All lcd and tft monitors are 16bit colour, so why does videos/dvds look better in 32bit colour?
16-bit and 32-bit shouldnt look any difference if the lcd is only 16-bit colour surely? 16-bit is 16.7 Million Colours right?
15/16 bit is measured in thousands of colours. 24/32 bit is Millions of colours, thats why 32bit looks best and theres no reason to use anything less on todays pcs
Who told you tft's only display 16 bit? You've been BS'd mate.
Just for the record
16 bit = 65,536 colours
32 bit = 4,294,967,296
Well, at least that's how it should be.
Quite an informative (if a little dry) article:
Read "the colour depth issue", about 1/3 way down. Should clear everything up!
its 24bit + 8bit, the 8-bit being the available greys hence 32-bit.
technicaly speeking its 16.7 million collours, the rest is greys.
A 10-bit implementation isnt viable at the consumer level, it would achieve 30-bit colour plus another 10-bits for the greys.
Look at the lcd specs at overclockers, They all say 16.2 million colours. I would of thought 32bit is 32 million colours?
To work out the number of colours available for a given bit-per-pixel count, raise 2 to the power of bitdepth.
16bits = 2^16: 65,536 colours
24bits = 2^24: 16,777,216 colours (16.7 million)
32bits = 24bits with 8bits of alpha channel information (256 levels).
the 16.2M I dont understand, I think its because the panels are using 6-bit LCD which dither to 16.2M colours. I dont know about you but anything less than 8-bit will have banding no matter how good the panel is.
to help with all the terminology on TFT's:
24bit = 8 bit = 16.7 million colours
18bit with dithering = 6 bit = 16.2 million colours
18bit = 6 bit = 262,144 colours
