We've been using google hangouts for a few weeks now for video conferencing with a colleague who lives on the east coast. Every time we video her, she sees two screens, which are different angles of our conference room on the west coast. The camera we are using never had this issue before and it's just a webcam that you plug into a USB port. How do we prevent this split screen so she just sees one screen of the group? Is it something on her end?
