Multiple monitor support with Remote Desktop Service in Windows 8 Pro


I have discovered, that Windows 7 Pro doesn't support multiple monitor for remote desktop service, as it is featured only for Windows 7 Ultimate and Enterprise editions. See this article

I wonder, if this feature is now supported in Windows 8 Pro or does Remote Desktop work the same way as in Windows 7 Pro ?

I need to connect to my computer using Remote Desktop Client and use extended desktop on multiple monitors.  However current Windows 7 Pro support only desktop spanning ( /span), which is not that useful.

Thanks for your reply.

Hello Niki, 

I am afraid you haven't replied to my question. I am asking about Windows 8 indeed. I would like to know, whether Win8 Pro do support multimonitor terminal service so that I don't have to face the same issues as Windows 7 Pro, that doesn't support it. The article you refer me to, it describes functionality within Win 7 Ultimate and Enteprise.

from my own use experience with windows 8 pro client, multimon nor span is supported.

/span and /multimon parameter are ignored so are the proper lines in the rdp file

edting the rdp session options does not help either.

may be the enterprise version of windows 8 support it. so in this aspect windows 8 pro is a downgrade for me from vista ultimate

Try this, save your RDC shortcut on the desktop, open it in notepad and change the following values (for me it was the first two lines)

screen mode id:i:2
use multimon:i:0


screen mode id:i:1
use multimon:i:1

Save and log in using the shortcut. We had a large issue with this not working at corporate and this was what I came up with.

Hope it works for you!

I know the original post is old, some comments are fairly recent, but if you run (win+R) mstsc /?, it will show you /multimon.  If you run simply "mstsc" or click the "Remote Desktop Connection" icon, click the "Show Options" button, then go to the Display tab.  There is a check box that says "Use all of my monitors for the remote session".

I have tested both Win 8 Pro & Win 8 Ent with the /multimon and it checks that box, and opens RDP sessions across my three monitors.  Also manually checking that box works.

good but does it treat 3 monitors as discreet windows or one big screen?

difference? more desirable to some office workers to put up speci app in one screen, some other in anoter screen always without draggin every time on opening

I have Windows 8 Pro and I can confirm that it supports discrete multiple monitor RDP session. I initiated the RDP session from my other Windows 7 PC by using the following command

mstsc /multimon

Hope this helps for anyone looking for the answer.

That is great but how about having 2 out of 3 monitors enabled for RDP.

Right now I must confirm that configuring multimon locally, or changing max monitors in group policys, or configuring RDP host server on client settings tab regarding max monitors does not work at all.

I see that this is a big issue for many who use 3 monitors. Whatever setting you change, you always will get just one monitor or all three. Clearly it does not work so please no advice how to change these settings.

In stead let us know if it works and if really so... let us know how. Who knows the answer!

Current, I have Windows 7 Ultimate and the client has Windows 7 Pro, the function of /multimon doesn't work.

So if I use Windows 8, the function /multimon will work surely?

This seems to be a really old thread, but I'd like to propose an answer.

The feature that is lacking in Windows 7 Pro is now built into Windows 8 Pro. I have confirmed this by using a windows 7 Pro computer to initiate a remote session into a Windows 8 Pro computer with multiple monitors. Each monitor is it's own and not just spanning one monitor across multiple screens.

You don't even need any of the tags discussed.

  • Open Remote Desktop Connection in Windows 7 Pro
  • Click "Show Options"
  • Go to  Display Tab.
  • Select the checkbox that says "Use all my monitors for the remote session"

Glad Microsoft finally decided to include it in the professional version.

I'm not able to make it happen. Every time I connect to another computer using "remote desktop", it only shows the remote screen on one of my monitor. Even when I use "/multimon". 

What am I missing?

PS: This is from microsoft website: 

Can I use the Remote Desktop app across multiple monitors?

No. You can't see a single remote session on multiple monitors, and the Start screen and apps from the Windows Store (like the Remote Desktop app) can only be opened on one screen at a time, so you can't view more than one session simultaneously.

I have Windows 8.1 and dual monitors (each a different resolution) and run 2 copies of Remote Desktop, one running the current software version and the other the version under test, for side by side testing. After "research" I found this works for me:

right click Remote desktop shortcut

edit with Notepad++

span monitors:i:1
use multimon:i:1
screen mode id:i:1

So awesome! You rock!

Thank you for this... I tried Splitview but it was unstable and caused some dialog boxes to get hidden behind apps.

Old thread, but finding this helped me get multiple monitors.

I'm on my W8.1 Pro tablet connecting to W7 desktop for work. I have a docking station to make my W8.1 tab have it's own display +2 monitors = 3 displays.

None of the multi mon or recoding as multimon or checking "use multiple displays" would work.

Finally I edited the display width and got it to stretch across both screens, then right click the top of the session and choose "smart sizing" to make it all fit.

Thanks everyone for your ideas.
