Optoma has introduced its cheapest 4K projector yet, the £1500 (AUD$2740) UHD51. Designed as a low cost UHD home theatre display, the single chip DLP model uses Texas Instruments XPR technology, and is the first in Optoma’s 4K range that supports Full 3D. With 3D support now absent on all new 4K TVs, the move by Optoma to embrace 3D Blu-ray and broadcasting could be a canny one. The UHD51 is also HDR compatible.

Connections include two HDMIs, one of which is 4K HDCP 2.2 capable, and a USB power port, to stream content directly from an HDMI dongle. There’s also a modest onboard sound system.

The colour gamut covers 100 per cent of Rec.709 (in Reference mode) and has Optoma Amazing Colour image processing, with an enhanced colour wheel and image presets. Other niceties include PureMotion frame-interpolation processing, to reduce image judder and motion blur on movies and sports.

Installation options are limited to basic vertical lens shift; the projector has a 1.3x zoom with a 1.21-1.59:1 throw ratio.There’s a 12v trigger for integrated screen and AV system control. Light output is rated at 2,400 lumens. Operating noise is said to be 25dB.
