Projecting to Your PC

Here’s one you didn’t see coming: a feature that lets you send the screen
image from one Windows 10 machine—or even an Android phone—onto
the screen of a second one via Wi-Fi. It’s like connecting a second monitor

without wires (Figure 4-12).

Unfortunately, this trick doesn’t work with all Android phones and
Windows PCs—only relatively new ones that have been designed for

wireless projection.

Here’s the setup. So you don’t lose your mind, let’s suppose you’re going to
sit at a laptop and send its screen image to a tablet—a Surface 4.

On the desktop PC, open → → System → “Projecting to this PC.”
On the Settings screen, here are the choices you have to make:

“Some Windows and Android devices...” “Available everywhere
on secure networks” means you can perform this kind of projection
only on private networks like your home network. “Available

everywhere” means you can use the feature even on public Wi-Fi
networks like hotels and coffee shops, which, of course, isn’t as

secure.

“Ask to project to this PC.” Your choices: “First time only” (after
that, you won’t be asked permission) or “Every time a connection

is requested” (you’ll always be asked).

Require PIN for pairing. As yet another security step, you can

require a four-digit passcode to ensure that only your tablet can
connect to your laptop.

PC Name. You’ll need to know this when you project from the
laptop. (You can take this opportunity to rename the tablet, too—
