Hey everyone.
I'm new here, - just found this thread and read through all of the posts and thought I'd sign up and join. I just returned a 13" nMBP the other day and got a new one in exchange. Unfortunately I wasn't aware they had different panels and so I didn't check that before making the exchange. The one I returned was purchased alongside another one at the same time (my girlfriend's which hasn't been exchanged) and the comparison between those two were the reason why I exchanged mine. Now our nMBP's look the same. Here's a pic of the differences between the one I used to have and the one she still has. We now both have the A034 panel. Like I said, I didn't check what panel the one I exchanged had but do you think that one might have had the A033 panel? I've never owned an Apple product before but I figured that the difference you can see on the photo really wasn't supposed to be there, which is why I exchanged it without hesitation. It definitely looks like a defect that the one on the left is so reddish when viewed from almost all angles. Sitting in front of them, there was little difference. I should note that the ones we have now also look quite different from the ones they had in the store. They looked blue-ish/brighter and ours look a little dimmer and yellowish. The one I returned looked very different from all of them - much too reddish. I kinda which the ones we have now (A034) looked more blue-ish/brighter like the ones they had in the store rather than dim/yellowish. In the store I checked the calibration settings and they were default so they didn't look different because of a change of settings. I didn't check what panel they had though as I only just now figured out how to do that by reading this thread. Considering that the two A034's we have right now look completely similar (I would take a photo, but my girlfriend is not home and has hers with her), I suppose we should be satisfied with them although we'd both prefer more brightness? They look very uniform and not yellowish anywhere such as the ones that have been displayed in this thread. When I say they look yellowish in comparison to those in the store, it's really only because those in the store looked really blue-ish and very bright. Ours definitely looked pretty dim compared to those. All comparisons are of course based on the same brightness level (max) and the same factory default white point calibration.
Finally, is there any software that allows you to measure the nits on your screen? Wondering if ours would have a slightly smaller nit-level than expected (as they look a little dim compared to those others I've seen in the store).
Thanks guys, good thread you've got going here.
