Macs don't have LED displays, no laptops have LED displays. LED/uLED/mLED displays are still a few years off. Macs have LCD displays with LED back lights. You do understand that right?

SoCalReviews posted about OLED. My post was a reply to his. You can tell because I quoted his post.

Are we missing something here? An "LED TV" is a large LCD display with LED back lighting. It was simply a marketing change of words to differentiate it from LCD TVs that used florescent back lighting. Macs also are using LCD displays with LED back lighting which is basically the same technology as what is referred to in that link as an "LED TV" and of course OLED technology is something very different.

Why don't you re-read the thread, I quoted your Samsing link about LCD displays and gave a link to another web page by Samsung about LCD displays which contradicted yours. And then you replied saying your post was talking about LED displays (which don't exist) not LCD displays.
 
If you are using Dark Mode for a while.

Now go to System Settings -> General, choose Hide System Menu Bar Automatically, then change your desktop wallpaper to pure stone color (the color is predefined in wallpaper app).

Now, can you see the screen burning?

Mine is taken by an iPhone 6s Plus from an iMac 5K 2014 late.

On the bright side, if you change back to Light mode, after some time, the burning will get better. However, I don't know if it will be cured at last.

I followed your instructions and do not observe this problem. I've been using "Dark Mode" in Mojave since release day on a '15 MBP DG which I realize is not a 27" 5k display. The MBP is used approximately 8-10 hours per day and most of the time it is plugged into a charger so it's less likely to enter power savings and shut the display off. I just thought I would give some feedback if it becomes more prevalent. Perhaps, it's just with particular models, always-on displays, and so forth.

You've lost all credibility with this post. You obviously don't understand common language used to describe displays. I told you that the one post was a typing error where I was trying to refer to the general marketing term "LED". I technically meant LCD with LED back lighting but I simply used the word LED which is the common one word term used for non-florescent LED backlit LCD displays used on LED branded televisions and LED branded monitors. Yes LED is a legitimate term in the industry to describe consumer LCD screens for televisions and monitors that are backlit with LED lighting.

I also need to correct you regarding what are saying regarding true LED displays (not the marketing term used to describe LCD backlit with LED). Actually full LED (Light Emitting Diode) displays do in fact exist and they are still being used. They have existed for a very long time... decades in fact...and they were the first displays used on calculators, watches and other devices before LCD displays became common and they are still being used as displays in certain applications. It just isn't a display technology that is currently common in the consumer market for computer monitors and televisions.

Howard2k's post clearly showed he didn't understand that what the market calls an 'LED Display' and an LCD display with LED backlight are the same, he said "The article I quoted is about LED, not LCD.", so you using marketing terms like 'LED Display' is not helpful and is incorrect when discussing technical topics.

Yes I know you can get things like 7 segment LEDs but we are talking about laptop and computer monitors in this topic, find me a laptop or computer monitor that uses an LED/uLED/mLED display, high resolution LED displays don't exist yet.

Apologies, I shouldn't have assumed you knew how web forums work. My post was a reply to another post. So someone out on the Internet wrote a post, and then I made a reply to that person's post. My content is therefore related to that poster's content. It's like if you said "I like all chocolate bars" and I said "What about Snickers?". Snickers being a reference to chocolate.

Here, I marked up the posts for you so you can see which part is the part that SoCalReview wrote, and which part I wrote.

So as you can see, inside the black box is the text that I am replying to. And then inside the red box is my text, my reply. So my reply, in the red box, is related to what SoCalReviews wrote, which is in the black box.

Whenever you're confused or you think that a post absolutely has to be about you, it's worth reading both the reply (i.e., what I wrote, in the red box) and then the post I am replying too, for context (in the black box).


It's totally ok for there to be posts that are not about you or related to you. That happens. Please don't take it personally.

In this case, my post was about the use of the term Burn In. You can see that here:

It doesn't matter that you were not replying to me, my reply was related to the content of your post.
You posted a link to a Samsung web page about LCDs and I replied to you to point out that your link was not a reliable source and that other Samsung web pages contained contradictory information. This is how forums work, multiple people are involved in the conversation, if somebody posts a link to an unreliable website then anyone can point that out. If you want to have a 1-1 conversation then stick to PMs.

Not sure why you quoted that post of mine either, as that was referring to a different comment of yours where you said that what Samsung call an LED display is different to an LCD display You said:

The article I quoted is about LED, not LCD.

But the link WAS to an article about LCD displays.

I started seeing some fairly severe image retention on my iMac after updating to Mojave — as far as I can tell, it’s some sort of software issue but I wasn’t able to determine specifics. I later did a clean install to High Sierra and the problem has not reoccurred.

Yes, an "LED Display" screen is technically not what it is. It's true that it's more of a common use marketing term than a technical description so that's a fair point... and technically speaking older technology LED displays aren't really used currently for modern consumer computer monitor screens. It's just that if you wanted to be picky about language semantics then IMO your definitive reply in that post about "LED displays" not existing also didn't help in respect to this technical topic.
