Future proof your classroom or meeting room with this high brightness True 4K short throw projector. The 4K400STx’s bright image delivers rich visuals in any environment even when total ambient light control is not possible.
This Optoma short throw 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 240 Hz with 4.2 ms input lag when connected to a PC, making it an ideal choice for a short throw gaming projector.
Short Throw lens: lets you project an impressive 100″ image from just over 3 feet (a meter) away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease.
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.
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 best 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 setup, 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. It’s ideal for uneven walls or where projector placement is awkward and requires installation at an angle.
Backlit remote: designed using subtle white LEDs to light up the buttons, making it easy to see and operate, especially in the dark.
