OK I have a problem and if you can help please. I work in a 6th form College and in Media and Film they had projectors for showing films. It was a way back from the screen and gave a nice big picture. Over the summer they installed interactive white boards and moved the projectors closer to the screen. This meant that the throw was decreased and the picture became smaller for the films. I need to have a recomendation of a good projector that will work for the White boards but has an adjustable throw so they can zoom out to make a big picture but still have the projector close to the screen The projector at the mo is a Hitachi CP-X275 (the oldest and 2 others which are newer models) Any help please.
