    4K UHD Projection from Optoma
    See incredible detail, contrast and color for a cinematic experience from the comfort of your home with Optoma 4K Ultra HD projectors. 4K UHD (3840 x 2160) resolution delivers razor-sharp images with an impressive 8.3 million pixels for exceptional detail and smooth video.

    High dynamic range delivers superior contrast while wide color gamut transforms on-screen objects with vividly realistic colors. These technologies combine to enable a 4K UHD experience, intensified with an Optoma projector.

    Four times the resolution of 1080p. There’s 8.3 million pixels of resolution – four times higher than 1080p – for breathtaking realism that lets you feel like you’re in the movie, experiencing every wave crashing on the beach, the feel of a car behind the driver’s seat or explosions on the huge screen

    Recreate the cinematic experience. With a TV, you need to sit 5-6 feet away for the optimum picture quality – most sit further away. With Optoma 4K projectors, sit as far as 10 feet away to see all 4K pixels, for a truly immersive experience.

    HDR-Compatible. Optoma 4K projectors feature HDR technology and HDR10-compatibility for darker black-levels, brilliant whites and greater color depth, for an elevated home viewing experience.

    Aligned, razor sharp images so you can enjoy the show. Optoma 4K projectors use a single DLP chip system. DLP 1-chip projectors are inherently alignment-free for perfect convergence and easy set up.

    • DLP Technology
      DLP (Digital Light Processing) is a proprietary technology from Texas Instruments that offers digital projection with higher contrast, faster response time, good pixel structure and virtually no color degradation.

    • Full 3D
      Display true 3D content from almost any 3D source, including 3D Blu-ray Disc™ players, 3D broadcasting, and the latest-generation game consoles. Support for 144Hz rapid-refresh rate provides ultra-smooth flicker-free images. Optoma 3D glasses required.

    • Dynamic Black Technology
      This feature gives more depth to your image by smoothly adjusting the lamp output to create a stunning high contrast ratio. Bright scenes appear crisp and clear, while dark scenes remain detailed with deep blacks and exceptional light and shade detail.

    • PureMotion
      Using sophisticated frame-interpolation technology, advanced motion control processing eliminates motion blurring or image judder, even in high-speed action sequences. PureMotion works in both 2D and 3D and is optimized for 1080p24.

    • UltraDetail
      This technology ensures all the information contained in an image is accurately reproduced on the screen to give a stunning crystal clear, pin-sharp picture. Complex algorithms detect each frame and improve image sharpness before the frame is projected.

    • PureColor
      This mode allows the projector to reproduce more detailed shades of color for vibrant, natural-looking images. Colors are more saturated and more accurate.

      Vertical Lens Shift
      Vertical lens shift simplifies installations by shifting the image up and down without image distortion to provide a wider range of projector placement possibilities, making it easier to position the projector in a room.

    • HDR
      High dynamic range (HDR) technology delivers brighter whites and deeper black levels. Optoma HDR accepts HDR10 signals with four selectable picture modes: Normal, Bright, Detail, Film

    • DCI-P3
      Color the way it is meant to be seen – rich, colorful and cinematic pictures and games via DCI-P3 wide color gamut coverage.

    • BT.2020
