If your presentation audience is noticing pixels, then projector resolution may be the least of your problems. Nevertheless, Sony's just introduced a new pico module that'll allow manufacturers to build pocket-sized projectors with high-def, 16:9 images using laser beam scanning (1,920 x 720 with rectangular pixels). That'll bring sharp focus regardless of screen distance, along with high contrast, wider color gamut and reduced laser "speckle," according to Sony. There's also built-in screen distortion correction for off-kilter situations. If you're now scheming about some kind of shark-mounted entertainment system, though, it'll have to wait -- the tech is only available to projector makers.
