This 27-inch display is exclusively designed “for computers and tablets from Apple” is the primary official 5K display Apple. Officially, there are three options – in fact four. It’s not the only mystery of these displays.
In 2016, when Apple discontinued sales of 27-inch Thunderbolt Display, the product range of the company there has been a gaping void. No, those who required a 27-inch external display without any problems could acquire it on the side, but it was criticized by outsiders of the merits of “native” monitors from Apple demand from users and Macs are not useless. But the gaping emptiness did not last long at WWDC 2016 Phil Schiller recommended a great solution to this problem. He didn’t LG UltraFine, not a word is said about what is a joint development of Apple and LG Display-and did not disclose any details, but all who were interested could look in Apple’s online store and learn about everything yourself.
With LG UltraFine 4K all turned out very well. The problem, of course, was but very little, easily solved by the technical support services of both companies. But at 5K, unexpectedly, revealed a very nasty drawback. Which was not detected at the testing stage. The protective coating of the electronics of the display was not powerful enough, and if the display was at a small distance from the WiFi router, the image on the screen of the LG UltraFine 5K is distorted by the interference. No one had not occurred to expose the display such tests, an ordinary case. The problem was quickly solved, already in 2016, but because of the obsessive secrecy of both companies any other: buying LG UltraFine 5K on the secondary market easily can become the owner of the display with insufficient protection.
The risk group includes displays released until November 2016, or more precisely to determine the date from which all LG UltraFine 5K are equipped with fixed interference protection failed. Those who are faced with this problem, displays have replaced free of charge. I don’t know if this was the problem in my instance it was about ten meters from the router and worked fine. I used it for several months, starting in October 2016. Therefore, the first version of the LG UltraFine 5K (27MD5KA-B), produced in 2016 and first half 2017, I consider two variants – variants “at risk” and “outside”. As about the display I don’t remember any claims to it was not.
Model 2019 (27MD5KL-B)
If Apple and LG wanted to organize for those who are going to buy a 27-inch Apple display from LG for a little adventure, I have to admit they succeeded. In spring (April) in the commercial Apple suddenly disappeared from the sale of the 27-inch LG UltraFine. First, they were not in stock, then they were removed from the lists of available peripherals. Amid speculation about a stunning display worked in the Apple it looked promising, until in June of this mysterious display shook the public’s imagination with its performance, and price. The adventure turned into a Thriller, the tension increased, until at the end of July, without the noise and dust, on the shelves of the online Apple store, and its partners, not a new 27-inch display from Apple and LG.
Technical data compared to the previous two models on display, had not changed. It is obvious that changes in firmware were significant, but that none of the responsible for the product of the parties says. Opportunities LG UltraFine 5K was more, he learned to work with “tablets from Apple” – a quote from the Apple website, in fact, currently supports only iPad Pro with built-in USB-C. the Third generation, released in 2017, with iOS 12.4 or higher. The mysterious feature that a lot of writing, including official sources.

Maximum brightness of 500 CD/m, contrast ratio – 1200:1 (according to some sources – 1100:1), housing four sockets, one USB-C (Thunderbolt 3) and three USB-C (5 GB/s). Due to the fact that only one Thunderbolt port, Daisy-chaining of several displays is impossible in principle. The USB-C port can connect all kinds of peripherals. Connected display device is charged from him (94 Watts).

First the 27-inch LG UltraFine released in 2016, was officially called 27MD5KA-B. Displays the problematic interference protection and with adequate protection meant the same. In 2017, LG released a model with the designation 27MD5KB-B, in the official specs which had no difference from 27MD5KA-B. Naturally, the question of how these models differ from one another and asked Apple, and LG. Most often there was no answer at all, sometimes have reported that it’s just a new version, LG announced that if the new model is to buy on some other channels (actually, the only distribution channel for LG UltraFine is a trading Apple) purchased are warranted for 3 years. My friends, intending himself to find out what version of the display differ from one another, acquired in early 2018 this display. But the answer to your question they found. Delivered them to the display was 27MD5KA-B.
