Information

Most of today's portable projectors are very easy to use. Resolution is the number of pixels the projector uses to create the image. The more pixels it uses, the "higher" the resolution: SVGA or "800 x 600"; XGA or "1,024 x 768"; SXGA or "1,280 x 1,024"; UXGA or "1,600 x 1,200". The sharpness and clarity on the screen is determined by a projector's resolution.

Lower resolution projectors are much less expensive, and they can produce images that are just as bright and attractive as higher resolution machines.

If your use the projector for "Powerpoint" style graphics, pie charts, graphs, and general business presentation, SVGA resolution is perfect for this kind of work, and the best solution for the money.

If you are often presenting materials like Excel spreadsheets, you will probably be happier with XGA resolution.

if you are projecting engineering drawings or other images of a highly detailed, you will probably need a very high resolution SXGA projector to produce an acceptable image for your purposes.

Remember that the best resolution for your projector is the resolution of the computer you intend to use with it.
