Brightness

An important consideration dependent on the type of venue. It is measured in ANSI Lumens. In short, the higher the Lumens, the brighter the projector, but they can be larger and heavier.

Resolution

Related to the resolution of the computer, determining the sharpness and clarity of the picture once projected. The higher the resolution, the better the picture.
The most popular resolutions are SVGA (800 x 600) and XGA (1024 x 768). Ideally the projector should have the same native resolution as the resolution in use on the computer.

Lamp life

Lamps will need replacing occasionally, making the number of standard lamp hours and the cost of a replacement important considerations. Many projectors have a standard lamp life of 2,000 hours with economy modes extending this to 3 or 4,000.

Size and weight

These are key factors when considering what it will be used for. A smaller, lighter projector will obviously be more suited for portable use, however such projectors often command a higher price and the standard of resolution and brightness may be lower.

Warranty

Most projectors come with a warranty, but it is worth checking that the details meet your school’s needs.
