Nope, we'll have it in the office at all times. It should be fairly portable - we have visiting speakers who like to use their own laptops to connect to the projector.
The room in question is also leased for film and TV shoots - unless the installation is stellar, mgmt does not want any permanent tech installations in the room. It would be best if we could bring out the projector only when needed.
Room can seat 60 people comfortably - lights can be turned off and dimmed. Room has large windows which do not pose a problem - most use of the projector will be during evening hours.
We have a screen - 16x9
I am really not sure on the image size - recommendation?
We set-up usually from 4-30 people at a time. We have a large conference table in the center of the room and then chairs around the outer edges of the space.
16x9 image would be great but may be an overkill?
