It is good to know that proprietary software like Zen does not change the images too much. You had me worried for a minute. At the same time you are really selling those HP monitors.
This raises an interesting point about preparing images with the later viewer in mind. The HP ZR30W sounds fantastic but most people do not have one. At best readers see pics as an onscreen .pdf, otherwise projected in a darkish room or mangled by an inexpensive color printer. It makes some sense to check image products on a non-awesome monitor to make sure the key point still comes across. For projectors we note which ones have decent contrast, and for the vast majority we need to boost brightness and contrast until it looks a little nuts on the computer screen before it projects well.
Of course this also argues strongly for non-arbitrary quantitative image measurements. Even a cheap color printer cannot ruin those.
All the best,
