1.What's the model of your HP all in one computer? for example HP 66 Pro G2
2.Did you try to unplug and plug-in the monitor VGA/DP/HDMI cable to your HP all-in-one computer?
3."I have a remote desktop app "
Do you use rdp file to remote access the remote server?
4.Did you try to update display card driver on your local problematical computer?
5.Could you please enter winver in command prompt on remote computer to look the OS version?
6.If we open "Remote desktop connection" app and set "use all my monitors for the remote session" like below picture, then enter the remote computer ip/FQDN, will the same issue happen?
7.What's the resolution about both monitors (HP all-in-one monitor and Acer monitor)?
8.Are you administrator of remote server?
Using Multiple Monitors with Windows Remote Desktop
How to use dual monitors with remote desktop [Windows 10/11]
- Knowing how to use dual monitors with a remote desktop on Windows 10 can come in handy.
- For best experience, we suggest using a reliable and easy to use third-party software.
- You can use multiple monitors with Remote Desktop simply by adjusting couple of settings.
- If multiple monitors are not working with Remote Desktop, solutions from this guide should help.
Nowadays, you can use your home PC from anywhere, thanks to the built-in remote desktop feature on Windows that allows you to control your PC remotely.
Through the Windows Remote Desktop, you can connect to your computer from another location, allowing you to see that computer’s desktop and interact with it as if it were in front of you.
Users who have more than one monitor can also use programs to customize their desktops and make quality-of-life changes.
Accessing multiple monitors during an RDP session
A quick note before we start: Sadly, with the standard Windows Remote Desktop app, you can’t change your connection properties mid-session. So for any adjustments to take effect, you’ll have to terminate all on-going RDP connections.
Ok, without further due, here are the instructions for all three ways to enable multi-monitor support for the Windows Remote Desktop application on your RDC server:
1. Type ‘remote connection’ into the system search box to launch the app.
2. Enter your authentication credentials, then click the Show Options button in the bottom-right corner:
3. Now, go to the Display tab and tick the ‘Use all my monitors for the remote session’ checkbox (DO NOT click the connect button, we have some more settings to tweak with):
4. Go back to the General tab and click the Save as… button, so you won’t have to repeat all these steps every time you need to access this machine from remote PCs. Also, it’s a very good idea to remember or write down the folder you save the ROP file to as you may need to make some adjustments to it later (e.g., to make one of your monitors invisible from remote desktops).
Press Win+R on your keyboard to involve the Run window and type: mstsc.exe /multimon. The “Use all my monitors for the remote session” box will be checked automatically, but for this time only. Neither the connection properties nor your credentials will be saved on this machine. So if you plan to have more remote desktop sessions here, or this is one of your RDP servers, better go for one of the other two methods.
Open your RDP file (by default, it’s in system32) with the Notepad or drag-and=drop it to the browser window, and add the line to it as follows:
On top of that, you can add another string here to hide some of your monitors so that they won’t be visible over TCP from any remote machine:
Replace x1…16 with the actual numbers of the monitors you have. The first number indicates the primary monitor.
Important note: The display’s number is not necessarily the
same one you’ll see in your system monitor properties. To
obtain the correct ones, use the mstsc/l command.
Don’t forget to save the file before closing.
All three methods I’ve just described will also work for Linux and iOS machines, given that you have the correct Remote Desktop versions installed there too. But you should note that all the methods described above only apply to the standard RDP app. The newer black-interfaced one you can get from the Microsoft store has no multi-monitor support whatsoever.
Remote Desktop Multiple Monitors Windows 10
Before you can remote desktop using multiple monitors on windows, there are few things that come into play for you to be able to use dual monitors in RDP sessions on Windows 10.
You want to make sure that Windows is detecting your second screen, if it’s just black or gives you the prompt Didn’t detect another display, you will have to troubleshoot that first.
So, I am assuming that you have the following setup:
- You have a computer in a remote location that has two monitors connected to it
- Have dual monitor setup at home (or wherever you are trying to connect to the remote computer from)
- You are trying to remotely connect to the remote computer using RDP client and use both of your monitors as you would on your local computer
- If your scenario is different reach out to me in the comments
1. Remote Desktop Dual Monitors In Windows 10
Once you are sure that the remote computer supports multiple monitors in an RDP connection, let’s see how it is done.
Using this method you will use two monitors for the remote desktop session. The remote session will automatically expand to both of your screens.
- Go to “Start” or press the Windows key on your keyboard
- Search for “RDS” or simply type in
“Remote Desktop Connection”
IIRC win 7 pro doesn't support multiple RDP monitors. That's a ultimate/Enterprise feature I believe.

That was one thing I thought of. However the other users are using the same version of win 7 pro and the multi monitor feature is working.

I have a client that needs to work from home, so we setup an openVPN to get her into the network. She has an HP 14-dq0011dx laptop ((running windows 10 home) and an AOC e1659fwu secondary monitor.
I've set up her connection to her office computer over MSTSC. The "Use all my monitors for the remote session" button is selected. However once she connects and authenticates it will only display on one screen. Also made sure the slider for full screen is all the way to the right.(office PC windows 7 pro)
I have ran all windows updates and get the latest drivers for the AOC monitor since its a USB monitor. Even had her plug the laptop into her TV over HDMI and the same thing happens, still just shows up on one screen.
From command line i've tried mstsc.exe /multimon with no luck.
I've pretty much ran out of ideas on this. Any ideas of things to try or any thoughts on this would be appreciated.
Hi, it's actually /span that you want.
What version of mstsc you have there? Check by right click on the mstsc's top left icon and select help/about
Try setting the monitor as primary display - any change?

One of the things you may try if the multiple monitor options is enabled in RDP settings but still no monitor is to ensure that the two monitors on the remote side are of the same size/resolution as the ones you're connecting from.
Might make all the difference.
As a workaround, try connecting in a windowed mode and then strecthing the remote desktop window to the size of your local desktop.
If you're feeling up to it, you can always tinker with the registry directly (at your own risk).

Is the AOC set to "extend desktop"? Stupid question, but i didn't see that mentioned.
· · ·
My mistake, The other user is remoting into a windows 10 pro computer.
That may actually be the problem.
The second screen is set to extended.
I will give"/span" a try.
Hopefully this will push them to upgrade,hopefully replace that computer with windows 10 pro.
Thank you all for your help!

I have exactly the same problem (laptop is windows 10 enterprise and remoting in to windows 7. How did you solve? Thanks so much
