A:Answer Unfortunately, we do not have a high refresh rate monitor to test with. It may be possible with the HDMI or DP port, those are Plug n Play but will not work with the other stand alone HDMI port (driver base). However, to use the HDMI or DP port, your computer must support "DisplayPort Alt Mode" over USB-C for video out via HDMI. Please refer to the manufacturer of your hardware for more information on your device. If you have any questions regarding the Dock, feel free to contact j5create Technical Support by Live Chat or Email and they will be glad to further assist you. Thank you.
