Disable remote PC showing logon screen when connected using Microsoft Remote Desktop iPhone app?

Question

I have a desktop PC running Windows 8.1 which I can successfully connect to from my iPhone using the Microsoft Remote Desktop app. The problem is that, when connected, the PC shows the logon screen, and if I try logging on directly on the PC my iPhone is disconnected.
I think this is known as 'curtain mode' in Google's similar Chrome Remote Desktop app.
The same session is shown on both, but not at the same time if that makes sense - e.g. I can open stuff on my iPhone, disconnect and logon directly on the PC and see the stuff I just opened. But I want to be able to view the computer on both the monitor and the iPhone as the PC is in my room and I want to be able to watch TV programmes, etc. without having to get up to change volume, etc.
In the past I've used TeamViewer which has been fine but I already have the Microsoft RD app on my phone and I'm trying to avoid unnecessarily installing more apps.

Is it possible to do this using Microsoft's RDP or will I have to use a third-party app such as TeamViewer or VNC?

Answer 1

Use a 3rd Party app - RDP is behaving as intended; only one user can be logged to any given session, logging from any other location will, as you discovered, terminate any other session.
