DisplayPort a new generation interface
DisplayPort is a new generation AV interface developed by the display industry for a wide range of tablets, notebooks and desktop computers as well as monitors. It is administered by the Video Electronics Standards Association (VESA).
DisplayPort products, such as projectors and display screens, currently support up to 4K video, and the release of DisplayPort 1.3 enables higher resolution including 5K monitors (5120x2880), using a single cable. DisplayPort 1.4 features Display Stream Compression 1.2 transport, Forward Error Correction, enhanced display resolution (e.g., 8Kp60Hz HDR deep color) and expanded audio transport capabilities.

Professional projectors may include all or some of the following inputs:
VGA was the standard monitor cable for connecting your computer to a monitor or projector. Available on some models but most now have HDMI.
HDMI (High Definition Multimedia Interface) for transferring uncompressed digital data (audio and video). HDMI connects digital audio/video sources such as Blu-ray players.
DVI (Digital Video Input) Some projectors have DVI ports into the computer's DVI port. DVI-D carries a digital signal.
USB (Universal serial bus) Use a USB memory stick for PC-free presentations.
RJ-45 is a network connection that allows the image on the computer to be sent to the projector on the local area network (LAN).
OPS-Slot (Open Pluggable Specification) on a projector or monitor allows you insert a slot-in PC, ideal for digital signage presentations.
