About Optoma 4K400STx

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.

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 colors for vibrant, true-to-life visuals in any environment. Make a lasting impression with bigger and bolder presentations any time of day.

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

Color Management System (CMS)
Display accurate lifelike colors to best match your viewing environment. This unique feature provides you with the flexibility to fine-tune the color settings 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 an HDMI dongle, such as Google Chromecast.

Four corner correction
Adjust the keystone in both the vertical and horizontal plane. You can individually warp each corner of the image to create a perfectly square image. Ideal for uneven walls or where projector placement is awkward 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.
