High-definition Images with 4K Enhancement Technology
4K enhancement technology shifts each pixel diagonally by 0.5 pixels to double the resolution to 3840 x 2160, surpassing full HD image quality to give you unbelievable sharpness, clarity and detail on all your presentations.

Epson 4K PRO-UHD
Delivers an amazing 4K UHD experience with advanced pixel-shifting, resolution-enhancement technology*4.

Flexible Installation with Optical Lens Shift
The wide lens shift range of these projectors provides exceptional installation flexibility. A short focal length as little as 300cm is possible with a 100-inch screen. A broad shift range of 96% vertically and 47% horizontally with the optical lens shift function also keeps image deterioration low, allowing you to position your projector at any point in the room.

Compact Design for Easy Ventilation
Designed with the air intake and exhaust at the front so that you can easily install them even in narrow spaces. Place them on a bookshelf or close to walls without worrying about maintaining clearance for ventilation.

Active 3D with Bluetooth Glasses
Lighter than InfraRed 3D glasses, the Full HD RF 3D Glasses™ are more comfortable and can be connected smoothly via Bluetooth without any transmission interference from obstacles in the room.

High Contrast Ratio
Epson Auto Iris Technology adjusts its aperture to provide optimum contrast and brightness for each scene. You’ll be able to project beautiful well-defined images whenever you are, regardless of ambient light.

Wide-range Connectivity
With integrated support for multiple connection methods, including HDMI to suit a wide range of entertainment devices, these projectors make home entertainment more accessible than ever.

Enhanced HDR Function
Enjoy more vibrant, brighter and sharper images with the enhanced High Dynamic Range (HDR) function. With the wider HDR10 parameter range and 18Gbps support, users can adjust the brightness and gradation of projected images with greater detail and accuracy to project even 4K/60p HDR content such as Netflix.
