Please see my December 11 entry for details on yet another problem cable and still no solution, but the good news is that NEC is sending me a cable that they think will solve the issue. If so, I’ll certainly be trumpeting that fact here ASAP.
Meanwhile, Apple evades the issue with a lame tech note that sidesteps the question of a solution.
Apple seems to think that no one buys anything but their obnoxious mirror-finish screens, and the tech note ignores the fact that it’s the 2010 Mac Pro that provoked this headache. The GT120 in the 2009 Mac Pro didn’t have this problem; Apple introduced it with the 2010 Mac Pro. As if the advice to “visit www.vesa.org” somehow is a solution. Take responsibility Apple, and come up with a solution for your customers who are dropping $4K - $10K into a Mac Pro system.
