LE26M51B 3.2bn Colours or 6.4bn Colours?

I want to get this TV, most sites claim it's got 6.4bn colours, although the Samsung website says 3.2bn....

Can anyone confirm what it really is?

Thanks

I can't give you a definitive answer but 3.22Billion (US Billion) is 10-bit, and 6.44Billion is 11-Bit colours.

This is how I think the numbers are calulated, its using binary 2^10 colours per subpixel (3 subpixels RGB per resolution pixel), and then they count each pixel.

Note that 8-bit is calulated differently and dosen't take account of the number of pixels, 16.7million = 256 * 256 * 256.

i.e

8-bit = 2^8 * 2^8 * 2^8 = 16,777,216 (256 colour levels per subpixel)
10-bit = 2^10*3*768*1366 = 3,222,798,336 (512 colours levels per subpixel)
11-bit = 2^11*3*768*1366 = 6,445,596,672 (1024 colour levels per subpixel)
12-bit = 2^11*3*768*1366 = 12,891,193,344 (2048 colour levels per subpixel)

btw if you connect via DVI (or DVI to HDMI cable) you only get 8-bit, and at the moment there are not many 10/12-bit HDMI sources (I think HD-DVD has 12-bit potential).

I would be glad if someone can correct my mathematical assumptions, as I'm struggling to get a definitive answer on the web.
