I'm going to ask a question here which is probably stupid and has probably been answered a million times before, but anyway...
I'm trying, and totally failing, to colour match two monitors attached to a Mac Pro trashcan. One is an Eizo CS270, about 2 years old, the other is a Quato 240LE, about 8 years old. I'm using an i1 Display Pro, ColorNavigator on the Eizo, i1Profiler on the Quato. i1Profiler cannot access the Quato's hardware control so I have to set RGB & Brightness manually. I'm calibrating to 6500K, 100cd, using L* on the Eizo and default Gamma on the Quato.
Both calibrate without error and give good results. But the calibrated displays, showing Apple's Solid Gray Dark, are completely different. If I look at either on their own, they seem ok. But together, the Eizo is much more contrasty. On the Quato there seems to be a green-ish tinge, but the grey is anyway more like what I expect a Mid-Gray to look like. The problem is I have no idea which is correct. I suppose in both cases the monitors think they are displaying neutral grey, but clearly either one or both is not.
My expectation is that calibration should being me into the ballpark. I don'r expect an exact match, but neither do I expect a glaring difference. Up until a few years ago I also used an ageing 1st generation Apple Cinema Display, and even that I could get close enough to the Quato to not bother me.
Are my expectations excessive ? Any suggestions on how I can troubleshoot ?
Thanks!
