Optoma has announced a new lamp-based gaming and home entertainment projector, the UHD55.
With a street price of $1,799 out of the gate ($2,599 in Canada), the UHD55 uses the 0.47-inch DLP chipset that achieves 4K (3840x2160) onscreen resolution with four-way XPR pixel shifting technology. The projector's lamp is rated for 3,600 ANSI lumens and has a life expectancy of 10,000 hours in Standard light mode (4,000 in Bright mode, and up to 15,000 in Dynamic Black mode). Optoma lists a contrast ratio of 1,200,000:1. The UHD55 has vertical lens shift, a 1.3x optical zoom with a throw ratio of 1.21-1.59:1, and support for vertical keystone correction and 3 x 3 warping.
For HDR, the projector supports HDR10 and HLG signals, and wide color gamut support at 97% DCI-P3 coverage with a shutter enabled. 3D is also supported in side-by-side, top and bottom, and frame sequential formats. Smart home compatibility for Amazon Alexa, Google Home, and IFTTT is also built in.
While the UHD55 supports a refresh rate up to 240Hz (from a computer), 4K is limited to 60Hz due to Optoma's including only HDMI 2.0 (with HDCP 2.2) for both inputs. (The introduction of HDMI 2.1 ports on most DLP projectors has lagged due to limitations of the most common chipsets.) Still, the input lag on the UHD55 is impressive at 16ms with a 4K/60Hz signal and down to 4ms with 1080p/240 signals.
