Hi All, Hoping someone can help me with this conundrum. We use Apple M1 laptops connected to Eizo CG monitors for colour accurate work. The monitor is calibrated using the internal monitor sensor and the correct profile is showing in display settings. The monitor is mirroring the laptop. Now, when the Laptop lid is opened or closed, the monitor's display shifts warmer or cooler, with no change in display profile. Is this normal behaviour? I can't fathom why, or work out how to stop the shift... and it begs the question, which is the correct colour? Thanks!
