The PT-EW540 supports a maximum resolution of 1920 x 1200 (WUXGA). That's over seven times the resolution of a 640 x 480 (VGA) data projector, which is the most common resolution supported by comparable spec projectors that were released more than two years ago. 640 x 480 (VGA) is also supported by this Panasonic projector. This Panasonic multimedia projector also supports a supported graphics resolutions of 1280 x 800 (WXGA).
A 1920 x 1200 (WUXGA) supported graphics resolutions is actually the best supported resolution across all 2000:1 contrast ratio projectors that were released around the same time as the PT-EW540.
A 640 x 480 (VGA) supported graphics resolutions is the worst supported resolution across comparable types of projector.
