Picking the right resolution Here are some basic guidelines for choosing the right resolution: Pick a resolution that is adequate for your presentation. If you use mostly type presentations, you can save money by going with a lower (SVGA) resolution. If you are, however, presenting information with a lot of numeric data, you may want an XGA resolution. And for highly detailed and technical presentations, sharpoverheadprojectors such as engineering drawings, you may need the higher resolution SXGA projector. Get a projector that matches the native resolution of your computer. If you have a computer with SVGA resolution, then an SVGA projector will give the sharpest and cleanest image. Most of the projectors today can project input signals other than their native resolution, however, there may be a loss of sharpness and detail in the process. If you have a high resolution computer and a matching resolution projector is out of your price range, choose a projector that is one step down in resolution. Projectors convert a different input format to its native output format through a process called "scaling". Some projector are very good at scaling, thus making the fuzziness in the image very minor. The quality of scaling varies among different projectors. ©2003 www.sharp-projectors.com. All rights reserved. |
