What Is a Dell Wireless Monitor?

A Dell wireless monitor lets you display your Windows laptop, Android smartphone, or tablet screen on the monitor, without using any cables. It uses Miracast and Wi-Fi Direct to create a direct wireless connection between your device and the monitor.

Once you're connected, you can plug a keyboard and mouse into the monitor and use them to control your laptop, smartphone, or tablet from your desk.

You can also connect two devices at the same time using a feature called Dual Cast. This displays a Windows laptop in full screen and an Android smartphone or tablet as a smaller overlay window, both on the same monitor.

Note: Apple iPhones, iPads, and MacBooks aren't supported. Sony smartphones aren't supported as a secondary device for Dual Cast.
