Having a dual or multiple monitor setup can be very helpful in multitasking. Personally, I have a triple monitor setup at my office, which includes my main Surface Book display, an LG 29-inch ultrawide, and a Dell 21.5-inch monitor on either side. This setup allows me to view and work on multiple websites simultaneously, up to six websites side by side, which is particularly useful for research, writing articles, and other tasks that require a lot of screen space.
When I work outside of my office, I also use a portable multiple monitor setup. Although I don’t have a dedicated portable monitor, I have found that my Surface 3 with a built-in kickstand works well as a portable wireless display. This allows me to browse the web and perform most other activities with ease.

Preparing your Surface PCs
Before you continue, make sure your both Surface PCs meet the following requirements:
- Running Windows 11 or Windows 10 (with Anniversary Update or later).
- Connecting to the same wireless network.
- Surface PCs with the Miracast protocol Support. Fortunately, all Surface lineup except the original Surface RT supports these protocols. Click here for detailed Surface support for Miracast.
In this scenario, I will use my Surface Book as the main PC and a Surface 3 as a portable monitor just like the picture above. Let’s get started!
