Optoma Ships 'World's First' Alexa-Compatible HT Projector with 3D

Optoma has announced the availability of a new 4K UHD projector with Alexa compatibility, the UHD51A. The projector is the world's first voice-enabled home theater beamer to integrate with Amazon Alexa via the new SmartProjection for Smart Home skill, enabling projection to align with speakers, screen, lighting and more in any smart home setting. First unveiled at CES 2018, the Optoma UHD51A was announced as the Best Home Theater Product in the International CES 2018 "Best of CES Awards" presented by Engadget, according to the company. Many forum readers will also be pleased that the PJ also includes Full 3D (with the support of a 144Hz rapid-refresh rate), and Optoma 3D glasses are available as an accessory.​

Optoma is enabling home theater enthusiasts to integrate large-screen video into their Alexa smart homes, tying in with speakers, lighting and other devices. An estimated 8.2 million people have an Amazon Alexa device, and there are now more than one billion voice searches per month, according to Alpine.AI. Exclusive to the Optoma UHD51A, the SmartProjection for Smart Home skill will allow users to power the projector on and off, change volume and input source, and control the USB 4K UHD Media Player.


The award-winning Optoma UHD51A integrates the latest technology enhancements in color and 4K resolution for 'market-leading' performance, says Optoma. The new projector includes a light output of 2,400 lumens, 500,000:1 contrast ratio, and HDR10 with Rec.2020 / DCI-P3 Wide Color Gamut support, and Blu-ray 3D compatibility. The unit also features a built-in 4K UHD HDR media player and Android OS, along with a pair of HDMI 2.0 inputs with HDCP 2.2 support to ensure compatibility with the latest 4K UHD devices and consoles with HDR at 60 Hz refresh rates for image smoothing.


"Optoma's leadership in the consumer home theater space has largely been attributable to our ability to design and deliver projectors that leverage the latest innovations and technologies to deliver a great entertainment experience at an affordable price point," said Brian Soto, head of product management at Optoma Technology. "With smart home adoption on the rise, and voice increasingly becoming a preferred way for consumers to interface with their electronics, we prioritized delivering this feature to our audience."

In keeping with the company's history of compelling pocket-friendly price points, the Optoma UHD51A is available from Amazon, Fry's Electronics (in-store), Best Buy, Beach Camera and B&H Photo for an estimated street price of $1,699.
