@ Andrew
Right, but with files coming in from, say, ACR at 16 bit, the banding will be in the display before it occurs in the file (being that the display operates at either 8- or 10-bit)
My point is, wouldn't one be paying extra money for bit depth that doesn't get displayed due to OS X's limitations and therefore be wasting money? Or worse, get banding that isn't there even earlier because the wider gamut monitor requires a higher bit depth to accommodate the "stretched" data.
... or am I worrying for nothing?
Very confused

Hey again,
Since I didn't notice any replies to my last message, I guess I'll try rephrasing my question.
Since OS X does not, to the best of my knowledge, support 30-bits what might be the benefits of using an NEC PA272w or the like if the resultant gamut is restricted to 24 bits? Is it the bump in internal accuracy of the 14 bits per channel LUT that lets it make sense to buy or is there something else I'm not understanding?
Thank you
Dimitri Katsaros

My understanding is - and I stand to be corrected if this is wrong - the bit depth needs to be distinguished from the display gamut. The gamut of these wide-gamut displays is just about ARBG (98), which is what you get whether the bit depth were 24 or 30. The added bit-depth COULD provide for smoother tonal gradations and perhaps more separated shadow detail because it is capable of resolving more distinct levels, computationally. Whether one would be able to see this difference visually I suppose would depend on the file and the acuity of one's vision. Not having had the difference demonstrated to me, I have no idea. All I know is that I have a PA271W connected to my MacPro, calibrated and profiled with BasicColor 4, and I find this set-up provides a very evenly lit, high quality, tonally smooth colour-managed viewing environment from which to make prints that present no surprises as they emerge from my Epson 4900, which by the way has a gamut that in
some parts of the gamut exceeds ARGB(98) on Ilford GFS paper.

One important thing to understand: Gamut isn't restricted by the bit depth.

True... I always knew that... gamut is the extremes of representable colors whereas bit depth is the number of representable colors within said gamut.
My question is, if one is only using a mac and not dual booting, would one not get similar results (assuming the gamut coverage is the same) with an 8-bit per channel display?
Thanks
Dimitri

Maybe yes, maybe no. Depends on the display, the rest of the path, the image and it's bit depth and color space (gamut).
Many of us work with high bit files from the get-go. Why view banding that isn't in the image? IOW, we shouldn't have to ever see banding and wonder, is this in the image data or a result of a less than ideal display path? There certainly IS a point of diminishing return.
