[PATCH 2/2] drm: mark MSI MAG273R with the EDID_QUIRK_IGNORE_STEREO_FLAG quirk

From: Michał Szolc

Date: Thu Jul 23 2026 - 18:24:01 EST


This monitor incorrectly marks it's 1920x1080 144hz mode as stereo,
which makes 144hz unavailable. Adding this quirk makes the EDID parser
accept that mode which makes 144hz work as intended.
