How to Use an Additional Computer as a Secondary Display

Hello again. It is Mike “Cannonball” Kullish back in only my second post, so please be gentle. I was recently working with a customer and they asked me if it was possible to use a Surface Pro or Surface Go as a secondary monitor. I had never thought about this before, so figured I would see if I could figure it out. It only makes sense, right? I promise to keep this article sweet and to the point. (Mostly anyway…)

 

Well, it looks like our friends in the Windows Product Group have our backs. A quick search of Bing, did not provide the results I was looking for, but an email to another very smart PFE led me to a solution. (A big shout-out to Tom Ausburne for filling me in on an easy way to extend or duplicate your primary Windows 10 monitor to another Windows 10 device!) The quick answer is to use the Microsoft “Connect” app that is already installed on Windows 10 devices along with the Project option that shows up in the Windows Notification Center (Win + P). For the example below, I have a Surface Book 2 that I am using as my primary machine, and a Surface Pro 4 that I will use as a secondary display.

 

On the Surface Pro 4:

1. Click on the Windows icon lower left hand corner of the screen

2. Type Connect and verify the application is installed

3. Click to launch the Connect App

On the Surface Book 2:

 

1. As with most Microsoft solutions, we have options. You can either:

     a. Open the Windows Message Center and Project

          Or:

     b. Type Win+P and choose “Connect to a Wireless Display.” (It shows up if you are on the same network.)

     c. Choose the option to Connect to a wireless display:

2. Select the Surface Pro 4 device from above to connect the second monitor

3. You can click Win+P again to choose extend display.

4. Now you have Multimonitor capabilities.

 

My experience so far has been that this solution will work on most any Windows 10 device that supports Miracast, but in lab testing, I only used a Surface Book 2, Surface Go, and Surface Pro 4. I have to admit that I always travel with 2 devices, and this solution has come in handy on more than one occasion while sitting in a hotel working on a customer solution.

 

Thank you very much for reading, and I hope this helps!

It sounds obvious when you write it. But hadn't thought of it until I read it.

 

Thanks!

Just to add a little more information, both devices have to be on the same network, however that network can be Bluetooth.  If you have the secondary device connected to the Primary as a Bluetooth device this will still work just in case you don't have a common network connection handy.  Also you can type [Win + K] to go direct to the Wireless connections instead of having to go to [Win + P] first.  Either will work but I'm all about "efficiency"  :smiling_face_with_smiling_eyes:

So simple. So helpful.

 

Love your work!

This will be fun to try to add my Hyundai 2 in 1 as another display! Thanks!

Just tried to do this with my Surface Book 2 as the remote display, but the Connect app reports that the SB2 doesn't support Miracast! Seriously? The top-of-the-line device doesn't support it? Anyone know if this will be fixed in the near future? Note: I'm using Win 10 Pro, 1903 Build 18362.239 on the SB2. Thanks Craig

Ignore me.  It was the old - Wireless set to 5GHz only.  Resetting to Auto and Miracast works again...

 

If only it worked from a wired desktop...

Copper Contributor

It does work on desktop with wireless adapter. I use my Surface Pro as wireless display for more than a year.

Copper Contributor

You can also use the Wireless display app in the Xbox one store.

Just tried to display my Windows phone on my SB2. Couldn't get it to connect. SB2 acting as remote display. It's not because I'm using a Windows phone as I can connect to other wireless displays with it. It asks for a pin. The logged in SB2 pin doesn't work.

Copper Contributor

I can connect Android phone to SB2

Great procedure, well done. I have enjoyed the comments. I just went to test this from one laptop to another, where the laptop to be displayed is typically accessed from an RDP session. Connections cannot be searched over an RDP session.

hello

is there any way to make it run with low latency?

Microsoft

@asemn I dont know of any special configurations. I would suggest adding that request through the Windows Feedback app.

Copper Contributor

@Michael Kullish  thank you

I had stumbled upon doing this a while back but great to see you put it in a proper post. I shared it to http://linkedin.com/in/imran and http://twitter.com/ImranAnwar too. Regards

I would sugest another way to use the second monitor: like a second desktop (another srart menu, anothers icons, etc.)

Brass Contributor
I've suggested this before, but it would be very handy to connect over Wired Ethernet to smart TVs - almost every client has a big screen in a meeting room, having to find the right cable ( HDMI-HDMI, micro HDMI-HDMI, micro HDMI - DisplayPort, mHDMI-DB15, mHDMI-DVI ) is a right pain. The TV is on the network, lets just connect to it.

mouse whitout borders app is better

Copper Contributor

@nwegah but it does not give you the capabilities of the connect app

Brass Contributor

Does anyone else need to enter a pin for this to connect?

Copper Contributor

@David Jones it depends on your settings.

have you changed the app settings lately?

Brass Contributor

when I go to the settings in the app there is meant to be a list of connections which is empty. I can't return from this. Nothing I can change there.

 

Ps wrt another post here, my smart tv had Chromecast built in according to a screen saver on it but can't see how to use it. It's a TCL Android TV.

Copper Contributor

It`s sounds good ,but the mean can`t used with low configuration computer,the ping is too height between computer.

Brass Contributor

I haven't tried it yet but it should work in principle with Windows 10 IoT-Core as that's supports both ends of Miracasting.

Note say it won't with MS Surface though, and that's all I have to test it with..

Brass Contributor

Thanks for the article. Works great using my Surface Studio 2 as the primary device and my Surface Pro (2017) as the secondary.  I went a bit crazy with the knowledge and confirmed it worked with my Surface Go and Samsung TV as well.  You've created a "monster" @Michael Kullish :lol:

This is cool. I have done this with my Android phone, but not PC to PC. I need to try it with my 'spare' Surface Pro 2, which I keep on the boat.

 

Does anyone know if you can rotate the slave device to portrait and get a full screen that way?

In case you can't find the Connect App on your Windows 10 device - this just happened to me - there is help:

 

  1. Go to your Windows 10 Settings
  2. Select Apps
  3. Under Apps & Features, go to Optional Features
  4. Click Add a Feature
  5. Select the 'Wireless Display' feature

 

Taken from Fix: Install Missing Connect App in Windows 10 [Miracast Wireless Display]

Copper Contributor

The feature is still available, but by Settings > System > Opțional features > Add a feature.

I my case, I had to restart after installation to be able to find "Connect" app, by searching it, in the taskbar.
