On PC's, the key issue is to be aware of how many LUTs (Look Up

This is what we do here, and it works very well. this issue is another powerful argument in favour of buying one really big, great monitor rather than, say, two smaller ones!)ДЄll that being said - once you have done this, you can normally achieve a thoroughly workable result - just remember to do all your colour work on the primary screen. Marvel, and curse, at the amazing human eye.

It's simply an unfortunate fact of life that this is a problem that is not truly solvable. Once you've done the best you can.that's it! There really isn't more you can do. In all cases, you're manipulating the calibration target arbitrarily simply to increase the visual match.

Is the the secondary screen higher or lower in contrast? If yes, experiment with different black points or even gammas.

Is your secondary screen warmer or cooler than the reference screen? If yes, re-calibrate the secondary screen to a different whitepoint to compensate (the numerical figure you use is essentially irrelevant, you just want a better visual match).

With the PDI or similar displayed, check for overall issues: After this initial calibration is completed, we visually assess the match with the Eizo monitor - the best way to do this is to use a continuous tone test image (like the famous PDI printer test image) - rather than just looking at your desktop or large blocks of single colours - as the goal is to improve the match with overall colour reproduction, not just the reproduction of specific tones (unless, of course, you have a particular family of tones of critical importance to you - in which case use an image with those tones of course!). Initially, we calibrate the BenQ to the same settings, except we lower the brightness to 80 cd/m2 to help our eyes white balance of the primary screen.

So we designate the Eizo screen as the primary reference monitor and calibrate that to our usual fine art printing target (90 cd/m2, 5800 K white, 0.4 black, gamma 2.2, full native gamut). The BenQ is amazing for its price, but it's just not up to the level of an Eizo CG screen. So, for example, on our primary services station here we currently (Jan 2019) have two monitors in use - an Eizo CG2730 and a B enQ SW240. What this means, in practise, is manipulating the calibration target of the secondary screen in any way you can to increase the visual match. And typically, we recommend doing this, but to a slightly lower brightness level - just to make sure your eyes' response is biased towards the primary screen. Then, calibrate any other screens 'to' that reference screen for the best visual match. So - the best practise is to designate one screen - your best screen - as your primary reference monitor for colour work. In practise, though, I've never seen this work even vaguely well.

In theory, this should mean the secondary screen knows more about the primary, and adapts itself to it. Some monitor calibration software has a feature that allows you to load up a profile made for one monitor into the other. So - given that, what can we do to mitigate the problem - i.e. The human eye is just too good at picking even the slightest differences. The fact is that this is a problem you can't really solve.

In some cases, the video system does not support calibration at all! (This is fairly rare in 2019 though).

To make things truly match would take a prohibitive amount of time - the system would have to measure and correct each of thousands if not millions of tones to achieve a perfect visual match.

To make things truly match would require prohibitively expensive machines - calibrators that can detect these marginal differences, and screens that offer such fractional levels of adjustment that these issues could be fixed simply cost too much to make.

in LED backlighting - and this means that unit to unit variance is higher than you might think, even with very high quality screens Even the most minute difference in white will seen by even an untrained human eye.

In particular, the way white balance and chromatic adaptation work with the human eye - means that we extraordinarily sensitive to differences in white tones (i.e.

your desktop background, or a white screen) - your eye will pick even slight difference in those tones.

The human eye is so sensitive that when you see large blocks of a single tone (e.g.

Here are some of the reasons it doesn't work the way we naturally expect: Like most things in life, solving this problem is far more complex than it initially looks. There's are many reasons why multiple monitor calibration does not achieve a visual match between screens.
