I am not trying to be argumentative, I would just like to get the best out of the system. I had a Lumagen before and that is how I thought it worked. You calibrated for one source using the projectors controls and then used the Lumagen's controls for any variances in the other sources. I assumed this would be the same principle just using the Oppo's controls.
The difference in this case is that the OPPO is KNOWN to put out correct gray scale on HDMI 1 using explicit 1080p output and its default settings. The discovery that you have to alter the OPPO's Brightness and Contrast settings means that something peculiar is up. And it's worth trying to figure out what.
Evidently something odd is going on with the other players you've tried. It could be that the players themselves are putting out odd gray scale -- which would be something of a coincidence from more than one player -- or that you are using a different video data format from those players compared to what you are using from the OPPO, and the rest of your video chain (AVR and Display) are reacting differently to the two video formats.
For example, if you were using RGB from the other players and YCbCr from the OPPO, that could indicate that your AVR or Display have a quirk in the way they handle RGB input. Or if you are using Deep Color from the OPPO but not from the other players. Or if you are using 1080p/24 from the OPPO but not from the other players. These video format differences SHOULDN'T make a difference but they are likely candidates to check since there IS a difference.
It could also be that the input you are using for HDMI video from the OPPO has some setting difference compared to the inputs you are using for the other players. Presumably you copied over settings to configure the new input. Perhaps one didn't get copied correctly? Check in particularly for any sort of video "enhancement" settings in the AVR or Display such as dynamic contrast adjustment.
Now understand, the setup as you are using it now probably looks fine, and may indeed end up being the best you can do -- given what the other players are putting out, and their lack of Picture Adjustment controls.
But the discovery that you need to change the Brightness and Contrast controls in the OPPO to get a good match with a calibrated display should be a Red Flag that something is wrong in the calibration setup.
