I just bought a new computer that has an HDMI input and an HDMI output port. I have a 16 camera surveillance system that is connected to my old computer's video card using two VGA cables. The video card has two VGA input ports. I want to use my new computer as my main source for my camera feed. Can one HDMI input port handle 2 VGA cables? My new computer is the Lenovo A530. This computer does not have any VGA input ports. Please help. Thank you.
