[QUOTE="bigj, post: 234706, member: 10940"] Well that is my thought. The only (maybe) benefit of letting display do it is that expanding in analog domain or with >8 bit precision may be better. e.g. say a notional display expands to 16bit then it would expand 16-235 by linear interpolation to a range with (smooth) 64K steps. But if you do it source side on the PC in 8bits then you can only expand to 256 steps, and this would then be expanded *again* on display side to 64K. I think this double expansion/quantisation may lead to theoretical artifacts. But if it *is* there it is a) dependent on exactly what the display does, b) probably pretty marginal anyway.
