with ddcctl you can also adjust rgb gains.
----- Settings (testing) ----- -rg <1-..> [red gain] -gg <1-..> [green gain] -bg <1-..> [blue gain] -rrgb [reset color]
At least with my Dell P2715Q it worked:
❯ ddcctl -d 1 -rg 1 D: NSScreen #722475023 (2560x1440 0°) HiDPI I: found 1 external display I: polling display 1's EDID I: got edid.serial: V7WP95C1837L I: got edid.name: DELL P2715Q D: action: rg: 1 D: setting VCP control #22 => 1
Can we read the current rgb shift values of the internal display?
Is this needed? When I enabled night-shift it automatically gets applied to all my monitors. I've never noticed it not syncing properly.
Oh, you're right. Just tried it out manually via the system prefs
