Resolution: measurement of your PC's display in pixels/mirrors. The higher the resolution the greater the definition. Most modern laptops are now XGA or higher. Try to match your PC with the projector to provide greatest clarity.
Technology: LCD or DLP. Both are suitable for all applications within business and educational environment - well suited for computer software packages. DLP provides a smoother appearance with less pixilation - ideal for video and photographic images as well as greater contrast ratios.
Brightness: measured in ANSI lumens. For general use in meeting rooms with standard screens up to 1.8m wide - minimum brightness of 2000+ lumens is recommended. With larger screens use 2500+ lumens. For larger audiences or screens consider output of 2000+ lumens. Projectors within 100-150 lumens of each other will produce similar results.
Contrast ratio: measurement between black and white images projected on screen. The higher the ratio the greater the density of these 2 colours, which give the appearance of higher screen brightness. Look for a projector with the greatest contrast ratio for the specification of the machine required.
Lenses: there are now 'short throw' projectors available which are well suited to situations where projector is ceiling mounted and much closer to screen, thus eliminating shadowing from presenter.
