Color God restore Optoma 4K cost-effective projector evaluation
In recent years, 4K technology has become standard in the TV industry, but 4K home projectors are still relatively rare. However, Optoma has made a strong entry into the market with three 4K home projectors, and among them, the UHD660 stands out as a flagship model. Known for its superior color performance and 4K resolution, this projector is designed to deliver an immersive viewing experience. Today, we're excited to take a closer look at this impressive device.
**Color Performance & Key Features**
As the top-tier model in Optoma’s 4K lineup, the UHD660 features a DLP 4K UHD image processing chip paired with BrilliantColor technology, allowing it to produce vibrant, accurate images. It offers 2300 lumens of brightness and an impressive contrast ratio of 1,200,000:1, along with 10-bit color depth for smooth gradients and rich color reproduction. The lamp life is up to 4,000 hours under normal use, and with power-saving mode, it can be extended to around 10,000 hours. The built-in dual 4W speakers provide decent audio output, and the projector supports manual focus, vertical keystone correction, and screen position adjustment for flexible setup.
