What is the difference among SVGA, XGA and SXGA projectors?
XGA (Extended Graphics Array) projectors have a higher resolution, 1024 x 768 pixels, compared to SVGA projectors, 800 x 600 pixels. This means that XGA projectors produce a clearer, sharper image. SXGA(Super Extended Graphics Array) is a A high-end video standard, with 1280 x 1024 resolution. SVGA resolution projectors are suitable for presenting texts, simple graphics and PowerPoint slides. XGA resolution projectors are suitable for advanced graphics, vidio,spreadsheets and large-screen images. SXGA resolution projectors are suitable for extremely detailed images, such as engineering drawings or CAD.
