ALLOW ABILITY TO CHOOSE SUBSET OF LOCAL MONITORS FOR RDP SESSION (FULL SCREEN)

Allow ability to select a subset of current monitors with full screen. Currently can choose all or 1 but cannot choose for instance 2 of 4 (full screen).

But with the below trick and tip, you can select e.g 2 monitors for remote and 2 monitors for your local (with a quad monitor setup).
The key settings are:

use multimon:i:1
selectedmonitors:s:0,1

As of now, selectedmonitors must be set from this file, but use multimon can also be set from the command line or GUI.

To get a list of target monitors, you can use:

mstsc.exe /l

to list current monitorIDs for use in your RDP file, results looking similar to:

Make sure you check the “Use all my monitors forĀ  remote session”, as this will set the use multimon:i:1 in the .rdp file

 

Save your .rdp file to somewhere, as we will then open it in notepad to make some edits. In this example, it’s saved as 2monitor.rdp

For my monitor setup, I have a total of 4 monitors, 2 on top and 2 on the bottom. So when I ran the above command (mstsc.exe /l) you can see the details for my 4 monitors. ID, screen resolution, and position. In my case, my top left monitor is (id:0) and my top right monitor is (id:1).

 

so now we will open the 2monitor.rdp file with Notepad.

  1. look and confirm that the use multimon:i:1 exist in the file, if not then add it.
  2. add the option selectedmonitors:s:0,1 (where 0, 1 are the monitor ID you want to use)
  3. save the file, and close Notepad

 

You should now be able to double-click and open the 2monitor.rdp file with Remote Desktop Connection, enter your credentials and only 2 of your monitor will be used for the remote desktop while you still have 2 for your local PC.
