  • Occasional 'rainbow effect' typical of single-chip DLP projectors

Verdict

The Optoma ML750ST is an ultra-portable, palm-sized DLP LED projector weighing only 420g, designed for high mobility and short-throw performance. It features a native WXGA resolution (1280 x 800), 800 LED lumens of brightness (roughly 450 ANSI lumens), and a high 20,000:1 contrast ratio that ensures sharp text and accurate Rec.709 colors. Key pros include its lamp-free 20,000-hour LED lifespan, a 0.8:1 short-throw lens that projects a 100-inch image from just over a meter away, and PC-free versatility via a built-in media player, microSD slot, and USB port. However, notable cons include its weak 1.5W internal speaker, noticeable fan noise in brighter modes, and a lack of optical zoom or vertical lens shift for flexible placement.
