So I just had a "chat" with an LG Representative. I used the LG model 38UC99 as an entree to conduct the discussion but it will cost $500 more for less resolution albeit with a much larger screen. Here is a transcript of our conversation:
Duane: Hello SaratogaLefty. Welcome to LG Electronics U.S.A. Support only. How may I provide you with excellent service today?
SaratogaLefty: I'd like to know how the 38UC99-W monitor compares with the 27MD5KA-B.AUSA LG Apple Monitor? Can you tell me why the LG Apple monitor (27MD5KA-B.AUSA ) is not available for order yet from Apple? I'm wondering if the 38UC99-W is a good substitute for the Apple/LG Monitor? Will the 38UC99-W provide enough charging power (85 watts) for the new MacBook Pro Laptops?
Duane: yes as the 27 md5ka will be released by apple on either within the 2nd week or the next week after that
SaratogaLefty: I'm not sure what date you are referring to by the "2nd week or the next week after that"? Will I be able to order before 12/31 when the Apple 25% discount expires?
Duane: I apologize but the only information we have was that it was to be released by Apple on December and have estimated that is should be available around the 2nd or 3rd week of December
SaratogaLefty: So we are already in the second week of December. Are you saying this week or next week latest?
Duane: yes that is correct. for the charging capabilities it was around capable of 85 watts enough to charge the mac
SaratogaLefty: Okay great! Now is the 38UC99-W a good alternative for the new MacBook Pro or should I stick with the 27MD5KA-B.AUSA?
Duane: but hold on I m double checking that
Duane: yes as the 38" screen makes up for the loss of resolution as the 38uc99 is WQHD monitor in which has a resolution nearby or almost 4k at 3840x1600
Duane: and the only difference with the 27md5ka is the 5k resolution
Duane: on our recommendation
Duane: it's either the 27ud88 with usb type as well or the 38uc99 as the best possible substiturte
SaratogaLefty: But the Apple/LG also has Thunderbolt 3 and USB-C; I don't think the 38UC99 has those capabilities, correct? Sounds like the 27UD88 is a better fit for the MacBook Pro overall, agreed?
Duane: the 38uc99 has a usb type c port that will work with Thunderbolt 3.0 as well
SaratogaLefty: Okay, thank you very much for your help. I will wait another week to see what happens. Do you have any idea why the holdup by Apple?
He didn't know why Apple is holding up accepting orders. He said LG is ready to ship. Hopefully we will see the site open up sometime this week or next.
