Sometimes you have only one HDMI port on your computer (typically on a laptop), but need two ports so that you can connect 2 external monitors. You can use a switch splitter or display splitter to have two HDMI ports.
What connections do you need for dual monitors?
The monitors may come with VGA or DVI cables but the HDMI is the standard connection for most office dual monitor setups. The VGA can work easily with a laptop to monitor connection, especially with a Mac. Before you go about setting everything up, position your monitors on your desk.
Can you hook up 2 monitors up to a laptop only using display ports?
It depends on the laptop, the graphics card (or integrated graphics), the graphics drivers, and perhaps the amount of memory available. Some laptops will support two external monitors if you can find a way of plugging them in. For example, you could plug one into an HDMI port and the second into a VGA port.
Why do monitors have two display ports?
