This is for the UD-ULTC4K triple 4k docking station.
I know that the HDMI port is supposed to be 30Hz (as opposed to the display ports which are 60hz). But the 4k monitor on HDMI seems way slower than 30hz because the frame rate looks fine when I connect a 1080p monitor to HDMI. Like the framerate for 4k on HDMI is slow that I’m barely able to use it.
Or is this just expected behaviour that 4k monitors on the HDMI port on the dock have a significantly slower frame rate compared to 1080p on the same port?
