      I picked up the two Canon WUX5000 projectors we'll be using for our coming Convention yesterday, and they came with a ColorMunki calibration gizmo. So being an honest sort of a bloke, I emailed the owner and asked if I could try it whilst I had hold of it, and he said yes, that was OK.  I've only used it for my two monitors, and I can't say that I am in anyway impressed with the results. 

       

      Of course it might be user error, but I did break the habit of a lifetime, and RTFM'd.  Plus I dl'd the most up to date version of the software.  The resulting profiles are noticeably dimmer than my un-calibrated screens, but that is OK because they are very bright as they came.  But what is most definitely not up to scratch is if I create a big white document in Photoshop, Tab of all the panels so I can make said document straddle both screens — which butt up against each other — that large expanse of supposedly pure white, is night and day different on the two screens.

       

      My main Dell 2709W has a faint green tint, while my second LG24EB23 is looking much closer to white in my eyes, but might have just a trace of pink.

       

      It’s midnight here, so the calibration was done under room light (low energy neon thingies) so I’ll be interested to see how they look in the morning.  Meanwhile, if Dag, or anyone can give me some pointers, I’d be very grateful.  I had everything tuned off in Preferences, as suggested in the instructions I read.

          Ah, well, matching the white point of two displays of different technologies (LED or CCFL), different brands and different models is always tricky and not always worth the trouble. But if you want to go ahead and try, you will almost certainly need different target settings.

           

          Getting the white point right (luminance and temperature) is the one major consideration that everything else hinges on. You need to trust your eyes. What you want is a good visual match to paper white - given your specific working environment. So when you say "dimmer" the question is what your targets are. The general recommendation of 120 cd/m² may not work for you (my own is 110 at work and 95-100 at home).

           

          Once you have the white point nailed (and possibly the black point too, if you want to be really critical), all the rest falls into place by itself.

           

          As for temperature, the software usually lets you adjust along the blue/yellow Kelvin scale. However, if you need to adjust along the green/magenta axis, that often means you have to dive into the monitor's OSD "advanced" section. This is one of the advantages of hardware calibration to the monitor's internal circuitry, as opposed to software calibration in the video card (that's what the Munki does).

           

          The ColorMunki sensor should be top notch. It's generally the same sensor as the i1 Display Pro (which I'm using with NEC Spectraview II software). It is generally regarded as one of the very best and most consistent colorimeters on the market.
