USB C can be used as video output like an HDMI port on a laptop or a graphics card. It doesn't have any video RAM of it's own. It is a better quality port than VGA still on some laptops with higher supported resolutions and refresh rates. And depending on the setup this can be better than the HDMI port on the same device. My Mac Mini's HDMI port can only do 4K resolution at 60Hz while the displayport through USB C can do 5K.
