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.

About the Optoma 4K400STx 4K UHD Short Throw Projector
The Optoma 4K400STx is a 4K UHD DLP projector built for short-throw setups: a 0.5:1 throw ratio puts a very large image on the wall from close range, so it works in smaller rooms and above a media console. It pairs a 4,000-lumen lamp with HDR-ready 4K input, four-corner keystone correction and a built-in speaker, which keeps setup simple. Against long-throw 4K projectors it trades placement flexibility for closeness, and against LED and laser rivals it gives up long light-source life and needs more manual adjustment. It suits movie and sports rooms, gaming at high refresh rates and bright living rooms where a TV would be too small.

Pros
- Short 0.5:1 throw fills a large screen from a few feet away
- Native 4K UHD resolution with HDR input
- 4,000 lumens holds up in rooms with some ambient light
- Four-corner keystone plus horizontal and vertical correction eases off-axis placement
