Lol, gimme a break. I can buy 2 Dell Ultrasharps for 1 Cinema Display. That's double the pixel count.
You can laugh out loud all you like, but obviously you miss my point: I am speaking to the High End Graphics Arts Print Production market. Last I checked, some Apple users still worked in this market.
Folks in this industry understand the science behind why an ACD is a better choice over a Dell Ultrasharp, even with calibration on the Dell. I would never put one of my artists in front of a Dell -- even a calibrated one -- Why? Because the Dell has too many monitor adjustments to color, brightness, etc. Laugh at this all you want and call me fool, BUT educate yourself before you do -- if one touches ANY of the Dell's monitor controls after a monitor calibration/colorsync profile, then the Calibrated monitor is basically useless. And this is just the first reason. The more finely tuned LUT's and SWOP certification are numbers two and three. All calibration not-withstanding.
The key in color matching, which is a science, is to let the COLORSYNC ICC PROFILE interact with the Video Card, the Operating System, the Software, and Proof and Offset/Digital Printers (and on initial input a scanner, digital camera, etc).
Again, this is just speaking to the print production market.
For Video the Dell is a better choice.
Want to learn more? Below are a few excerpts from Dr. Karl Lang -- the architect of the Sony Artisan, the Radius PressView, ColorMatch, ProSense and many other products. He worked with display technology both CRT and LCD for the last 15 years.
". . .As an example the fact that Apple's display has no controls other than
backlight is actually a very good thing for an 8-8-8 LCD if your going
to use calibration. Apple optimizes the factory LUTs so as to provide
the most individual colors. smooth greyscale and the least loss. Then
the calibration is done in the graphic card LUT. As these are all 8 bit
it's best if the user does not mess with the display LUTs at all.
Overall Lab to Lab Delta E of 23 patches is a very poor metric to
evaluate a display. It completely leaves out many areas of color space
(the tool they used is designed to make the colorimeter look good so
tuff patches are not included) contrast ratio, stability, aging,
greyscale performance and other important considerations."
Basically, if you understand the science of color management, you would never want 2 Dell Ultrasharps over 1 ACD 30".
And this is just the beginning of the color science tutorial: I have not even begun to really get into it.
Sorry, but in the area of print production, where color match is important, your statement is foolish. In this case you live up to your MacRumors "Newbie" title.
