With UVC 1.4 we allowed our users to use the 1080p mode. In my opinion it is an advantage when you receive a 1080p picture in a multipoint call.
In UVC 3.0 you can also allow 1080p (1920 x 1080) as video format in the group configuration of the Clearsea server. But the Desktop Client (Lifesize Video 9.0.117) seems to be limited to 720p (1280x720). In several tests I never got the 1080p resolution with the new Client.
I want to request to get back the 1080p mode for Clearsea 5/Lifesize Video 9.
