The LV-7230's native XGA (1024 X 768) resolution, is the perfect resolution match for your laptop computer. (It also supports SXGA resolution (1280 X 1024) through high-quality scaling.) In addition to this performance, the LV-7230 boasts a 380:1 contrast ratio for sharp images and deep, rich colors - even with ambient light. It also features 85% image uniformity for an even image from corner-to-corner. You also get a steady, film-like image from digital TV and high-end DVD players, as the projector's Progressive Scan circuitry converts 480i/575i signals to Progressive. And, of course, none of this advanced technology would matter without the LV-7230's Genuine Canon Optics.
