I just got a MBP from the refurb. It has a 9C84 panel. Upon turning it on for the first time, I thought the grey startup screen seemed a bit magenta. Neither hot (yellow) nor cold (blue), but magenta.
The default profile is way too washed out (no wonder, it's gamma 1.8).
I tried to calibrate it with the colorsync assistant but every step of the advanced procedure had the rightmost "tint slider" off-screen, impossible to grab ! Never seen that before. Also, once I clicked into that rightmost box to move the slider, I could never get the tint to look right (it was working on my iMac), the values I can choose don't have enough range (which explains why the slider is out of the window by default).
The end profile is too blue, even though the gamma value I dialed in (2.2) is closer to reality and colors look less washed out. So I have to use only the basic calibration options, I set the gamma to 2.2 instead of 1.8 and things look less bad.
What I find very annoying on this screen (maybe it's just the 9C84) is the greys going magenta when my eyes are a bit higher than full frontal position.
Try this : put a Finder window in the center of the screen. Make it inactive (click on something else, like the desktop). Now the window elements are all grey. Tilt the screen towards you (or move your head higher) until the alternating blue/white lines blend together.
Now look at the -normally grey- window elements, the toolbar, the shortcut pane on the left : they are slightly magenta now.
How does it look on everyone's screen ? it would be good to know. This is a big issue for me, much more than overall yellow-ness or blue-ness of the screen, or even black level (which seems quite good on my machine, even though when I look at it from above, I get the same washed out image as in this other thread, leftmost computer, the same background image is set on my computer for accurate comparison purposes)
