In fact, Lightroom can give problems with uncalibrated/profiled monitors, or if the monitor profile isn't correct (as it uses several different colour spaces internally).
I find this statement very interesting and would like to know more. Could you explain this please?
Lightroom uses ProPhoto RGB in Develop Module. (Actually, a variant of ProPhoto with linear gamma for editing, but sRGB gamma for the histogram). So in Develop Module, the image displayed on the monitor is in ProPhoto RGB colour space.
Lightroom previews are stored in Adobe RGB colour space. So in Library Module, it's displaying images in Adobe RGB.
Ideally, there needs to to be a correct monitor profile in place. I think
(but I'm not sure) that Lightroom assumes an sRGB profile if there isn't a monitor profile for the monitor. However, that's very much second-best. To get accurate colours from Lightroom, it's much better to use a monitor that's calibrated/profiled with a hardware device (Spyder, Colormunki, EyeOne, Huey etc).
Also, it appears that Lightroom is more fussy about profiles than some programs. I've read somewhere (but can't find an authoritative link) that if the histogram displayed in Lightroom is brown (rather than grey with coloured peaks) then it's saying the monitor profile is corrupt. In particular, Lightroom won't work with icc v4 profiles. Most more modern profiling/calibration software gives you the choice of v2 or v4 profiles: you need to choose v2 for Lightroom (if you don't get the choice, then it's probably v2).
PS - If there is a correct monitor profile in place, then monitor colour management with Lightroom just works. There are no adjustments or settings in LR you can get wrong. In Photoshop, by contrast, there are lots of ways of screwing up colour settings, which means that if colours in LR don't look the same as PS or another program, then in my experience it's usually LR that's right and the other program that's wrong.
