Hi everyone. I work for a college in which we have quite a nice large theatre. Every year we host a week long film festival where we have guest speakers and show films. At the moment it's a standard def projector ceiling mounted, fed by a DVD player/laptop, etc. I really need to find a suitable HD projector that will be great for film watching and will be fed by a Blu Ray player along with the older sources we have. It will also as a secondary use, be showing powerpoint presentations at staff meetings. The projector will be again ceiling mounted and approx 30 feet away from the screen. The screen is the theatre curtain. Any help with this would be much appreciated.
