Verdict

The Optoma HZ48UST is a Full HD 1080p ultra short throw laser projector that delivers a bright 4,500 ANSI lumens output and an impressive 3,000,000:1 dynamic contrast ratio, capable of projecting a 100-inch image from just 30cm away. Its core strengths include a long-lasting 30,000-hour DuraCore laser light source, Rec.709 colour accuracy for cinematic visuals, and low input lag for gaming, all housed in a 24/7-operation certified chassis with four-corner keystone correction. However, notable drawbacks include its lack of 4K resolution, the absence of smart TV features or built-in Wi-Fi, and a relatively high operating noise level of up to 35dB.
