Hello. I purchased early 2015 13" retina macbook pro end of November, 2016. However, I am experiencing severe image retention problem. Looking at the color profile, I see this info: Manufacturer: 00000610 Model: 0000A02A Manufacture date: CF3C1070 Is the screen LG or samsung? I tried apple solution (screen saver) but it is only a temporary solution. IR is back after about 10 minutes of use. Does anyone have any permanent solution? Thank you in advance.
