The two most common resolutions for projectors are SVGA (800x600) and XGA (1024x768). Higher resolutions like SXGA (1280x1024) will dramatically increase the price you should expect to pay, simply because the quality is outstanding. VGA (640x480) has been used for many years in the past, but is no longer an acceptable resolution and you would be hard-pressed to find modern projectors that support it. XGA is generally thought to be the standard and can accommodate 95 percent of all applications.
