Optoma projectors can display true 3D content from almost any 3D source, including 3D Blu-ray players, 3D broadcasting and the latest generation games consoles. Full HD (1920 x 1080) has more than twice the resolution of HD Ready (1280 x 720). EH515 is compatible with HDTV broadcasts and high-definition media to project impressive full 1080p images and video in their original digital brilliance. The built-in speaker offers excellent audio support. Easy to set up without the need for costly external speakers. Using the specially designed lamp modes, you can reduce the power consumption by up to 70%. Each mode also has a positive effect on the lamp life, while lowering the total cost of ownership and reducing maintenance. There may be instances when the projector is left running when not in use. To help save energy if the projector is left running and no source is detected, the 'Auto power off' feature automatically turns off the projector after a set period of time. Stay in control of your presentation with Eco AV mute. Direct your audience's attention away from the screen by blanking the image when no longer needed. This also reduces the power consumption by up to 70%, further prolonging the life of your lamp. Simplify installation with PureShift, which provides a wide range of projector placement possibilities.
