How to Use your Windows 10 PC as a Portable Monitor

1. Preparing your Windows 10 Tablet or Laptop

There are some requirements that both PCs, the main PC, and the wireless display receiver PC need to have in common.

• Both PCs must run Windows 10 with Anniversary Update or more recent.
• Both PCs must be connected to the same network (Local Area Network).
• For better performance, both PCs must support Miracast Protocol.

2. Configuring your Windows 10 Tablet or Laptop as a Wireless Display Receiver

To configure your Windows 10 tablet or laptop as a wireless display receiver do the following.

1. Click on the Action Center icon.
   
2. Click on Connect button.
   
3. Click on Projecting to this PC button.
   
4. It will show up the Projecting to this PC settings page as follows.
   
5. Make sure you selected Available everywhere or Available everywhere on secure networks from the first box.
   
6. Select First time only, if you want to confirm when a connection is being made for the first time.
   
7. If you want to use a PIN for confirmation, you can turn on the Required PIN for pairing.
8. By default, your computer can only be discovered when connected to a power source. If you want it to be discovered anytime, you need to turn off the “This PC can be discovered for projection only when it is plugged in”.

Now everything is all set and done. Your computer is ready for accepting a wireless display connection.

3. Projecting your Main PC to a Configured Windows 10 Wireless Display

Now you can project your main PC to your configured Windows 10 tablet or laptop by:

1. Click on the Action Center icon.
   
2. Click on Connect button.
   
3. It will take some time to look for your computer, once it is found, click on the computer name.
   
4. You will need to confirm the connection for the first time. Do this on your Windows 10 tablet or laptop.
   
5. Once you confirm the projection, it will project your main PC screen to your tablet or laptop just like expected on a common monitor.

4. Enable Remote Mouse, Keyboard, Touch, and Pen Input

The Projecting to this PC feature also allows you to use your tablet’s input to interact with your main PC session. That includes mouse, keyboard, touch, and pen input. To do so:
