    Bright, True 4K UHD short throw projector for classrooms and meeting spaces

    Discover the short throw version of the 4K400x, for when you want a big screen in a smaller space.

    Future proof your classroom or meeting room with this high brightness True 4K UHD short throw projector. The 4K400STx delivers rich visuals in any environment even when total ambient light control is not possible.

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

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

    Short Throw

    With a short throw lens, you can project an impressive 100” image from just over a meter away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease.

    True 4K UHD resolution

    Ultra HD 4K resolution delivers sharper, life-like images and richer colors - 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.

    True 4K UHD resolution

    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.

    HDR and HLG compatible

    Lights on viewing

    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.


    Use the USB-A port to power an HDMI dongle, such as Google Chromecast.

    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

    Manufacturer’s Pricing Policy

    Why do I need to contact you in order to place my order?

    As an authorized dealer for the product you are looking at, is bound by certain agreements with our manufacturer partners in how we display, price and sell certain products.

    Some items may not be able to be advertised below a certain price or any pricing at all and others may not be able to be added to a shopping cart via an “add to cart” button.

    If a competitor’s website has the same product but is not restricting the display/functionality in the same way that you see here on, than that competitor is likely NOT an authorized dealer.

    What does that mean for you as the customer? It is very likely that the manufacturer may not honor your products warranty, or that your product was never intended for the US market to begin with.
