I guess to keep the viewing angle consistent, I'll turn down the reggae :) Point taken, thank you for the explanation. If I sit here at work (Samsung 2443BW, a 24" TN) with my head in the centre of the screen, the grey rectangles (about Zone III-IV) at top of the screen are a whole stop darker than those at the bottom of the screen.

You'll see the relative brightness of all the grey rectangles changing in a most disturbing manner. For a demonstration, set LFPF to the orange/grey skin ("Blackend" in the little dropbox bottom-left of this thread) and bob your head up and down by about a foot. It matters a lot less for B&W, but shadow detail is highly variable with respect to viewing angle. So when you look at the image, it might be "right" but you move your head and it's not anymore, which means you can't confidently set your white/black points, let alone colour balance, uniquely and know that what you've done to the file is even remotely like what you thought you did to the file. The reasons are that they have poor gamut (display a smaller colour space than any files you might want to work on) and the brightness and hue varies with viewing angle. Images look great on the screen, and print predictably as well. I've defied your dire warning, and have been a happy, pro-TN-panel user for three years, with no adverse effects suffered yet :)
