How to Connect a Monitor to a Surface Pro 7
With the release of the Surface Pro 7, Microsoft replaced the Mini DisplayPort connector with USB-C. Although exact placement depends on the particular Surface Pro model, most feature the USB-C port on the right-hand side of the display. Once you’ve plugged in your external display, it will be immediately detected by your Surface Pro and you can begin using the second display.
How to Connect a Monitor to a Surface Pro 6 or Older
All Surface Pro devices up to and including the Surface Pro 6 use a Mini DisplayPort. The placement of your device’s Mini DisplayPort connector can vary depending on your generation of Surface. Still, it’s typically located on the right-hand side of the display when viewing from the front. Once you’ve plugged in your external display, your Surface Pro should immediately detect it, and you can begin using the second display. It will duplicate your standard Surface display by default, but you can also extend it.
How to Connect Multiple Monitors to a Surface Pro
Although you can drive multiple displays from a single USB-C output using daisy chaining, a much easier way is to use the Microsoft Surface Dock. It’s a small hub compatible with every Surface Pro since the Surface Pro 3, and gives your Surface device a much wider range of more numerous ports. They include four USB-A ports, a 3.5mm headphone jack, a Gigabit Ethernet port, and a pair of Mini DisplayPort outputs. You can then use the additional display(s) as duplicates of your existing screen.
