These are the necessary conduits that link a computer with a display. Cables come in a variety of interfaces common today, including HDMI, DisplayPort, DVI, and VGA. Various adapters and splitters exist to convert or multiply one connection to another, but it is always beneficial to use a native connection if you can. It is generally recommended to not exceed cable lengths of 3m if you can help it. Scan recommends connecting a PC to a monitor via either HDMI or DisplayPort, and either is needed for a high-resolution 4K display to work at its highest refresh rate.
