  • 4200 Lumens 4K UHD Projection

    The ZK420UST is one of Optoma's most compact and hassle-free 4K DuraCore laser projectors to date. Designed for 30,000 hours of maintenance-free operation, this 4200-lumen projector delivers powerful and eye catching image performance, perfect for meeting rooms, classrooms to immersive installations.

    To support Optoma’s commitment to sustainability, the ZK420UST designed with the environment in mind, the eco-friendly chassis design is made with up to 50% PCR (Post-Consumer Recycled) plastics and the packaging contains up to 97% recyclable materials.

    The ZK420UST features an ultra short throw lens meaning it can project a 100” image from less than 12 inches away, avoiding shadows being cast across the screen from the presenter(s). For ultimate convenience it comes with RS232, HDBaseT3.0 & OMS (Optoma Management Suite) for monitoring and controlling.

    Features
    Bright 4K UHD laser projector - 4,200 lumens

    Ultra short throw lens - 100" image from less than 12 inches away

    OMS Cloud - Centralized management, broadcasting and reporting

    Control flexibility of HDBaseT 3.0 - 4K, HDR and HLG compatibility

    Ultra Short Throw
    With an ultra-short throw lens, you can project an impressive image greater than 100” from less than a metre away from the projection surface. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease; perfect for interactive applications.

    True 4K UHD resolution
    Ultra HD 4K resolution delivers sharper, life-like images and richer colours - allowing you to sit closer to the screen and enjoy a more immersive experience.

    Our DLP projectors provide CTA (Consumer Technology Association) approved True 4K UHD resolution, capable of projecting 8.3 million on screen pixels. That's four times more detail than Full HD and twice as many from competing technology, which only delivers 4.1 million pixels.


    HDR and HLG compatible

    Capable of receiving and displaying both HDR10 and Hybrid Log Gamma (HLG) HDR content. This Optoma projector allows you to see far more detail and texture. Objects look more solid and lifelike and the extra detail creates a greater sense of depth.


    Four corner correction

    Four corner correction enables the keystone of the projector to be adjusted in both the vertical and horizontal plane, so you can individually warp each corner of the projected image to make it perfectly square. Ideal for uneven walls or in spaces where the projector placement is awkward or limited and needs to be installed at an angle.

    Lights on viewing
    This versatile projector combines high brightness and vivid colours for vibrant, true-to-life visuals in any environment*. Make a lasting impression with bigger and bolder presentations any time of day.

    *With no direct sunlight or lights directed on screen.


    Laser technology
    Optoma laser projectors use high-quality lasers to create the projected image. In many situations the perceived brightness from laser illumination projectors can be twice that of an equivalent lamp-based model. They also deliver increased efficiency to maintain consistent brightness, superior colour performance, instant on/off and an extraordinary life span of up to 30,000 hours.

    360 projection*
    With 360° projection,* images can be displayed in any orientation, giving you the freedom and versatility to install this projector in the desired location.

    *For more information please refer to the user manual
