I just got my rMBP back from the repair depot, and unfortunately it has an LG display. I can see some retention when using an image retention test like this, but I'm not sure if it will sufficiently pass the genius bar test to get the display replaced since I've heard it's a fairly apple-biased test. Can anyone who's had it done describe what they do to test it? How long on the checkerboard etc, and did yours pass or fail? Thanks.
Got a tip for us?

Genius Bar image retention test

And play RUssian roulette with Apple and hope that after the fifth return I get a good screen.
If under general use you have ghosting, then I agree it needs replacing. But you're doing some idiotic 8min test designed to make it happen. Come on dude!
Mostly because people probably don't notice it under normal operating conditions. Forcing the issue such as that test doesn't really mean the display has a problem.
Nonetheless if you're not happy with it, then return it for repair. Just because its an LG display means it's bad.
I have image retention when I do that test, but I have absolutely no image retention 100% of the time during other uses. There's no reason for me to return it if I can't find a flaw with it without seriously looking for it.
I bet I could find pits in the aluminum if I wanted to take a powerful microscope to it, but I won't do that because I don't care since I can't see it anyway.

I was seeing image retention but it did not fail the Apple test when I took it in and they wouldn't replace the screen. However a few months later I lot several stuck pixels in a line and they replaced the screen with a Samsung, no more image retention.
I had IR on a 2015 15" A02E panel and it showed IR after just 3 minutes when running the test. I was actually surprised to see this on a 2015 model however the real reason for my return was the white point was just too warm for my liking. I made an appointment with the Genius Bar, they ran a field test then did not even bother to test the IR and just gave me a replacement.
They plug into their local network and then boot from their own server, this puts the MBP into a special diagnostic test mode.
