Features

Living room, classroom, or board room; the 4K400STx 4000-Lumen 4K UHD Short-Throw DLP Projector from Optoma Technology is made to product a bright and lifelike image in stunning 4K resolution. Support for HDR10 and HLG, along with sRGB and CMS support, help to ensure that 4K content showcases rich contrast, texture, and accurate color representation. With 4000 lumens of brightness, it can be used in fully-lit rooms, make it a versatile display option for a home or business. With dual HDMI ports and a powered 5V USB port, the content you display can vary from PC presentations, to movies, gaming, streaming video, and more.

Gaming Ready
For gamers, dropping the resolution down to a Full HD 1080p brings additional benefits. At 1920 x 1080, games still look great, but you also get support for 240 Hz playback with a 4.2 ms response time for a smooth and lag-free performance.
Media Options
Dual HDMI ports are joined by a VGA and 5V USB port to accommodate a host of component options. In addition to a gaming console, you can attach a Blu-ray player or PC. With USB power, you can power optional HDMI dongles and enjoy a smart TV experience from the likes of Amazon Fire TV, Roku, Apple TV, and more.
Perfect Image
Integrated image correction features allow you to dial in a perfectly square image, even when utilizing uneven walls and tabletops. You can use keystone correction to adjust the vertical and horizontal aspects of your projected image, and four-corner correction to warp each corner individually until you achieve a true square or rectangle.
ISF Modes
You only have to make your calibrations once with ISF modes. Create a daytime and a nighttime configuration and save it for repeatable and consistent results.
