Bright Mode & Ambient Light: Space and Installation

The Optoma UHD55 is equipped with a metal halide bulb that emits a powerful 3,600 lumens of brightness, enough to maintain high picture quality in virtually any indoor space. Its bright mode makes it an excellent choice for indoor/outdoor use as well, enabling you to enjoy backyard movies even before complete darkness sets in.

Optoma UHD55: An Ideal Standard-Throw Projector

The UHD55 is a standard-throw projector, requiring about 10 feet of distance between the lens and screen for a 100-inch image, making it best suited for larger spaces. However, it compensates for this with its flexible installation options. It comes with a vertical lens shift (+5%/-15%), a 1.3x manual zoom, and a 4-corner keystone correction (+/- 40°) for easy wall color adjustment.

Wireless Connectivity and Automation Capabilities

The Optoma UHD55 shines in terms of connectivity. Its rear panel includes dual HDMI, VGA, and USB inputs, and an optical audio out for connecting external speakers. The built-in wireless connectivity (we included UHD55 among top wireless projectors), supports voice control through Alexa or Google Assistant, as well as custom automation routines through IFTTT. The rear panel also houses ports for other smart home setups, like a 12-volt trigger, and RJ-45 and RS232 connections.
