1 HDMI, 1 Display Port, and 1 VGA port. My laptop with this Hub, now supports my two external monitors running in extended display mode as well as my laptop screen. Its also good to know I could add even an additonal monitor if needed. I connected the HDMI port to my 4K TV and verified that it does support the 4K resolution..
