We have a number of hybrid tablet/laptop devices (Dell Venue Pro 11) running Windows 8.1
The Service Desk guys are having issues with remote control.

It is only showing part of the screen and no scroll bars are available.

I *think the issue is that the desktop geometry is being misreported... As per most tablets these things actually run at 1920x1080, yet the Remote Control/VNC Connection information reports Desktop Geometry of 1280x720.

We have tried basic fiddling with Connection Display options (scaling, etc.) but no joy. Is there a way to force or re-assess the actual desktop geometry? We have another 125 of these things coming in soon...!
