Michael Tressler I have tested this functionality as a dual display configuration. It works.......sort of.
The MTR cannot initiate sharing of Whiteboard, an individual in the meeting needs to share, then select Whiteboard, which is not a big issue.
The Whiteboard appeared on the second monitor which was a touch enabled display and indeed, one could select an ink color and annotate, but that is all one could do.
Since it uses the browser version which is extremely limited. all you can do is ink.
There are a text box and note option which appear in the tools with the ink choices and one can select them on the touch display, but there is no keyboard to type content into them, so it is a point of frustration for users who may select those options and find there is no way to use them.
One is also limited to original canvas size that appears when sharing starts. No ability to add a page or additional content once the screen is full.
One can zoom and scroll to add additional content to the infinite pallet, but the remote participants don't see that, it only shows on the touch display. The reverse is true as well when a remote participant expands the pallet, it does not show on the touch display in the room. Again, a source of frustration for the users when they try to use the available function which does not work.
I will not be implementing as it will be a source of IT service desk tickets from users trying those features and finding they are not functional.
