RDP Windows 10

This may be difficult to explain.  If a user in Office A is using a computer with Win 10 Pro with 2 30" monitors, and he is going to be stationed at Office B for a period of time, and needs to RDP in to his computer with the two 30" monitors to run applications that have a USB key, and physically the applications need to be executed from that desktop where both screens are required (3D rendering etc). and now he is remoting in via RDP from Office B - he can then execute the apps and get both screens up from Office B - that has worked before.
My dumb question is this, if we physically remove the monitors from the computer in Office A (because they will be needed in Office B), When the user remotes in to the computer at Office A - will it still allow him access to two screens via RDP because the screen info is saved with the video card, or no. I am thinking it is more of PNP and therefore the only way he can get both screens from Office A, is to have the two monitors physically connected on the computer at Office A and of course 2 at Office B - agreed?

I do believe RDP sessions are "headless" meaning you can connect to a PC even without a monitor installed. We do it all the time when connecting to servers. If you have ever sat at a desktop where someone RDP's into it, the screen will go blank since the remove viewer has taken over.

As for being able to utilize two screens, I know that if you get into the Display tab under the Options in a Remote Desktop Session (before connecting) you can check a box for "use my monitors" and that should adapt it to your own session.


Thanks for the reply - I always use RDP with one monitor or headless, I will have to try to see if you can bring up two monitors at the source, from the remote - if there aren't any monitors physically connected.  Just not sure if you can select two, if there aren't any hooked up!

RDP doesn't care how many monitors you have connected.  In the RDP connection properties you can select to "Use all my monitors for the remote session" and all the monitors at the terminal you're logged in to will display the remote computer PROVIDED the remote computer supports multiple monitor RDP (Windows 7 Pro did not support Multiple Monitor RDP; Windows 10 Pro *I THINK* does)

Why not take the computer to office B as well?


Mstsc /w:width /h:height /v:host
The width and height n pixel resolution will provide the scale f the window, do kit use /f for full screen as commonly it will lock into one screen.
The other option provide scaling: I.e if your diplayes are side by side with 1920x1080
You shoukd doe off /w:3840 /h:1080 to fill both screens.
Side by side double the width. X height.

If you need them one on top of the other, double the height.

Win10 pro supports multimon RDP, yes. Don't use the /w and /h options if you plan to address these monitors as two independent screens.


Thanks for the confirmation and your help!!
