LG and Samsung are the only screen manufacturers for the Apple Retina MacBook Pro line. It is an interesting fact to know but why would someone want to find out their screen manufacturer when it works fine?. Well, that’s where the problem comes in.
Recent discussions on Apple Support Communities have shown that some Retina MacBook Pro laptops are facing screen burn-in issues. Screen burn-ins usually occur on older TVs like Plasmas, where a static image appears on the screen forever. This is usually permanent but the case with modern day LCDs is different. The issue with the Retina MacBook Pro is of something called ghosting or image persistance. The latter is a more appropriate term. Image persistance is temporary but annoying.
But don’t worry, not all Retina MacBook Pros have an image persistance issues, and the ones that do have happen to be manufactured by LG. So how can you find out your screen manufacturer? It’s quite easy.
Step 1: Open Terminal. You can do this by pressing ⌘ + Space Bar. Type in Terminal in the Spotlight.
Step 2: Paste in the following command into your terminal and press enter.
ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6
Step 3: Note down the message. Luckily, I have a SAMSUNG screen. Yay!
Color LCD LSN154YL01001 DLM303600J5F49HB3
How did I find that out? It’s simple.
LSN = Samsung
LP = LG
Step 4: Go, rejoice if you got a Samsung screen. Get sad if you have LG, because you will face image persistance at some point.
