This was exactly what I was after when I asked the question if the eeColor supports 10/12 bit deep color. This is completely different than 12-bit 4:2:2 (which has been a standard since HDMI 1.1). The Radiance cannot output 10-bit 4:4:4, which is considered a "Deep Color"' mode. It can only output 8-bit 4:4:4. When you set the Radiance to output 4:4:4, the dithering settings are meaningless and are not used at all (unless you dither all the way down to 6 or 7-bits).
I have come to the conclusion that 4:4:4 is the better output mode (even though it's only 8-bit). I believe that the 8-bit per-pixel chrominance accuracy on 4:4:4 is better than the extended 12-bit color depth on 4:2:2 (because 4:2:2 loses chrominance resolution due to shared chrominance for 2 consequtive pixels).
The exception here is if your projector converts everything to 4:2:2 anyways for its internal processing pipeline (which I have heard the JVCs may do). If this is the case, then it's better to output 4:2:2 so that you can take advantage of the 12-bit color depth. For my Sony VW95ES, it's better to send it 4:4:4 because there is motion blur that occurs with 4:2:2 (due to fluctuating chominance values for an object that moves across the screen). This is fixed if you use 4:4:4.
As far as sending Deep Color to the eeColor, there's no point in doing this if you have a Radiance in the mix, since Radiance does not support Deep Color anyways. You could try running your bluray (set to 10-bit deep color) directly to the eeColor, but your going on the assumption that the deinterlacer/scaler in the bluray player is going to be as good as or better than the Radiance at processing the 4:2:0 that's on the disc. This depends entirely on what bluray player you have (and what video processing chip it contains).Edited by Aaron Inami - 3/30/13 at 11:14am
