Dim Retina LCD assemblies


Lately we've been seeing Retina replacement LCD's (full assembly) that are noticeably dimmer then the original OEM.
Anyone have any idea what is exactly is causing this issue, is there such thing as an inferior backlight they are using? could it be knockoff LP154WT1 inside? Is it possible its some kind of EDID issue not allowing 100% brightness?
Sick of sending these things back, wasting everyones time.
Any information on what exactly is going on with dim screens is appreciated!


Noticed it too. I suspect it;s the LCDs as the rest is usually OEM parts. Pretty much all A1398 are now like this, A1502 can still be found that are good.
