As home viewing evolves from "being able to see" to "seeing well", a projector that combines image precision with usability has become a core need. On October 11, 2025, Optoma officially announced that the UHZ528 4K Laser Home Theater Projector is about to hit the market. This new product, integrating true 4K resolution, laser light source, and flexible installation design, is redefining the quality standard for mid-range home projectors, allowing users to enjoy a theater-level audio-visual experience without leaving home.
True 4K Image Quality: Every Frame of Detail Stands Up to Magnification
Image quality is the core competitiveness of a home theater, and the Optoma UHZ528 achieves three breakthroughs in visual presentation. It is equipped with a TI 0.47-inch DMD display chip, natively supporting 3840×2160 true 4K resolution and capable of rendering 1073.4 million colors. Whether it is the texture of an actor’s hair in a Blu-ray movie or the geological details in a UHD documentary, all can be accurately reproduced.
For the performance of light and dark levels, this projector fully supports HDR and HLG dual high dynamic range technologies. By optimizing the dynamic range of bright and dark areas, it achieves a viewing effect of "no overexposure in bright areas and clear details in dark areas". When playing the black hole scene in Interstellar, it can not only retain the deep texture of the starry sky but also clearly present the metallic luster of the spaceship. Combined with the stable light output of the laser source, the color transition of the image is smooth and natural, and the color accuracy far exceeds that of LED projectors in the same price range.
Laser Light Source: Stable Output Without Lamp Replacement for 5 Years
The upgrade of light source technology endows the UHZ528 with the advantage of long-term use. It adopts a high-quality Nichia laser light source, which has a service life of up to 30,000 hours in Eco mode. Calculated based on 5 hours of daily viewing, it can operate stably for more than 16 years, completely solving the pain points of traditional bulb projectors such as "frequent lamp replacement and brightness attenuation".
The laser light source brings not only long life but also brightness performance suitable for all scenarios. Even in a living room with unclosed curtains during the day, the image remains clear and transparent; at night, the high contrast feature of the laser source becomes more prominent, creating an immersive cinema atmosphere when matching the dark scenes of movies. This "all-weather high-definition" performance allows users in small apartments to enjoy high-quality viewing experiences without specially creating a dark room.
Flexible Installation: Project a 300-Inch Giant Screen Even in Small Apartments
Targeting the characteristics of Chinese family living spaces, the Optoma UHZ528 has made full efforts in installation adaptability. It is equipped with a 1.3x manual zoom and focus lens, with a throw ratio ranging from 1.21 to 1.59. This means that within a distance of 1 meter to 8 meters, it can flexibly project images from 28 inches to 300 inches—In a 15-square-meter bedroom, a 100-inch giant screen can be projected with a distance of only 2.5 meters, fully meeting daily viewing needs.
For complex placement environments, this projector supports ±30° vertical/horizontal keystone correction and four-corner fine-tuning. Whether it is front-projected on a white wall, ceiling-mounted, or side-projected on the side of a bedroom wardrobe, a square image can be quickly adjusted through the remote control. With a body size of only 274×216×114mm and a net weight of 3.4kg, it can be placed on a TV cabinet or easily stored in a storage box, making mobile use stress-free.
Full-Scenario Adaptation: All-Round Experience from Viewing to Gaming
In addition to audio-visual playback, the UHZ528 also meets diverse entertainment needs. It has built-in 8W high-fidelity speakers and supports virtual surround sound, eliminating the need to connect external speakers for daily drama watching; for those pursuing professional sound effects, an external home theater sound system can be connected through the Audio Out interface to create a stereo sound field.
In terms of interface configuration, two HDMI 2.0 interfaces (both supporting HDCP2.2) can connect game consoles and Blu-ray players at the same time. Combined with MEMC motion compensation technology and low-latency mode, when playing console games such as Horizon Forbidden West, the image is smooth without motion blur, and the operation response latency is less than 20ms. The USB A interface (5V/1.5A) can also provide emergency power supply for devices such as mobile phones, showing thoughtful details in design.
In addition, the projector is equipped with practical functions such as automatic power-on via power/signal source detection and RS232 remote control, enabling convenient operation for both ordinary home users and small home theater scenarios.
Market Positioning: A Professional Choice in the Mid-Range Price Segment
The current home projector market is in a situation where "high-end products have inflated prices and entry-level products have insufficient image quality". The launch of the Optoma UHZ528 just fills the gap in the mid-range market. It integrates three core advantages: true 4K resolution, laser light source, and flexible installation. The expected pricing will target the upgrade range of the brand’s classic model UHD528 (the original UHD528 was priced at 7,999 yuan), but with significant improvements in light source life and installation flexibility.
For home users pursuing a "balance between quality and cost-effectiveness", this new product is undoubtedly the most anticipated home projector choice at the end of 2025. With the official launch of the Optoma UHZ528, the professional home theater experience will further reach more users, allowing more people to enjoy flagship-level audio-visual effects with a mid-range budget.
