In the process of getting a new computer, I had the choice of getting the new retina macbook pro. After searching the web, I found out that there are some ghosting and image burn problems with some of the displays on rMBPs out there. In the end, it turns out that there are 2 manufacturers who actually make the screens: LG and Samsung. The LG screens show problems, whereas the Samsung ones don’t (at least not yet).
Well, how do you find out which manufacturer made your screen? This seems to be a question that is bothering a lot of people out there. Simply going to system properties won’t do you much good – you won’t find anything there. I found a workaround which will help you in this case. Solution – open your terminal and type:
ioreg -lw0 | grep IODisplayEDID | sed “/[^<]*</s///” | xxd -p -r | strings -6
Read the output. If the prefix to the output on your screen is “LP”, well then, I am sorry – you are looking at an LG screen.
