does one setup a custom 1 to 1 resolution?

[george-tims]

Hi, I have a custom monitor resolution 2880x2880 px 30 fps and 3840x3840 30 fps.
MacBook sees them only as 1920x1200 or 1920x1080 monitor...
How would you setup this with BetterDisplay?

How did you set up the custom resolution? What is the actual native resolution of the display? Can you show me a screenshot or export the Display Information... from the display's settings tab?

Hi, I'm using Megawell PCI capture card or Datapath PCI capture on the receiving media machine, which is running Linux.
This capture card is recognized under Windows as a 2880x2880 square monitor right away. Or by setting Custom Resolution display in nVidia Console.
Don't have this media machine with me at the moment, but surely can forward around Monday!

If you need to configure it with a custom timing in the nVidia console, then you'd need to do the same in macOS. You can try getting the display's EDID via the app, add a 2880x2880 timing using an EDID editor app like the free AW EDID Editor (the one that works with nVidia) and then configure the updated EDID as an EDID override in the app.

It actually worked. Just created a custom file in simplified mode. Let me test it under load and with higher resolutions. Thank you!
