Unable to use multiple monitors for RDP Session Windows 10

Question

_{Tuesday, December 19, 2017 3:35 PM}

Greetings,

Lenovo Windows 10 Enterprise Laptop that is on a Laptop Dock with 2 connected monitors. We are trying to get the RDP session to use the 2 monitors however it will only display on 1. We are connecting to a Windows Server 2008 R2 machine. I have verified that "use multimon:i:1" and or "Use all my monitors for the remote session" is selected. I have also tried to use a setting I found in another forum post "span monitors:i:1" which creates a long window but will not go to full screen mode on both monitors so is not a valid solution.

Thanks,

Magoo

Hi Magoo,

Your current method is correct, including:

a. Click “Use all monitors for the remote session” in the client (mstsc.exe) window.

b. Use the “/multimon” switch on the mstsc.exe command line.

c. Add “Use Multimon:i:1” to the RDP file.

If still no help, check this similar case for some ideas.

Besides, try to use Remote Desktop Connection Manager 2.7.

Teemo,

I found the issue. I found that the issue was related to a group policy setting that would restrict the amount of monitors per session. Our policy was set at 2. I could either disable the laptop monitor so the workstation on the dock would only have 2 monitors or as we did just updated the gp setting for more. Thanks for the try though.

Cheers!
