My first MBP was one with a 9C85 display. For unrelated issues, I got a replacement, which happened to have the 9C84 panel. I calibrated both screens to the same, and brightness levels were also set to the same (3 notches down from max). In person, there was a huge difference. The 9C85 had a yellowish tint that I didn't realize existed until I had the 9C84 right next to it. The white is much whiter on the 9C84. BUUUUUT, I would have been happy with the 9C85 because it already appeared to be so vivid in colour.
I snapped a photo of both side-by-side... sorry for my smudge marks on the one on the right... they were just around the left edge as I grab on to the side to adjust the angle every so often.
so which one is which on that pic? and i cant tell a big difference from that pic.
It doesn't make any sense to talk about "teint" unless both screen are set to native Gamma and Color-Temperature!
OS X comes with an activated color-profile that surely isn't optimized for the different screens. So what looks good on one may look "yellowish" on the other. But that's not the screen then, but the profile. You can set the profile to native settings by using the "Calibration" button in the monitor settings.
And even then your impression will be purely based on what color temperature your room light has. Furthermore even if you turn your room into complete black darkness you cannot tell which of the two screens your eyes will adapt to (like the more brighter one).
The only way to tell the difference is to use a hardware calibration device (Eye One 2, Spyder, whatever).
I checked my 84 at native Gamma and Color-Temperature and found out that the first 7 gradations are missing completely (actually gray 7 does exist, but it's the same as grey 8), which means they are plain black regardless of viewing angles. Additionally the vertical viewing angles are so narrow that the breaking point between being able to see dark gradations and having black wash out to gray is very close together.However, as a poster mentioned above, using the standard Leopard aurora background as a test showed that the 84 has more black-level steps/clarity. Looking in the bottom right as the other user instructed revealed a diffusion pixelation on the 85 that was vary apparent. The 84 on the other hand handled the transition much more smoothly. The diffusion is barely detectable.
To the same what? To the same profile?My first MBP was one with a 9C85 display. For unrelated issues, I got a replacement, which happened to have the 9C84 panel. I calibrated both screens to the same[...]
I take it the 9C84 is a TN? If I look from the bottom the colour inverts just like any old cheap TN. My old MBP had a much better screen. Speakers are **** on this one too.
Surely with a calibration device or profile, both screens will looks the same ?
Not necessarily, I'm afraid. I have a 9C84 and a 9C85, each independently calibrated, and of these two units the 84 is obviously the superior screen. Not saying that's necessarily the case with all of them, but definitely with these two. Used by itself, the 85 is a great screen and looks gorgeous---until you set it next to the 84, at which point the 85 looks yellowish and noticeably less bright.

I snapped a photo of both side-by-side (9C84 on left, 9C85 on right)... sorry for my smudge marks on the one on the right... they were just around the left edge as I grab on to the side to adjust the angle every so often.
Is the 9c84 really the better display?
