Type-Digital Projectors

Resolution refers to the number of pixels, or dots, the projector uses to create the image on the screen. Keep in mind that the best resolution for your projector is the resolution of the computer you intend to use with it. If you typically use a notebook computer with SVGA resolution, you will want a projector with the same native SVGA resolution in order to get the sharpest and cleanest image. Similarly, if you normally use a computer with XGA output, you will get the best picture from a projector that has XGA as its native resolution. The more pixels, the "higher" the resolution. In general, the higher the resolution, the more the projector will cost. Following are the types resolution available. VGA (Video Graphics Array) 640 x 480, SVGA (Super VGA) 800 x 600, XGA (Extended Graphics Array) 1024 x 768, SXGA (Super XGA) 1280 x 1024 and UXGA (Ultra XGA) 1600 x 1200.
