It is up to that if one appreciate OLED like blacks and uses the machine in the situations (dim or dark room) where that shows the best, then Mini LED is better. Otherwise it may not matter so much, especially if not used to OLED like black levels already.Fair enough. But newer tech doesn't necessarily mean it's better, just different
It is a great laptop and I am sure you will enjoy it! The screen is great and bright!Fair enough. But newer tech doesn't necessarily mean it's better, just different
It is fast and light. Overall just a great laptop!
No, my 77" OLED does not, however blooming in my MBP 14" rarely shows in dark even because I don't use it that bright settings then where is would became possible to see. However where MBP 14" beats the s**t out of 77" OLED (and other sizes too) is around 5% gray uniformity. Just fire up suitable test pattern in dark room on both of them and OLED makes you cry (at least it makes me). So both have their strengths but black level in generally is about equal between the two in most situations.
Edit. Thanks for giggles Joan.

I am not sure if this is serious? I would call Apple if you think you are having problems that you can’t resolve. Maybe have them run remote diagnostics to check for hardware issues.
All laptops can crash and two times in what time frame? Is it continuing?
But if you are in a return window that is an option.
If you don’t use it for “that bright settings” then what’s the point of a 1500 peak nit screen?
Genuinely curious.
That bright hurts my eye, but that is just me, I don't use my OLED at max. brightness either.
Anyway even OLED is not perfect IMHO, this drives me crazy: https://www.avsforum.com/threads/oled-screen-uniformity-discussion-banding-and-vignetting.2896737/
Offtopic, Joan please giggle. I love to hear your giggling.
hence i said closest, not exact. i haven't even notice any blooming issues, so maybe you might wanna get yours checked out. but besides the blooming, its still miles better than old tech like ips.
sure, but not in this scenario, mini led addresses alot of shortcoming from ips.Fair enough. But newer tech doesn't necessarily mean it's better, just different
As I said, fair enough. I think this is an endless discussion as everybody has different expectations
You do know that mini led use ips display right? It is not OLED or emissive and mini led uses a backlight.
Mini led is ips it is just how the ips display is backlit.
So calling ips old tech is also calling mini led old tech.
That brings us to a subgenre of LED displays, Mini LED. Since all Mini LED displays are LED displays, all Mini LED displays are also LCDs. Everything we've said so far applies to Mini LED displays.
- Mini LED is a step below Micro LED, (which is nearly impossible to find in a consumer display), and it's two steps below OLED in terms of contrast-boosting image quality.
- Mini LED displays can suffer from the halo effect, or blooming, due to local dimming.
The main difference between IPS and Mini Led is how many zones are backlit. Micro Led which I hope Apple starts to put into their displays eventually will be close to OLED but have much less of a blooming effect. IPS displays do not have as many backlit LED's to use but the LCD backlight technology is the same. You could say that Micro Led is an improvement on the backlight technology used in IPS displays.
IPS is the industry standard and has been around about as long as OLED and is considered a new technology compared to VA or TN backlight LCD panels.

Actually IPS is just the type of the LCD-panel itself but it needs some type of backlight to work. So in IPS Mini LED there is backlight LEDs right behind the LCD-panel (back lit also exist and has much lower number of LED in backlight than Mini LED), and this type of backlights have at least two subtypes - local dimming where each or certain group the LEDs can be dimmed, another is the one without local dimming (MBP 14” and 16” have local dimming type). Then the most typical is IPS Edge Lit which just has LEDs on the edge(s) of the LCD-panel (this is what is used in MBP’s before 14” and 16” (the latest 16” model) and in MBA M2 and M1). This Edge Lit LED backlight is the reason why possible light leaks appear often looking like there are flashlight at the edges of the screen.
So LCD-technology in this case is IPS but it can have then either edge lit, back lit or mini led backlight with or without local dimming (even edge lit may have local dimming but it has very limited effect due to leds on the edges only, practically can dim just rows of the panel like black bars on the movies).
Technically IPS, VA and TN are all just subtypes of the LCD-panel but they all must have separate (above mentioned) backlight to make them work. OLED and already gone Plasma are self illuminating pixels (so no backlight in those panels). LCD panels itself have their features, where IPS gives the best viewing angles of those 3 and also usually has best color accuracy, VA gives highest contrast by nature but has limitations in viewing angles, TN is the oldest type of these 3 with worst viewing angles and colors (usually) but it has its strenghts too in some situations.

In other words all of them have strengths and weaknesses and it really depends on the quality of the individual panel you are talking about so general statements like IPS is dog poop and old tech are a bit exaggerated.
Samsung still uses TFT in some of their high end tablets and they are very nice with better viewing angles and color vibrancy than some IPS displays.
It all comes down to the individual panel and quality. All displays have strengths and weaknesses. Some are clearly better in some areas and worse in others and it all comes down to personal preferences and what the individual needs/wants.
the MacBook Pro is apple's better display just like the iPhone pro and iPad Pro.
This depends on how we look at the things, true all have their strenghts and weaknesses but my statement edge lit IPS (like the one used in MBA M2/M1 or some MBP models (not in 14” and 16”)) being dog poop is correct (IMHO) because LCD panel itself cannot block all the backlight - this causes poor more or less grayish black level often with bluish or reddish tint even, and in edge lit LED lights leaks appear often looking like flashlights on the edges of the screen.
In this regard IPS Mini LED used in MBP 14” and 16” is completely different beast where is has LEDs directly behind the LCD-panel and amount of LEDs is 10000 (if I recall right) combined with local dimming. It has practically equal black level to OLED and it does not suffer from typical OLED above black uniformity issues like vB and similar what poor or nonexistent mura-correction may or may not correct at some level but not enough.
Surely Mini LED may show some blooming in certain situations with high backlight in dark room around some smaller bright objects on black background, the same situation where edge lit IPS shows washed out grayish black and possible light leaks. So in that sense edge lit is dog poop to me.
Technically TFT in generally just means Thin Film Transistor but there are not only TFT-panels, it is either IPS (TFT), VA (TFT) or TN (TFT), so that Samsung TFT is one of those, probably IPS (most likely) or VA, but it is misleading talking just about TFT-panel without mentioning which of those 3 it is. More precisely there are actually 3 different IPS-panels, IPS, PLS and ADS - but they are all more or equal IPS but marketing term is different based on manufacturer where IPS is LG’s trademark, PLS is Samsung’s and ADS is BOE’s. So ”TFT” in that Samsung tablet you was talking about might also be PLS (TFT), but definitely not just TFT as that type of panel alone does not exists (so IPS/PLS/ADS, TN or VA).
Well, LCD-panels have this weakness where they cannot block all backlight, so contrast ratio and black level is poor, unless you ”help” it with the most advanced type backlight (for example Mini LED with high amount of individual LEDs and local dimming). Of course even using the best backlight technology it does not match OLED but like I mentioned before OLED has its weaknesses (mostly that around 5% gray uniformity is the worst and I hate that feature, so in some ways MBP 14” Mini LED IPS can be even better there).

So is mini led IPS?
“In this regard IPS Mini LED used in MBP 14” you got on to say different beast because of the difference in backlight but fundamentally it is IPS which is the point I was trying to make.
You wrote a good amount 😉 there.
It can be any of those types, ips/pls/ads or VA or TN. But yeah, in case of MBP it is ips but more advanced backlight makes it better (different beast).
Yeah sorry about that and I know what you meant. Displays are my dear and painful hobby but I can’t help myself.
Forgot to mention this. IPS is pretty old innovation and has been around much longer than OLED especially if we simply look availability for consumers it was pretty much TN then IPS (about 2 decades ago) then VA and OLED the last becaming more common in past decade or so.

No worries. We write a lot about what we interested in. I get it.It can be any of those types, ips/pls/ads or VA or TN. But yeah, in case of MBP it is ips but more advanced backlight makes it better (different beast).

My point was that the underlying technology using IPS and Mini Led are the same both using an LCD and backlight.
The irony is how a lot of people are saying that IPS is old technology like it is out of date and inferior yet the new mini led is essentially the same technology. Obviously it is newer in how the backlight is controlled and how it mimics OLED but it is not an emissive display tech and will never be.
Also mini led doesn’t make IPS displays in other laptops bad just different. There are advantages to mini led for sure but there also disadvantages like blooming and until micro led tech is pushed to consumer displays those disadvantages won’t go away.
I can see how mini led has certain advantages over OLED like brightness, lack of burn in, and Oled pixel die off in the blue color spectrum.
Every flat display technology has trade offs. Nothing is perfect.
So I think it is unfair to say that a great IPS display with good color accuracy is excrement, washed out and old tech like some have said in reference to any display that is not a mini led xdr display which is in a minority of Apple displays at the moment.
IPS screens have their disadvantages no doubt like black levels, lower contrast and back light bleed but that doesn’t make them bad displays and there are some with very good contrast and very little backlight bleed with great vibrancy and color accuracy which don’t suffer some of the disadvantages of mini led or OLED displays.
VA is not better than IPS. I have had a few displays with VA and they were not very good and seem to be offered in cheaper displays.
IPS is still the industry standard and is not old in the sense that it is outdated.
OLED is the newest display tech and it is not used on any Macs.
Thanks.
In LCD-panels they they are similar but difference in Mini Led backlight and local dimming vs edge lit no local dimming in MBA and older type MBP. But there is a big difference due to this between the two IMHO and that is pretty commonly stated thing about this vs edge lit.
I did not say so, just stating the fact in which order they appeared for consumer market.
They all are industry standards, meaning tn, ips, va and oled.
I know. Some computer makers use them already but imho I’d take rather IPS mini led backlight display for computer than oled with risk of burn in and poor 5% gray uniformity and bad mura, but that is just my opinion. Oled also uses pretty strong brightness limiting for full screen white image, so it does not get so bright in that case.
I agree.
I would also say that for most people the mini led is a better screen over all. When they iron out the blooming and flicker/PWM in the mini led which I am sure they will then I think it might be the best display option out there. Also they really need to improve the screen response time on the mini led because it affects the 120hz refresh rate and causes text blur.
However it doesn’t make IPS edge lit displays bad. They are different and right now at least on some IPS displays they don’t have blooming, PWM or burn in or pixel degradation. IPS still offers great vibrancy and color accuracy with good viewing angles. So in my opinion, and it is a personal preference, regular high quality IPS edge lit displays are the best for my eyes until they get the micro led or improve on the mini led which I am sure they will.
Maybe by M3 we will have micro led screens with fast response times and that would be pretty close to perfect!
