Roger, as you may be aware, that other guy may not; the bit depth of the panel
is simply one attribute to a fully high bit display path. Yes, it's important.
But the video card, the OS, the application and the panel all have to be high
bit for a true high bit path.
Photoshop and Lightroom support high bit video, later Mac OSs do as well (late
to the party but there's support).
Then there's the video card that may or may not be high bit. If not, there's
going to be a high bit to 8-bit conversion which isn't ideal.
How one hooks up the display affects this too.
Best way to check, view this image, in Photoshop, at 100% zoom, should be
utterly smooth:

As for a silly comment: "Eat that NEC", there's far, far more to a great color
reference smart display system than the bit depth. We can go there if so
desired.
All bits are real. Not all comments about them are <g>.
