Image Retention Question

I'm also concerned about this as well. I purchased a rMBP of week 30 (July) and also suffer from [very] faint image retention. However, upon researching image persistence/retention further, I've reached the possible conclusion that this faint IR/IP we're experiencing is temporary and is something that happens to new displays. I may be wrong, but that's all the information I've gathered thus far. I still have 11 days left on my 14 day no-questions-asked return period, so if it worsens, I'll let you guys know.

 

No, what you are experiencing is a characteristic of all display panels. When you turn down the brightness off, all it does it turn off the LEDs. The crystals are still turning on and off in the background and displaying the image.

In fact, in the older CCFL-backlit panels where the inverter (which provides the voltage for the CCFL tubes) burnt out, one could diagnose the problem quickly by shining a flashlight through the Apple logo and seeing if there was an image.
