I’m not really familiar with the problem, but it appears that the firmware database for monitors under Linux is not as extensive as the one Microsoft has. If Linux doesn’t have a specific definition for a particular monitor, then it can fall back to querying the monitor. But it is apparently not uncommon for monitors to not report their full list of supported modes over this protocol.
