Dead pixels seem to appear over time on MBPR
I have my MBPR now for a couple of months. Checked the screen for dead pixels when I bought the screen. Last week I started to see one dead pixel. Now a couple more had appeared. Can this be a progressing problem? In other words can a screen "grow" dead pixels over time and when does Apple repair the screen?
Thanks for the answers
