There are a few more options available here. You can decide whether a connection must be confirmed on the laptop every time you connect or just the first time, and you can set up a PIN to confirm the pairing process. You’re also able to set up the feature so it’s available only when your laptop is plugged in, and you can rename your laptop machine from here too, to make it easier to recognize on the network.
If you don’t see these drop-down menus, you should see a prompt asking if you want to install the wireless projection feature: Just follow the prompts on screen to do this. The feature you want is labeled as Wireless Display and shouldn’t take long to download and install. Once that’s done, go back to the System and Projecting to this PC page, and the options we’ve mentioned above will then be visible.
