Description

The Optoma ML750i is an ultra-portable LED projector weighing 425g and small enough to hold in one hand. It is built for moving between home, office and client sites rather than for fixed installation.

Resolution is WXGA 1280x800 with 700 lumens (450 ANSI) and a 20,000:1 contrast ratio. The fixed 1.5:1 lens covers screen sizes from 30 to 80 inches at throw distances of 0.55m to 3.23m.

The projector can run without a laptop. Built-in memory, a media player and an office viewer let it play content straight from a USB drive or microSD card, and it supports mirroring and casting from phones and tablets. Auto keystone and auto focus square and sharpen the image on setup.

The LED light source is rated for 20,000 hours. Noise output is low at 29dB to 32dB, and a built-in speaker covers audio.

Note the 450 ANSI lumen figure is the meaningful one when comparing against conventional projectors, so this is best suited to controlled lighting.
