A:AnswerThis monitor has a VGA connection and an HDMI input.
If you are using just your laptop and need to extend your display, using the HDMI is the simplest way.
My setup uses a docking station and as a 3rd monitor, I have to use the VGA input
A:AnswerConnects easily and well with either VGA or HDMI.
I just added another laptop via a 8-port KVM switch and the new laptop doesn't have a VGA port and neither does the port-replicator (dock). I was able to buy a cheap ($19) VGA-to-USB-C and it connects and looks great!
