What is the difference between XGA and SVGA?
The resolution is the accuracy of the image that the projector will cast. Most projectors fall into two categories – SVGA super video graphics array (800 x 600 pixels) or XGA extended graphics array (1024 x 768 pixels). Similarly, most computers output a signal which is either SVGA or XGA. Projectors that are XGA produce a higher resolution than would a SVGA projector. Projectors are capable of projecting input signals other than their native resolutions. For example, you can usually hook up an XGA computer to an SVGA projector. The projector will automatically convert the incoming 1,024 x 768 signal to its native 800 x 600 output. However, there is always a loss of sharpness and detail in the process, so you will end up with a picture that is not quite as sharp as if the incoming signal had been the same format as the projector’s native resolution. This loss of sharpness also happens if you plug an SVGA computer into a higher-resolution XGA projector. You will usually get a decent ima
