Are there any 3D displays available today? What about 3D content?
A number of displays on the market are already 3D capable, including many DLP models. Likewise, there are already some content sources, such as gaming consoles that are 3D-capable. The 3D support introduced in HDMI 1.4 fills an important role by providing an input/output connection that can handle 3D content, and this could help launch consumer 3D video into the mainstream.
