Problems with 3D
Cannot project correctly in 3D
Check Remedy
Are the 3D Glasses turned on? Turn on the 3D Glasses.
Are the 3D Glasses fully charged? Charge the 3D Glasses.
Is a 3D image being projected? If the projector is projecting a 2D image, or if an error occurs on
the projector that prevents the 3D image from being projected,
you cannot view 3D images even if you are wearing the 3D
Glasses.
Is the input image in 3D? Check that the input image is 3D compatible.
Since most TV broadcasts do not contain a 3D format signal, 3D
reception must be set manually.
