I'm not sure about this change. Is 3840x2160 a standard of some kind?
It is standard 4k (a comment saying that would be nice).
I'll update the commit.
Gerd - do you have any comments on this?
The edid spec also has 4096x2160 and 5120x2160, should we add those too while being at it? Not sure which ones are actually used in practice by monitors ...
These resolutions are used by ultra wide monitors. I don't mind adding them, although I don't have a monitor that supports these resolutions natively for testing.
Also: What about depths other than 32? I think we can safely ignore 24, nothing modern uses that since at least a decade, so it should not be relevant at all for 4k. 16bpp might be useful though.
I think we can add 24 for consistency. Every other resolution in the table has all three modes.
