Optoma has announced availability of the UHZ55 laser projector, a follow-up for its UHZ50, a 2021 model that was then ground-breaking among home entertainment projectors for its laser engine and gamer-friendly low input lag.

Like its predecessor, the UHZ55 is a 4K single-chip DLP model using TI's 0.47-inch chipset with 4-phase XPR pixel-shifting. The laser light source is rated the same at 3,000 ANSI lumens, in this case from the company's DuraCore engine spec'd for up to 30,000 hours in Eco mode. It also carries along the earlier projector's Enhanced Gaming Mode offering 16.9 millisecond input lag for 4K/60 Hz signals and compatibility with 1080p/240 Hz signals from gaming PCs with response time as low as 4 ms.
The UHZ55 is a standard-throw projector with a 1.3X manual zoom offering a 1.21:1 to 1.59:1 throw ratio, with a commensurate projection distance of approximately 47 inches to 26.6 feet; the 16:9 image size is spec'd at approximately 34 to 302 inches diagonal. Adding setup flexibility are up to +10% vertical lens shift, and ±30% vertical and horizontal keystone correction as well as 4-corner correction and warping.

Designed for home theater/entertainment viewing as well as gaming, the UHZ55 is a smart projector with integrated dual-band WiFi that uses the Optoma Marketplace streaming platform with apps that include Amazon Prime and supports wireless mirroring from PCs and personal devices via the company's Creative Cast app. It also offers compatibility with Alexa and Google Assistant voice commands, as well as Google Home compliance for control via the Google Home app. The projector touts HDR10 playback with the option of employing a DCI-P3 WCG (wide color gamut) mode, as well as HLG. Furthermore, the UHZ55 is compatible with 1080p 3D content, a feature that we see less frequently today in new consumer projectors but which Optoma continues to support.

The projector offers a generous connection panel with three HDMI 2.0 ports. A pair of built-in 10-watt speakers are available for audio, though one of the HDMI ports is equipped with eARC for sending signals of up to Dolby Atmos quality back to an audio system or soundbar. Three USB-A ports are available, one for powering dongles or other devices and two compatible with a built in media player for content delivered via thumb drive. Optical digital audio and 3.5 mm stereo analog audio outputs are provided, and control ports include a 12V trigger output, an RJ-45 LAN connection, and RS232C. There is also a 3D Sync connection for an outboard emitter.
The Optoma UHZ55 is available now from popular online retailers for $2,499.

Add all that to Optoma's poor reputation currently and even with the extra $500, the 4550i seems like the easy choice.
