Very new to the RealPresence Groups series

I have 2 Group 300 devices in 2 seperate rooms

From 1 on these devices, when remote user presents a powerpoint, we can see the presentation fine

From the other we cannot

Have done a stare and compare on the configuration of both of the units and do not see any differnce

Any ideas???
