This is a discussion on 3D not recognized by TV within the DirecTV forums, part of the Cable and Satellite Providers category.
Also, check and see that the DirecTV Genie is setup for 3D too in the settings.

What type of 3d format supports your television, because there is many formats of 3D And perhaps your television doesn't supports all formats of 3D also check the HDMI cable perhaps are using an cable which doesn't support 3D formats
