The Epson EMP-715 and EMP-505 are versatile projectors that exemplify the best of Epson's innovation in the field of visual display technology. Designed for both business and educational environments, these models combine high performance with user-friendly features.

At the heart of the EMP-715 and EMP-505 is Epson’s proprietary 3LCD technology, which ensures superior color reproduction and brightness.

With a brightness of up to 3500 lumens, both models excel in delivering clear presentations in rooms with varied ambient light.

This resolution is ideal for detailed graphics, presentations, and video content, allowing users to display text and images with impressive sharpness. Additionally, they support various resolutions for maximum versatility, adapting to different content and formats seamlessly.

These features enhance the projectors' versatility, making them suitable for various presentation scenarios.

The EMP-715 and EMP-505 also include advanced features such as keystone correction, which allows users to easily adjust and correct image distortion when projecting from an angle. This makes it easier to achieve a perfect image from any position in a room.
