Teams Rooms - Newest version causing issues with device certification?

Anonymous

After updating a some HP Conferencing units to Teams Rooms 4.19.57.0, I get an error:

"Microsoft Teams Room device isn't certified.

You must insert the HDMI adaptor that came with this device. If you continue to have problems, contact your organisation's admin or IT support desk."

These systems worked perfectly well on the 4.18 versions.

I have tried with & without the HDMI adaptor.

Is there a way to downgrade Teams Rooms versions at all? I've tried "Reset this PC" multiple times but it only seems to re-install the 4.19 version.

    Unfortunately there aren't any achives for previous versions:

    This link should take you to 4.19.82.0:

    You will need to stop the automatic updates if you want it to stay on this version

    Just connecting a touchpanel, in this case a Logitech TAP solved it.

    I´ve seen the same problem with Yealink and that got solved by connecting a Mtouch panel.

    Done that as well with no luck. Last thing I can realistically try until Microsoft push out an update is to reinstall the DisplayPort drivers when I’m next there on site.

    The Lenovo touchscreen controller that comes with it is connected and working as it should be. We have 2 x other identical setups and those 2 are working ok.
