Karl Lang makes a number of interesting points here. Thank's for echoing his
post on this List -- I'm not a member of the Yahoo Epson Wide Format Forum.

So it seems that a lot of Karl's rant against current LCD technology hinges
around the fact that we don't have 10 bit video cards to hook into those
RollsRoyce that are the high-end Eizos and NECs?
We have 16 bits in RAM and "virual" color space but he's got a point when he
writes that current 8-bit video pipelines can't do justice to the subtlety
of 16 bits RGB. Or even 8 bit AdobeRGB or eciRGB.
But I am always sadden to think that, a few years ago, there was a company
called SGI that came out with a 23" LCD driven by a 10bit board -- even had
its own optimized sensor -- and no one went for it! What ever happened to
those $2500 Radius Thunder24 board: didn't these also had 10 bit video
circuitry? I mean what's holding a company like Apple, who's supposed to
lead the digital graphics market (and if we are to believe what Roger
Simonov said in his talk in Phoenix last december this is the year of
virtual proofing) to come up with 10 bit video on the Mac? Are they too busy

I wonder where? Karl did not say.

Interesting. All these LCDs are still dependent on 8 bit video architecture
on the host or am I missing Karl's points? Sorry to be so dense at times.

So leave the display in its native white point I guess is the best
recommendation of the ACD. I wonder what Remote Director and Kodak Virtual

That I agree. It's better than no patches at all but we definitely need more
patches and some kind of uniform sampling scheme to do an adequate job.
Monitor profiling packages have been slow to respond, if at all, in my
opinion, to help with this very assessment: why? (Some packages are really
still in the dark, It's not funny...)

Looks like NEC has the lead in the affordable good quality LCD department.
It always had for me. I personally never cared for the Viewsonic or the
LaCIE. But I must confess I once fell of my chair on a Dell 21" Trinitron --
man, the controls on this CRT were just awesome.
