Three new Optoma 4K UHD projectors are making their debut at CES 2018—well, two distinct models, one of which will be available in two varieties. All are based on Texas Instrument's 4K UHD DLP single-chip imaging technology.

The biggest news is the UHD51A , which integrates with Amazon Alexa Smart Home and Custom Skills. The basic specs include 2400 lumens of peak light output, 500,000:1 dynamic contrast ratio, support for HDR10 high dynamic range and wide color gamut, and an RGBRGB color wheel. It also includes a built-in 4K UHD media player and Android OS along with two HDMI 2.0 inputs with HDCP 2.2. It is expected to be available in the spring for an estimated street price of $1699. The UHD50 is identical, except it does not include Alexa voice control, it has a white casing instead of black, and it will sell for $1499.

Also of interest among the new Optoma 4K UHD projectors is the 4K UHD HDR Laser UST. Can that really be the official model designation? Seems like quite a mouthful! Still, the name says it all—4K UHGD resolution, support for HDR (presumably HDR10), laser light engine (presumably laser-phosphor), and UST (ultra-short throw). That last part means it can be placed very near to a wall, creating a 100-inch image from a mere 8 inches away with a 0.25 throw ratio. Other specs include a peak light output of 2300 lumens and a 2,000,000:1 dynamic contrast ratio. This model is expected to become available in the second quarter of 2018 with a target price of $4999.

According to Brian Soto, head of product management at Optoma Technology, "Optoma is continually focused on introducing more innovations to the home theater space, with everything from resolution and light sources, to form factor, features, and mobility—and now voice integration—to simplify the experience for consumers and deliver an inch-for-inch entertainment experience that TVs simply can't match. With smart-home adoption on the rise, consumers are looking at non-traditional technology options that bring them a better entertainment experience, and Optoma home-theater projection delivers this in spades."
