I need to replace the cracked screen / display on my 2021 MacBook Pro 16" model A2485.

After researching and price checking all my options, and getting tons of quotes / estimates, I’ve decided I’d like to just buy a display module and install it myself.

However, I’m not clear on what features will be disabled if I do that… and I could not get a straight answer from the Apple “Genius” I talked to.

It’s my understanding that the TrueTone feature will not work if I go the DIY route. I’m OK with that, if it will save me a couple hundred bucks. But I’ve read conflicting info re: the fingerprint reader and the display’s “angle sensor” (?) One person told those features need to “calibrated” to “work properly” and that only someone with an “Apple GSX Account” can make those calibrations.

But does that mean those features won’t work at all if I DIY it?

I know about Apple’s Self-repair program, where I can buy the display from them for $700, install it myself, have them “certify” the repair to get TrueTone working again, and also get a $90 trade-in value on the cracked display, so, apx $620 total repair. But I’ve also found the same part for $500.

Can anyone give me a definitive answer on what feature(s) would not work any more if I replaced the display myself, using a “genuine Apple” part I bought off eBay?
