Auto Display Mode for Blu-ray 3D

Optoma provides “3D” display mode to resolve the issues related to variations in brightness of 3D images due to overlapping signals and use of specialized lenses. When a 3D signal is received from Blu-ray 3D, the system directly switches to [3D] mode to elevate image brightness and contrast.
