2018 MBP screen issues (now had 5 machines, all had screen issues in one way or another):
#1 - 3 x horizontal shadowy lines across the screen - one near the bottom, one in the middle, and the last near the top.
#2 - Pink on the left, blue on the right
#3 - Flaw in the glass panel - resulting in pressure on the screen, top right and causing a 2" vertical pinch point/shadow running down the screen from the top menu bar 3/4's of the way along the screen. Very little horizontal shadowy lines on this one however and no tint - frustrating as this would otherwise have been a perfect machine (I was concerned the glass flaw would result in a cracked screen at some point)
#4 - 3 x horizontal shadowy lines across the screen again - confirmed by multiple Apple guys in the store.
#5 - Opened in the store, pink on the left, blue on right. 1 x Apple guy saw it, 3 others didn't.
I also used a couple of 15" MBPs in the store and they had the horizontal shadowy lines to some degree (and one had the pinch point shadow too to a lesser degree).
FWIW every panel was LG.
Have now given up on playing the screen lottery and got a full refund - will likely revisit at some point in the future once I've got fed up of Windows 10...
Where your shadow issues worse than the screenshot I posted? or similar?
I cannot return for refund, so trying to justify returning it 5 times for repair... which is 5 weeks prolly.
