Problem: My classroom has a document camera, and nothing is showing on video projector screen.
Answer: If you are using a regular document camera in a classroom, try pressing the VIDEO button on the control panel on the wall. You may need to press it multiple times to cycle through the inputs. If you are using the newer Elmo 4K HD document camera that are in some classrooms, press the "DOC CAM" button on the control panel on the wall.
