It is standard 4k (a comment saying that would be nice).
> 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 ...

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.

take care,
