DLP-Link projector issue

Dear Sir,

When you say “Projectors do not use checker board 3D content”, do you mean that (a) the source material is not checkerboard 3D or (b) the projector doesn’t support checkerboard 3D?  To let you know, checkerboard 3D is a 3D format commonly used by manufacturers of 3D-capable DLP™ televisions, but it is not a format commonly supported by 3D-capable DLP™ projectors.  The support is determined by the projector manufacturers.

When you say “problem is lack of 3D content sync”, do you mean that (a) the source material isn’t being recognized as 3D or (b) the 3D glasses are not syncing?  Again, if your 3D source material is in the checkerboard 3D format, a projector may not recognize it as a valid 3D source and/or may not be processing the data correctly since the projector may not support checkerboard 3D.

All DLP link projectors do not sync to 3D content.

The DLP-Link shtter glasses only sync to frames but not to frame content so there is always random 50% chance that glasses are in sync with content.

Users are very flustrated having to press menu button hudreds of times to corect the eye order manually.

All DLP-Link projector do not use checker board signal to sync the eyes with content.

The DLP-Link system is incomplete and manufacturers blame Texas Instrument stating that it is a problem with TI's firmware and TI needs to correct the problem.

Here is an example from OPTOMA:

Hello Mathew,



You are correct that the sync needs to be corrected if the content changes (either starting, stopping, or paused). There is no fix for this other than making the correct menu option when this happens.



Best regards,

Joshua Allen

Problems:The DLP-Link has no sync with 3D content and one must manually set the correct eye order every time movie starts, movie is paused or if there is a glitch. What is the problem and how can I correct it. Please advice. Sincerely, Mathew Orman

Please advice how to fix the problem.

DLP™ projectors are based on a different technology platform than DLP™ televisions, so they have different sets of capabilities.  Checkerboard 3D format is commonly supported by manufacturers of DLP™ televisions, but it is not commonly supported by manufacturers of DLP™ projectors.  It is up to the manufacturer – not TI – to implement support of various 3D formats.

DLPLink™ is a standard established by TI, but it is up to the manufacturers to implement it.  DLPLink™ cannot identify whether or not a frame of source data is Left or Right; it depends on the system correctly identifying & labeling Left/Right frame data based on the source input.

Thank you.

It is clear now that manufacturers have not fully implemented DLP-Link standard.
