There has been a steady flow of technology to schools, and equipping classrooms with projectors, especially at secondary school level, has been a school priority.
Teachers are relying more heavily on classroom projectors at all grade levels. Schools are usually in the market to find the biggest bang for their buck. With budgets always tight, it often comes down to how many more classrooms can we equip, if we go with a classroom projector with less features.
Each year, the performance of projectors designed with classroom use in mind (a large percentage) improves, and the prices manage to fall.
The most common classroom projectors currently being installed in classrooms have XGA or WXGA resolution, and brightness of 2500 to 4000 lumens.
There is both a great deal of interest, and a lot of activity when it comes to interactive projectors in the classroom. Just about every projector company targeting the schools is now offering multiple interactive projectors and often some very different ones.
For installation in the classroom, most of the education focused models will have big sound, at least one 5 watt speaker. 10 watts of audio or more, however is now the norm for projectors targeting the classroom. Most of these projectors have a footprint a bit larger than a standard sheet of paper, and most are less than 5 inches tall. All will have VGA inputs, but most newer models are sporting HDMI, and also USB display. All will have remote controls, but beware of some credit card sized remotes with limited range, that can be a mild nuisance.
