I bought my wife a new 15" rMBP for her birthday! We brought home the new machine and set it up. The picture was absolutely amazing. Checked and it was a Samsung screen. We then loaded the latest OS update, started the update process and got a gray screen during the restart. It froze with a plain gray screen before shutting down to install the update. I manually powered down and the install process finished. All was good. Went to bed and woke up and the darn thing would not power on. My wife took it back to the authorized Apple reseller (not Apple Store) and they simply gave her a new machine after the in store tech tried to power on the first machine with no luck. We set up the replacement (new in box) last evening and I immediately noticed the difference in the screen depth of color and general pop to the images. The screen is not as glossy as the Samsung. More of a matte look. I checked and sure enough it is an LG. Is there anything that we can do? Or are we stuck with the LG screen? I do understand that Apple needs to be able to competatively source their components, but it would seem that quality control would have rejected something as significant as a screen if it did not look the same. I am disappointed to say the least. Any suggestions? Thanks!
