    4000 Lumens, 16:9 4K UHD HDR


    Bright, True 4K UHD projector for classrooms and meeting spaces
    Futureproof your classroom or office space with this high-brightness True 4K UHD projector.

    The 4K400x projects the finest of details in any environment even when total ambient light control is not possible.

    This projector boasts dual HDMI ports, audio connections, USB to power 5V devices, 12V trigger and an RS232 to integrate into your existing control solution.

    In addition, when needed, enjoy 1080p in 240Hz with 4.2ms input lag when connected to a PC.

    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.

    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.

    Dual HDMI inputs
    Play games, stream videos and share photos on the big screen in the comfort of your own home.
    With dual HDMI inputs, you can easily connect to your games console, set-top box, laptop, PC, Blu-ray player or media streamer with a single cable. You can even turn it into a smart projector by connecting an HDMI dongle like the Google Chromecast™, Amazon Fire TV, Apple TV™ or Roku® stick.


    Amazing colour

    Optoma projectors provide reliable colour performance suitable for any content and environment. From accurate sRGB colours for lifelike images to vibrant punchy presentations. We have a display mode to specific meet your needs. Perfect for a range of graphic and video presentations.


    Colour Management System (CMS)
    Display accurate lifelike colours to best match your viewing environment. This unique feature provides you with the flexibility to fine-tune the colour settings of your projector for optimal precision.

    ISF modes
    This feature allows you to save your calibrated day and night mode settings for the highest possible viewing experience.


    Integrated speaker
    Complete your home entertainment experience with the convenience of a powerful built-in speaker for exceptional sound quality and an easy set up without the need for costly external speakers.

    USB-Power
    Use the USB-A port to power external devices (5V/1.5A)

    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.

    Backlit remote
    Our backlit remotes are designed using subtle white LEDs to light up the buttons, making it to see and operate, especially in the dark
