Windows 10: Multimon on RDP

Hi dear community!I'm trying to solve the problem with using multiple 2 in my case monitors via Windows RDP.https://techcommunity.microsoft.com/t5/security-compliance-and-identity/using-multiple-monitors-in-remote-desktop-session/ba-p/246840I already visit this link but it does not help. Lets talk about what the problem is. I use my PC for programming purposes, but I have not opportunity to use it directly that's why I use my laptop and connect to my PC via RDP through the same Wi-Fi. Also I use my Samsung TV as a second monitor connected via HDMI. And when I connect to PC directly both

Hi Nikki,

We can see here that you are having issues using (RDP) Remote Desktop Protocol on your computer. There are several reasons why you are experiencing this concern. To set your expectation, we will be doing some troubleshooting steps to isolate
this problem. Before we proceed, may we know the following:

• Any changes made on the computer prior to this concern?
• What troubleshooting steps have you tried so far?
• Is this the first time that you encountered this problem?
• When did you notice about this issue?
• Can you send us a screenshot with the error message that you are getting? Note: Please do not include any personal information.

• Any changes made on the computer prior to this concern?
  
  Initially when we received the problem there wasn't any changes made on the computer since we couldn't figure out the problem, we upgraded the pc to windows 10. It fixed the problem momentarily and then it starts again. Then we re initiated the upgrade the
  same day I wrote this post and it was fixed again and then on today the issue is back

• What troubleshooting steps have you tried so far?
  
  In the past we would delete the MS Licensing Protocol folder as suggested by so many other posts and restart the RDP connection ad administrator to rebuild it. This time around it didn't fix anything. Like I said previously we've tried to upgrade the PC and
  the fix is temporal

• Is this the first time that you encountered this problem? No

• When did you notice about this issue? I'm not sure when it started because I haven't been on this project that long but I would say within the last month based on me. Based on other conversations this has happened in the past.

• Can you send us a screenshot with the error message that you are getting? Note: Please do not include any personal information.
  
  Sure
  
  

 

RDP settings for multi-monitor set up to use subset of monitors for RDP session

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 3 (full screen).
That seems useful, I wish it did that. I know about this checkbox that says "Use all my monitors" but I can't say just use 1 and 2 but not 3, right?

Turns out that you CAN span n monitors but it's just buried/internal and has no UI.
Save your RDP file, and open it in Notepad. Everyone's RDP file is different but yours may look like this:
full address:s:x.x.x.x:3389
prompt for credentials:i:1
administrative session:i:1
screen mode id:i:2
span monitors:i:1
use multimon:i:1
selectedmonitors:s:0,1
I can put on selectedmonitors:s:x,y and then use the zero-based numbers to indicate my monitors. To get a list of monitors, I can run mstsc /l to LIST out all my monitors on my machine. I can also use mstsc /multimon as a command line to use multiple monitors.

So I set my selectedmonitors:s:0,1 to use my left and middle monitor and skip my right one.
