Bright short-throw projector with True 4K UHD resolution for classrooms and meeting rooms
The 4K UHD model 4K400x short-throw projector is the ideal solution when you need to project a large image from a shorter distance.
A versatile model designed for future-proof classroom or meeting room applications thanks to its high brightness, short throw and true 4K UHD resolution. The 4K400STx projector provides an excellent image in any environment, even when total control of ambient lighting is not possible.
This projector is equipped with two HDMI ports, audio connectors, USB for 5 V device power, 12 V trigger and RS232 for integration into an existing control solution. The projector's FullHD 1080p resolution at 240 Hz provides a very low input latency of 4.2 ms.
Short throw
Thanks to the short throw lens, you can project an impressive 100 diagonal image from just over a metre away. This allows the projector to be placed closer to the wall, reducing shadows for easier presentations.
True 4K UHD resolution
Ultra HD 4K resolution delivers sharper, realistic images and richer colours, so you can sit closer to the screen and enjoy a more immersive experience.
Our DLP projectors provide CTA (Consumer Technology Association) approved True 4K UHD resolution for 8.3 million pixels on screen. This is four times more detail than Full HD and twice as much as competing technology, which only delivers 4.1 million pixels.
HDR and HLG compatibility
The ability to receive and display HDR10 and Hybrid Log Gamma (HLG) HDR content. This Optoma projector allows you to see significantly more detail and textures. Objects look more solid and realistic and the extra detail creates a greater sense of depth.
Inflammable light projection
This versatile projector combines high brightness and vibrant colours to deliver vivid, realistic images in any environment*. Make a lasting impression with bigger and bolder presentations at any time of day.
*No direct sunlight or light directed at the screen.
Dual HDMI input
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 your games console, set-top box, laptop, computer, Blu-ray player or media streamer with a single cable. You can even turn it into a smart projector by connecting an HDMI dongle such as a Google Chromecast, Amazon Fire TV, Apple TV or Roku stick.
Keystone HV and four corner adjustment
The projector offers horizontal and vertical keystone correction and individual geometry adjustment of each corner of the image to create a perfect square. Perfect for uneven walls or locations where mounting the projector poses problems and must be done at an angle.
Illuminated remote control
Our illuminated remote controls are designed using subtle white LEDs to illuminate the buttons, making them visible and easy to find especially in the dark.
