I have a Mid 2014 Macbook Pro 15'. When I plug into the iMac as in a display mode : the whites are brighter, while the macbook seems more yellow/saturated. When I plug into a Monoprice that uses an LG panel used in iMacs: same story as above. I bought a Dell P2715Q 4k display, and when I plug into it, Dell looks pretty yellow/saturated. I tried to calibrate all monitors. I can't get the first step like the directions say (gray oval in between two shades of gray). So not sure if that affects my calibration attempts. I took the MBP to Apple store, and it is very comparable with the other MBPs in the store. The color profile that I use is default that it came with. Macbook Pro + Monoprice Macbook Pro + Dell Questions: Is there a better way to calibrate these? Could it be something with my ports/software? Does anyone experience this as well? Thanks!
