Also, can the xx89S support and display all the colors in 48-bit Deep Color sources(when there are some)? You said LED DLP's have a higher color gamut so I was wondering if it's as high as 48-bit Deep Color.
I also sent you a PM. Thanks John!
I think explaining this as bit depth will help out. There are three primary colors (green, blue, red) when one hears 8 bit processing what we are really discussing is 8 x 3 primary color = 24 bit color depth, and 10 bit processing x 3 primary color = 30 bit color depth. 12 bit processing x 3 primary colors = 36 bit color depth. 16 bit processing x 3 primary colors = 48 bit color depth.
See how this is beginning to relate to HDMI 1.3 spec which supports 30-bit, 36-bit and 48-bit (RGB or YCbCr) color depths, up from the 24-bit depths in previous versions of the HDMI specification.
8 bit processing = 1.67 million colors (256 gradation)
10 bit processing = 1.07 billion colors (1024 gradation)
12 bit processing = 68.7 billion colors (4096 gradation)
16 bit processing = 281.4 trillion colors (65536 gradation)
Now if you were looking at a B&W image that only had 256 shades of grey you wouldn't have a great image (banding) but as you increase the number of gradation to 1024 you achieve much less banding. Now add the primary colors each to this scheme and you end up with 1024 x 1024 x 1024 = 1.07 billion shades of gray.
What consumers need to know is that the standard single DLP processor supports 1024 shades of gradation, and some expensive multi-chip DLP projectors support 4096 shades of gradation.
