Thank you for your interest in DLP(r) Link.
You are correct that DLP 3D Ready projectors do not support the DLP HDTV
checkerboard input as the display devices used in our projectors and our
HDTVs are made differently. The DLP 3D Ready projectors do, however,
support 120 Hz or 60 Hz inputs as well as 120 Hz output frequencies.
The native format for the DLP 3D Ready projectors is frame sequential 3D
(as opposed to checkerboard, side-by-side, or over/under). The benefit
of using this format is that there is no compression of the image as in
the other 3D formats, but the drawback is that the projector must know
how to decode which frame is used for the left eye and which frame is
used for the right eye. There are many proprietary encoding and decoding
formats that will allow the frame sequential source material to insert
metadata into the content to mark each frame and have the display device
decode it correctly, but unfortunately, there is no mainstream standard
of how to do this with current 3D content. Current DLP 3D Ready
projectors, therefore, do not automatically support this type of
automatic left/right detection. Most, if not all, DLP 3D Ready
projectors have a menu control to invert the L/R sequence if a pseudo
stereoscopic condition exists. The same control also exists on most 3D
software and 3D compatible PC graphics cards.
In recent months, this 3D standard situation has changed with the
adoption of the HDMI v1.4a standard. This standard defines 7 different
3D formats that all display devices must support. Since it is a digital
interface, the content is in a fixed format and it is very easy for the
display device to know which frame is used for left eye and which is
used for right eye. Our more recent home theater 1080p DLP projectors
that support HDMI v1.4a (including BluRay) formats do not have the
problem of pseudo stereoscopic image display. As more and more of the
DLP 3D Ready projectors adopt support for the HDMI v1.4a standard, the
pseudo stereoscopic issue will no longer be an issue.
