Office / business projectors

Office projectors are typically business projectors for use in small to medium size conference rooms. The computer projector will usually be used in conjunction with a laptop or tablet - watching a movie is normally not the primary use. The most common format is 4:3, but newer devices provide a format of 16:10. This also applies for WLAN projectors. With a wireless projector, when reading picture, text or powerpoint files, it is important to ensure that the file sizes are not too big. If the file volume is large, then it is better to use the cable option. The projectors for computers vary in brightness - some can be used only in darkened rooms, brighter projectors are suitable in daylight.
