ASUS Monitor has limited functionality
I recently purchased an ASUS VA32UQ monitor to use with a 2017 MBP.
When I use the monitor over HDMI, I can easily change the monitors settings via the settings toggle on the right hand side of the monitor, though I can only use the monitor at 4k 30fps.
When I use the monitor over a usb-c to displayport cable, I'm locked out of most of the monitor's settings, and can no longer adjust brightness or other basic functions, though I can use the monitor at 4k 60fps.
Does anyone know why I can no longer adjust the monitor's brightness when using a usb-c to displayport cable / what I can do to fix it?
