Ultra-short-throw 4K UHD projection for conference rooms, meeting rooms and professional spaces
TheOptoma ZK420UST is one of Optoma's most compact and easy-to-use 4K DuraCore laser projectors to date. Designed for 30,000 hours of maintenance-free operation, this 4,200 lumen projector delivers a powerful and captivating image, ideal for meeting rooms, classrooms and immersive installations.The ZK420UST is equipped with an ultra-short-throw lens, enabling it to project a 100-inch image from less than 0.6 m away, avoiding shadows cast on the screen by the presenter(s). For optimum convenience, it is equipped with RS232, HDBaseT3.0 and OMS (Optoma Management Suite) technologies for monitoring and control.
Laser, DuraCore and ultra-short-throw technologies
This Optoma ZK420UST laser projector uses a high quality laser to create an image. In most situations, the perceived brightness of this laser projector can be twice that of a traditional lamp-based model. It also offers greater efficiency in maintaining constant brightness, superior colourimetry, instant on/off and an extraordinary lifespan of 30,000 hours.
The impressive lifespan is achieved using Optoma's new DuraCore technology, advanced laser diode cooling techniques and an innovative dust-resistant design.
The Optoma ZK420UST has an ultra-short focal length. With an ultra-short throw lens, you can project an impressive image of over 100 inches to within 0.614m of the projection surface. This allows you to position the projector closer to the wall, reducing shadows so you can present with ease; perfect for interactive applications.
HDR and HLG compatible
The ZK420UST is capable of receiving and displaying HDR10 and Hybrid Log Gamma (HLG) content. This Optoma projector allows you to see much more detail and texture. Objects appear more solid and realistic, and the extra detail creates a greater sense of depth.
4-Angle Geometric Correction
The ZK420UST gives you access to an excellent 4-angle geometric correction that allows the projector to be trapezoidal both vertically and horizontally. This means you can individually adjust each angle of the image to create a perfectly rectangular picture. An ideal feature for distorted walls or when projector placement is difficult and it needs to be installed at an angle.
