Using this movie, I have made adjustments to the color settings in order to minimize the yellow. Three questions: 1) Has anyone else noticed this? 2) Does this show up on the other Optoma projectors as the default color setting as well? 3) Are there other users who have minimized or eliminated this via calibration? I freely admit that I didn't calibrate the color settings but simply eyeballed the picture to adjust them to my liking. Now, there's a huge difference when I alternate between the 3D and the User settings, with the User settings resulting in a display that looks black-and-white to me. As I said, I would have expected more discussion about this...
I've only run across one comment about the yellowish cast that I mentioned in the post above, and it was on a different thread. I'm still surprised to hear so little on this subject.
Here are the settings that work best for me. I use RF glasses (Optoma ZF2100), so I can't vouch for those with different glasses. I am also simply assuming that the default settings on recent Optomas are the same or very similar.
Go to the 3D (default) mode and change the following color settings:
Red no change
Green no change
Blue from 0, 0, 0 to 0, 0, 25
White from 0, 0, 0 to -16, -16, 25
Cyan no change
Magenta no change
Yellow no change
(All other 3D settings no change)
The 3D default settings are automatically saved to the User settings. (Be sure the projector is displaying a 3D signal before making the above changes, otherwise they are associated with 2D mode.) This should get rid of the yellowish tint.
If you now alternate the projector mode between 3D and User on a black-and-white 3D movie such as CREATURE FROM THE BLACK LAGOON, you'll see a big difference. If you switch back and forth while watching a color 3D Blu-ray, the changes may not be noticeable in all scenes, but in black-and-white 3D the difference is very obvious. The default 3D mode settings will have a much stronger yellow tint than the User mode settings.
