Apple Care fixed my laptop and they put a new LCD in it, because the old one had blotchy areas. As I want to sell the laptop (got new MBP from work a few weeks ago) I wonder if the new one is LED backlight or not. It's definitely super bright, but since the old one was 2.5 years old and they fade, I can't tell if it's like the original one was when I bought it, or better. Is there a clear way to find out, apart from the rather subjective test of seeing if it's at full brightness instantly? The "Parts used" list just specifies that 646-0314 DSPL, 15.4", WXGA++, AG, CHIMEI, M1 There's no further useful information under "About this Mac: Graphics/Displays" Thanks for any suggestions.
