@flux_user_55 Windows is reporting it "should" work, but clearly it isn't. Do you know if HDR is turned on? f.lux may not work with it.
Otherwise, the "9621" driver from 2021 for your GPU is pretty old, but it does seem to be the one Microsoft is still shipping - I wonder if they missed something. You can get an update directly from Intel, but usually for Surface it wouldn't be needed.
