A:Answer Each monitor comes with one HDMI cable, and so if your computer tower has 2 HDMI connections ports that's all you need. However, if the tower has only one you can either purchase a docking station with at least one HDMI cable connection port (I purchased a j5create SB 3.0 Mini Doc JUD380, which works perfectly with mine). The other choice is to purchase a HDMI to VGA adaptor cable/connector.
Hope this helps you.
