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, 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.

Resolution can be defined as the number of pixels used by the projector to create an image. The higher the resolution, the better sharpness and clarity of the picture on the screen. Usually quoted in two numbers, (1024 x 768) The first number represents the number of pixels across the screen. The second number represents the number of pixels from top to bottom. The different types of resolutions are as follows: Resolution Pixels Comments VGA 640 x 480 The lowest resolution and the least expensive. SVGA 800 x 600 Many laptops are SVGA resolution, thus making SVGA a popular choice. XGA 1024 x 768 With new products coming out in XGA, this resolution is the second most popular. XGA projectors tend to be more expensive than SVGA projector but prices are dropping due to the increased use of XGA laptop computers. SXGA 1280 x 1024 SXGA products are geared towards high-end personal computers and low end workstations. They are often used in situations where acute resolution of small details is needed. UXGA 1600 x 1200 UXGA is aimed at workstation applications with very high resolution. There are not very many products that have UXGA native resolution.

is designed for portable use as well as fixed installation. There is an adequate handle that folds into the side of the unit and becomes almost invisible when not in use. Yes, it is three pounds heavier than the, but if you need to put 2000 ANSI lumens on the screen, three extra pounds is not much to complain about. Activating the focus control puts an inadequate little target up in the middle of the screen, and if you don''t find the plus/minus buttons on the control panel or remote right away, it disappears. The focus control leaves something to be desired. One must toggle back and forth almost constantly just to keep the focus function active and on the screen. The target is so small that it takes several passes through the sweet spot to find the ideal setting. In future products, we would like to see a little more thought put into focusing control. produces a very bright image with a gorgeous color palate. The soft array of colors in was rendered as beautifully as any digital projector we''ve ever seen in this price range. The vibrant colors in were reproduced with accuracy and balance.
