Every pc accepts my S2721DGFA as S2721DGF now. Even though previously it was DGFA specifically. It even has menu written all over that it is DGFA, not DGF. It is a problem as it creates strange refresh rates, like 165,08Hz. And also tearing is awful. Even more if I try to use G-Sync or FreeSync. Which was never a problem when my monitor was perceived as DGFA by my devices.
