Sorry, there was a problem. Please try again later.Display port can be connected to a graphics card that is equipped with a display port output. I prefer this over the HDMI as this is my primary monitor. Display port has a greater potential maximum in terms of frame rate and resolution. If your graphics card only has HDMI than that is fine - in this case the DP does not need to be connected to anything.
Sorry, there was a problem. Please try again later.This monitor includes two HDMI 2.0 ports and one DisplayPort 1.2 port. You can connect a compatible computer to DisplayPort 1.2 through a DisplayPort 1.2 cable to use this monitor as an external display. For more details, we recommend contacting Dell Technical Support for assistance after purchase. They are available on Facebook and Twitter(@Dellcares).
