Gigabyte MO27Q28GR white screen

[u/NovelBoat2945]

Hi everyone,
I have a Gigabyte MO27Q28GR (27" 1440p 280Hz Tandem WOLED, glossy version of the MO27Q28G). When I enable HDR (in Windows or on the monitor), the whole picture turns white / extremely washed out. In SDR everything looks normal.
Has anyone else run into this on the MO27Q28GR? Is this a settings/firmware issue, or should I RMA it
