Hi Everyone,
I purchased a Pro license just to test out something working but it doesn't appear to.
I have 3 monitors
1) Dell U2715H
2) Dell U2715H
3) Dell U2715H
All at 2560 x 1440.
Gfx Card: Intel HD Graphcs P530
I've tried following this guide: https://www.displayfusion.com/Discussions/View/splitting-a-spanned-remote-desktop-rdp-session/?ID=5b1675da-85f6-4994-9255-d453b2c78ff3
But adapting it slightly as I have 3 and not 2 monitors. I do think I got this to work, but the RDP window still spanned across my 3 monitors and didn't do as I thought/hoped it would do and give me back the 3rd monitor to the host machine (outside of RDP).
I'm remoting into a Virtual Machine running in Hyper V on the same computer.
I've tried disabling the 3rd monitor within DisplayFusion but I get the following error:
An error has occurred while applying your new Monitor configuration.
Please check your settings and try again.
Error: Failed to call SetDisplayConfig. [HR: 5]
I wonder if this is because I'm in an RDP session, as I know you can't adjust display settings nativity while in RDP via Windows control panel either.
Any help or other suggestions to do what I need would be greatly appreciated.
Thanks,
Michael
DisplayFusion can't change the monitor settings in the RDP session, but using the guide you linked, you can do what you're looking for by using the following command instead of mstsc /span:
mstsc.exe /w: /h:
So, if your 2 monitors were 1920x1080, you can do this:
mstsc.exe /w:3840 /h:1080
The actual values will be slightly lower because of the taskbar, and the window borders, so maybe something like this:
mstsc.exe /w:3800 /h:1000
You can then do the steps in the rest of the guide still to split that window in 2.
Hope that helps!
