Microsoft Teams Rooms (MTR) with Dell Optiplex and dual screens
Hello,
I'm investigating an issue that my company is experiencing. We have a number of Microsoft Teams Room devices, all powered by Dell Optiplex micro desktops and Dell touchscreen displays.
One device in our configuration has two screens and my boss was told that it's possible to have content in meetings duplicated/mirrored on both. We have been unable to achieve this effect so far.
Part of our hardware configuration uses Logitech cameras and audio equipment so we started with Logitech. The Optiplex runs a specialized build of Windows 10 IoT that runs the Teams Room application and the primary UI for this machine is a Logitech Tap, a small touch-enabled tablet that's attached to the Optiplex. The Tap UI contains an option to turn on dual-monitor support as it's disabled by default. This gave us both monitors, but Teams does not duplicate the output. If someone is sharing a PowerPoint file, it's only displayed on one screen while the other shows the meeting participants. The most we can do via the Tap is to swap the screens.
Logitech Support believes the issue might be that a Windows display setting to duplicate might not be honored when the Optiplex reboots to enter the Teams Room. (It has to do this otherwise the Teams Room client won't run.)
I reached out to Dell Support and I was told that this particular question was "out-of-scope" and I can only assume it's beyond the scope of our support agreement for this Optiplex (ProSupport).
I've already posted this tale of woe in a number of other venues outside of Dell's community pages and nobody else seems to be asking this question.
At this point, I think the issue is more with the Teams Room software than any of the hardware we have so this may not even be Dell's problem to fix. But I'm hoping someone here would have some insight or thoughts to share.

I know I'm very late to the reply here but thought I'd contribute since I recently had the same question and it might benefit others who are looking. The Logitech MTR setup does not support multiple screens without the use of a splitter (unless you're using the Rally Plus system). Your primary display is the Tap device and your secondary display is the screen/TV. If you need to add others, use an HDMI splitter between the PC and the screens and it will work.

Thanks for your reply. That's exactly what we did.
But I think there is a potential second method, though I didn't investigate it in depth. (My boss told me I had wasted enough time on this.)
The Dell Teams room devices use Windows 10 IoT, and apparently it defaults to protecting certain write operations to disk. And I think that one of the write operations it's preventing is changing the display settings.
I found that if I log in at the Tap and poke through the desktop, I could configure the two large displays as separate displays. Unfortunately, when the OptiPlex reboots, that change is reverted. I think it's possible to turn off the overwrite protection to save the display change, but I'll leave it to others to find out.
