You guys are trying to turn a specification into a problem.

There are NOT 4 revisions of this panel floating around within 3 weeks, sorry. I'm a manufacturing engineer, so might actually know what I'm talking about. You can't just grab a new version of something off the shelf and toss it in without significant process and product validation activities and a ton of statistical data analysis and all the gate reviews that go with it. And the supplier sure hasn't done a DOE (Design of Experiment) multiple times to create 3 additional panels, validate them, test them, build them, ship them, and have Apple put them in a product and blindly send it out the door. It just doesn't work that way guys, sorry.

One tiny, insignificant change to a production line is a tremendous and arduous activity, and this would not be a tiny, insignificant change.

I have an A1 produced two months after other A2 panels, so there goes that whole revision theory.

Whoa, you have an A1 panel? I’m sorry, but you have ghosting and smearing. Don’t you know that Apple secretly revised all the panels and starting making A3 and A4 panels that fix this issue?

Wait until the A10 panel hits shelves next December. The refresh rate is so fast it causes temporary blindness if stared at too long.

I'm very confused about the issue with gathering this data.

If 100 people respond and 80% who say yes have a unit with an A2, then you can start to understand that it may have something to do with it. And if people weren't so combatant about everything, gathering this data could be done with extraordinary simplicity. You just fill out a column and paste the given command and move on with your life.

Does it matter what the A* means if you can see a significant trend? There's a pattern there. Maybe the information is gathered and there is no discernible pattern whatsoever. This is a part of the scientific method and oftentimes it shows what was expected and oftentimes it shows your hypothesis was bunk. That's sort of the point.

Do they need to do it? No. Do you need to do anything? You don't have to pay your taxes, but there are consequences if you don't, but you technically don't have to do anything. It's the people who do who end up actually being successful and better people.

Seems to me the OP is being reasonable, and some of those attacking the reasonability of this effort to gather data are not. If you have some info that bears on the matter of revisions, that's helpful, but all the noise not so much.

If there's nothing to the idea of the different numbers representing revisions, this will help establish that. Dates will also help indicate whether any changes have occurred. One or two perceived exceptions aren't enough, given how differently people perceive the phenomenon.

My own suspicion is that Apple hasn't done anything about this, and probably won't, but that individual screens do vary enough to be significant for some users, as the Notebook Check response time numbers from 2016 strongly suggest.

These are all guesses anyways. Unless you are an Apple supply chain manager, which none of us are. So, l
I have LP160WT1-SJA2, 2019-28-10, i have little ghosting (worst then my old 13" 2016) and for my big text smearing (im a sensitive to this and on my old 13" i dont see nothing)

Please add to tab i cant edit it.
Added. Thanks for your positive contribution!

The manufacture date of the panel, or the manufacture date of the MacBook Pro? If these numbers signify batches, it's possible that a panel from an earlier batch ended up in a later MacBook Pro.

Edit: Must be the manufacture date of the MacBook Pro, as it doesn't look like anyone has found a way to get a manufacture date for the panel.

The problem with these sort of inquests is that not everybody knows what they're looking for or even notice it when they do. Therefor results are often skewed. What this thread (and others like it) need are clear examples of the perceived phenomenon or lack thereof. I suggest participants making and posting photos or videos of their screens in this thread. That way the community can better judge the problem rather than having to take mere yes/no answers at face value.

I'm not attacking it, I'm just claiming its flawed and dishonest. The OP is only adding the numbers that fit with what he wants it to look like and ignoring the ones that don't work for his hypothesis. If he's going to run a WiKi on this then put all the data points in and don't ignore the ones that you don't like.

I'm confused. The table has at least one entry that says it doesn't have any issues. How do you think they're cherry picking? I may misunderstand what you're getting at, but on face value I'm not quite sure where that accusation came from.

I don't know how to edit the table, but I am on my third device now, LP160WT1-SJA1 - Manufactured 2019-10-21 - Panel ist far better than the previous ones, ghosting not apparent anymore.

I am pretty skeptical that there are even differences between models and it's not just people perceiving things differently, but having some people claim to get better ones after an exchange is interesting. For what it's worth, I have LP160WT1-SJA1 and I don't feel it has any of the problems.

I have a LP160WT1-SJA1 one and it has significant ghosting compared to my 2015 15". It is quite bad when the panel is cold. Much less so when it has warmed up a bit, even gets close to my 2015 15" when in a hot environment.

Mine was manufactured the 21st of October.

For what it's worth every panel I tried across 4 16" MBPs and a 2018 15" MBP looks pretty much identical to the photos above ^ but I only know the SJA code for the 4th one ?

Thanks brokenpc! Interesting datapoint for sure.

I have the LP160WT1-SJA2 and don't notice any ghosting. I do notice text smearing, but I don't think it affects anything in a way that would make me consider returning the unit. Added my info into the table as well.

Hello,

LP160WT1-SJA1 panel here. Production week : 43 (October). I have both ghosting, as well as text smearing. It give give me headache.

Just check today at my local Apple store, less text smearing as mine.

Will test a new one before my return date.

Sorry to necropost, but has anyone had any success with AppleCare replacing their panel and getting one that was significantly better? We have the SJA3 panel, machine manufactured mid-June 2020 and it ghosts to the point where it's nauseating for my wife.

We had a busy 30 days after the purchase and we weren't able to discover the ghosting issue until after the return period (used an external monitor and then discovered it when we took it mobile).

In case anyone cares, I just had the display replaced on my 2019 16" via AC+ and the replacement panel is LP160WT1-SJB1

For What its worth I own a 14" 120Hz Asus OLED Laptop with a 2K Display its Gorgeous. and a M3 Pro 14" Both displays are beautiful.
When I run the UFO Ghosting or Blur Test. The MacBook Pro M3 leaves a Blur or Smear thats Is Simply NOT there on the OLED. And if you could see this in person it is undeniable. Which is why Apple is switching to OLED.
