I don't know if this thread is still on-topic, but since I just got my MBP...
I haven't noticed any specific grain so far. In fact, the (glossy) screen looks pretty much perfect. Touching wood here...
For what it's worth, the display is a 96420 (if I read the "PCS Illuminant" string correctly).
Hi,
Could you go to systems preferences, click on display, then click on the color tab, choose colorLCD on the left, then click on 'open profile' on the right. In the new window that pops up, scroll down to #13 and tell us what it says underneath under 'manufacturer' and 'model'
Thanks!
