Ah, the 4x3mm mode is coming from the EDID in bytes 0x42 and 0x43 (offset 0c and 0d from 0x36).
The monitor claims to be EDID version 1.0. It appears likely that instead of a "detailed timing description", this Logix monitor contains a "manufacturer specific monitor descriptor" in bytes 36h-47h.
Further info see page 9 of the following:-

Perhaps the driver should ignore "detailed timings" for early EDID versions, or at least do a sanity check first.
The nv driver must handle this situation differently somehow.

Regards.
