Optoma 4K400STX 4,000Lumens True 4K UHD Short Throw Projector

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.

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.

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.

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.
