Hi,

Bought myself a DL-6950 StarTech adapter (USBA2DPGB) so I could drive both of my screens. However, my second display does not seem to output 120fps when in extended mode, no matter if I have it set to 120Hz or 144Hz, but when I set it to mirroring, it does 120fps fine.

Is this a known issue? What can I do to fix it? For reference: I am using a Late 2020 M1 Macbook Air and a StarTech USBA2DPGB (DL-6950) adapter. My monitors are VX2758-2KP-MHD, and I have this issue on both 1.5 and 1.6 BETA drivers.
