--- Comment #2 from Rémi Bernon rbernon@codeweavers.com --- On Windows the available display modes are mostly dependent on the display drivers and monitor specs, I don't think standards really matter here.
The virtual desktop display mode list was modified based on the testing that went into Proton display mode emulation. That testing showed that multiple games are broken when the screen sizes list gets too long, and although Wine doesn't yet support any kind of resolution limit, it would be good to have at some point.
The default list is pretty much arbitrary, but including more display modes from the host monitors makes it then more likely to contain modes that are a good fit for the physical monitor aspect ratio, instead of a long default list that only contain standard modes but badly suited aspect ratios.
Fwiw we could also consider making that default list configurable.
