No, it is not possible to connect a DisplayPort (DP) monitor to the HDMI port on this device using an adapter or cable. It is important to note that DisplayPort to HDMI cables are unidirectional and can only transmit signals from a DisplayPort output to an HDMI input. Attempting to connect them in reverse will not enable an HDMI output port, such as those on a dock, to work with a DisplayPort input on a monitor.
