Optoma’s New Eco-Friendly 4K Short-Throw Projector

Optoma has launched a new eco-friendly projector that is made with 50% PCR (post-consumer recycled) plastics and has packaging that is 97% recyclable. The Optoma UHZ35ST features a DuraCore laser light source that delivers 3,500 lumens. It has a contrast ratio of 500,000:1. When compared to lamp-based models, this projector consumes up to 47% less power and can operate up to 30,000 hours in eco mode without maintenance.

The projector uses a DLP projection engine, capable of producing a 100-diagonal-inch 4K UHD display at a resolution of 3,840 x 2,160. Its short throw ratio of 0.496:1 allows it to project visuals from just a few feet away from the screen, with the potential to display up to 300 inches.

In its Game Mode, the UHZ35ST offers a 240-Hz refresh rate for 1080p content. The input lag measures at 4 ms for 1080p and 16.9 ms for 4K at 60 Hz. Additionally, the projector supports the Rec.709 color gamut and is compatible with HDR and HLG content.

The Optoma UHZ35ST is available for purchase in the United States for an estimated street price of $3,299.
