I've got a Macbook Pro 15" (2017) with a BenQ SW271 connected via USB-C. I've calibrated both using a Spyder 5 Pro, and straight off the bat after calibrating the BenQ felt that it was leaning towards a green cast. Compared with the Macbook's screen, it's certainly much colder looking.
The BenQ screen is calibrated using Palette Master Elements, and I've done so using any tutorial and informative texts I can find. The Macbook is calibrated using Spyder's own software.
The way I see it the problem is two-fold:
1) I do realize that I'll be hard pressed to have the two displays look exactly the same, but the difference here is causing some serious eye strain. Should they not at least look in the same ballpark when calibrated with the same sensor, albeit different software?
2) When I turn off all light in the room, set my DSLR to all manual, focus infinity, wb 5600ish (shot in raw so who cares though) and do center-screen shots of the same bright-white color – one for each display profile – the results puzzle me. The two profiles I've calibrated with the Spyder will yield RGB histograms as follows:
Switching to the pre-calibrated Adobe RGB profile, that shipped with the monitor, yields the following:
Shouldn't the RGB of bright white align? It feels to me like the factory calibration is better than my Spyder calibration results in.
