Correct.  recent Dell desktop XPS and high end Optiplex onboard video is DP only.  HDMI is being phased out.  You would need a discrete video card that has hdmi port.
Hello, I am considering a purchase of DELL XPS 8950. However, upon checking the specs I discovered there are no HDMI (either 2.1 or 2.0) ports on the motherboard. I suspect if I wanted to connect my PS5 to my system I would connect the PS5 via HDMI to the monitor and connect the XPS 8950 to the HDMI port on the Nvidia RTX video card. Are my assumptions correct? Many thanks in advance for any and all replies.
