The Epson PowerLite 535W supports a maximum resolution of 1600 x 1200 (UXGA). That's over six times the resolution of the most common graphics resolution of 640 x 480 (VGA) (which is also supported by this Epson projector). In addition, this projector support graphics resolutions of 1280 x 960, 1024 x 768 (XGA), 1152 x 864 (XGA+), 1280 x 1024 (SXGA), 1360 x 768 (WXGA), 1400 x 1050 (SXGA+) and 1440 x 900 (WXGA+) and 800 x 600 (SVGA).
A 1600 x 1200 (UXGA) graphics resolution is in fact the best supported resolution across all data projectors of this type and age.
A 640 x 480 (VGA) graphics resolution is the worst supported resolution amongst similar types of multimedia projector.
