I'm running two 5K displays plus MBP screen so that might make it worse for me. According to istat it's the GPU that's needing extra cooling which makes sense. It is pushing around 35 megapixels!

I normally run 2(one being returned to LG after them sending it back to me no working after shielding recall) and for my normal simple stuff the laptop is far quieter... but I am just web browsing till I get my second one back...

with 2 yes the fans go but they are two massive screens so what do you expect...
 
As @jmaluso said, there is a lot of information here! So, let's summarise the issues and bugs discovered so far, their present state of resolution, and whether they appear to be one offs, widespread, or design flaws.
  • Flickering when close to EM interference; fixed with hardware change
  • Metal stand will force MacBook Pro to sleep when in clamshell mode and in close proximity; not fixed
  • Sleep/wake issues; largely fixed in 10.12.3, but still persisting for some
  • Large stuck cursor; not fixed
  • Stupid volume scale; not fixed
  • Sluggish brightness adjustment; fixed in 10.12.4 beta
  • Unable to change brightness of more than one UltraFine display using the keyboard; not fixed
  • Unable to change brightness using Control+Brightness slider/button unless via the expanded Control Strip; not fixed
  • Non-functional ambient light sensor; not fixed
  • Slow downstream USB speeds with storage devices; not fixed
  • Slow downstream USB speeds with ethernet adapters; fixed with better Realtek drivers
  • Insufficient power output for 15" MacBook Pro (around 62W instead of 85W); not fixed
  • USB storage devices occasionally not re-mounting upon wake from sleep; not fixed
  • USB storage devices occasionally un-mounting during Time Machine backups; probably fixed

  • Spinning disk USB storage devices stay powered-up when MacBook disconnected; not fixed
  • Drop-out of camera and microphone during Skype calls; not fixed
  • Kernel panics and spontaneous reboots; not fixed
Yeah, not a great performance from LG.

Perhaps now with some strike throughs?:

I purchased this monitor from Apple online and am outside the return window. We're having most of the same problems already discussed here (Wi-Fi shielding is a problem, wake/sleep issues, causes new 13 & 15 TB MBP to occasionally freeze up requiring reboot, etc.). Are others here having success with swaps or returns (with refund) when outside the return window via Apple?

I contacted Apple care 3 days ago and the person I talked to at first seemed so willing to help, said he talked to our local store who was going to get back to me the next day (which was 3 days ago), and after two emails and two more days it's nothing but but radio silence. It's like they've been told to ignore me and hope I'll go away.

LG says they'll try to fix it but requires us to ship it back and be without a monitor for 2 weeks. Not something I want to do. Any suggestions on the best path to get a swap or refund appreciated?

Thanks

I can only praise the support I have received from my local Apple Store for this product. They have gone well beyond what I would consider even 'good' customer service. I would suggest calling AppleCare again and ask them to escalate this to a manager. Ideally do that during the opening hours of your Apple Store so they have a chance to talk to the store staff if necessary to arrange an appointment. I wish you good luck, these displays are great when you get a good one! :)

For me I don't think the volume scale is a problem, at least not when controlled via the Apple midi app.

Kernel panics and reboots seem to be less of a problem now but that might be due to me running the latest developer beta of 10.12.4.
 
I get sleep/wake issues, also flickering cursor or gfx glitches and the usb needs to be replugged in each time as well.

702/10.12.3/13"TB
 
I had loads of problems until I started to just make sure I opened the laptop before connecting and reconnecting as it states on the apple website... most of my problems have gone now except LG sending me back a broken monitor after sending it back to them working...
 
in all honesty I can not remember the link and don't have the time to search...

never seen that link... I think I must have searched external screens and MacBook...
That sounds like something Donald Trump might say! :p

Please don't take offence, genuinely kidding. :)
 
I think I do what scott_donald says anyway...

- If working on MBP + 2x 5K's, but want to break away:
Just unplug the two cables going into the MBP in one go. All windows from 5K's appear on MBP.

- If working on MBP, but want to reconnect to 2x 5K's:
Have the MBP awake, replug the two cables from the 5K's into the MBP in one go (Touch-ID to login, if necessary). All open windows (that were on the 5K's previously before unplugging) will appear back where they were on the 5K's.**

**Except when they sometimes appear on the wrong screen (left windows on the right, and vice versa) – I suppose you can't have it all, lol! :-|

I'll wait until the full version of ".4" is released before, updating those two, but thanks.

BTW, when you say the volume scale isn't a problem, I presume you mean the in-app volume control when using Multi-Output Device or Aggregate Device in Audio MIDI Setup, as opposed to the system-wide one which is greyed-out in both the menu bar and the sound sys pref pane?

I have sleep wake issues with normal monitors and what I do that seems to help is put the computer to sleep before disconnecting.

Yeah I guess it's still not ideal when you switch to one of the displays directly. If I adjust the volume from the Touch Bar 1 bar is very quiet, 2 is pretty good but 3 is a bit too loud and there are a bunch of segments after that which are even louder obviously. What I would say though is that the sound quality is good with no signs of distortion even at high volume and I'm pretty sure my old displays were not like that. I think they distorted about 3 or 4 segments.

Regarding plugging both displays in at the same time, I'm not sure that's actually the best plan. I forget which thread I mentioned this on but after several days of my setup working flawlessly, I had cause to unplug my laptop from the displays and use it in another room for an hour. When I went back, I plugged both cables in literally together at the same moment and it did the usual sync process before both displays lit up. After that, for several hours I was seeing symptoms of the WiFi interference issue even though I'm running 702 displays and my router hasn't moved.

So, last night I unplugged both cables and then plugged them in one at a time, allowing the first display to sync before plugging in the second and ever since then it has been working flawlessly again. So I wonder if the act of plugging both displays in at the same time is somehow causing a problem to persist? It might be circumstantial but I thought I'd share anyway.
 
I have been avoiding sleep/wake issues by simply making sure the Mac is awake before unplugging it from the monitor. Not had any issues since doing that.

I only ever go one at a time...

funny one to try is use an Apple TV when 2 are plugged in... disconnect then I get some bizarre occurrences...

"Insufficient power output for 15" MacBook Pro (around 62W instead of 85W); not fixed"

I think it's been proven that the cable is an active cable, meaning 60w. Someone was able to get 85w using a 0.5 passive TB3 100w passive cable.

I don't think that first bit is true. As the whole point of the active 2m cable LG are supplying with the 5K's is that it offers proper charging at 85W, versus the worse (active?) Belkin 2m one that only offers 60W, hence is not advisable to use with these displays.

The Sys Info "Power" section on my 15" MBP connected to my two 5k's is showing:

AC Charger Information:
Connected: Yes
Wattage (W): 85
Charging: No


So it does provide power at 85W (it's not charging, as the MBP is at 100%).

Does any other 15" owner still have this issue or can this point be crossed out now?

My bad, I got active cables mixed up with not having USB 3.1.

There's been mixed reports about the LG 5K not providing enough power. MKBHDs laptop was draining while rendering.

There's a review on Amazon stating that caldigit's 100w TB3 cable can provide full power through the LG 5K

The system report has shown to be misleading, so I wouldn't take it as gospel.

Agreed
 
The charging issue can be tested using the method I explained previously (and is copied below). Anyone with 20 minutes to spare and a 15" Pro and 5K display could give it a go.

If you find yourself at a loose end for 20 minutes and fancy investigating it, you could run your MacBook to a state of medium-low charge (anything under 70%) and increase the power consumption to the absolute maximum by simultaneously thrashing it with:
  • four instances of the yes command in Terminal
  • GpuTest's stress test
  • brightness on maximum
And use coconutBattery to compare the "charging with" figure under the LG 5K charger, and the Apple charger, to see if the Apple charger shows a higher charging current (or, if Marques is to be believed, a lower discharge current).

After previously having to return both an LG 4K and LG 5k for shoddy manufacture, Apple's response to my inquiries regarding procuring a properly manufactured LG 5K monitor were pathetic. On Sunday, in an attempt to avoid a panel lottery in procuring a 703 manufactured LG 5K by ordering online, I called Apple's Mall of America store in Bloomington, MN to inquire if the store had any stock and, if so, if any were 703 units. The Apple sales person was very unhelpful and I was informed that units were in stock but he would not tell me how many or if any of the units were 703's. That is, the sales person could not walk 50 feet to check his stock but he thought it a perfectly acceptable alternative for me to drive nearly 20 miles, each way, to check it out for myself.

This, to me, was "the straw that broke the camel's back". Because this whole ordeal with LG's 4K and 5K monitors has been such a pain, I called Apple to register my disapproval of this shoddy customer service at the Mall of America store. The Apple representative who answered the call was very helpful and offered to call the Apple Mall of America store to contact the store manager to inform him/her of the poor service the store provided and get the information I was seeking. The Apple representative called the Apple Mall of America store twice: On BOTH attempts to call the Mall of America store, the Apple representative said that the store picked up the phone call and promptly HUNG UP ON HER! At this point, we completed a complaint regarding this poor service and generated an Apple case number that was to be forwarded to management at Apple's Mall of America store who, in turn, was supposed to follow up and contact me. Well, nearly 48 hours later, I have yet to receive the requested call.

Accordingly, today I just went ahead and ordered an Eizo EV2750-no 5K or USB-C inputs but has very solid reviews, manufactured in Japan (NOT in China!) and a 5 year warranty. I will connect it to my late 2016 15" MBP with a USB-C to DisplayPort adapter and be done with this USB-C option limiting nonsense. Since this monitor has HDMI, DVI-D and DisplayPort inputs and USB-C outputs, it should have connectability for the foreseeable future.

Apple is just not what it used to be: Since the early 1990s, I have always been willing to pay the "Apple premium" for reliable, innovative products and great customer service. Sadly, none of these attributes are apparently priorities at Apple today and purchasing the Eizo monitor represents for me, after 25+ years, just the beginning of my efforts to look elsewhere for quality computer products and services.

Yeah, Apple can be hit and miss in CS terms, especially recently. I got told I couldn't return my original two 612 5K's after two new replacement ones arrived. So I simply hung-up, and a week later ordered two new ones which arrived a couple of weeks later (turned out luckily to be 702's).

They worked much better, then I re-phoned Apple and asked again to return the original two; no problems whatsoever, after getting quick mgr permission to do so?!

Left hand not talking to right hand, seemingly.
 
I talked to Apple CS and they won't sell you specific serial numbers. What I had to do was keep exchanging/returning until I got one with shielding. It was a big pain, but I finally got one with shielding and it's an excellent monitor.
 
Apple has been poorly positioned to handle this fairly large influx of 3rd party purchases. I recently received the 703s which are performing pretty well and no issues to report as of yet. with the exception of the outstanding glitches;

• Volume adjustment, it seems to be somewhat tamer than the previous sets I've had, maybe since I haven't had them hooked up in a while Im not noticing it as much.

• Slow brightness increase/decrease (I can change both monitors using control+brightness)

• Cursor sticking when moving

• Sometimes the MacBook will be shutdown after going to sleep

• Sometimes the system will crash when in sleep mode and either waking it up or unplugging it. rarely but it has happened.

I had to escalate the first few sets to Apple CR as they wanted me to exchange through LG (when I phoned them they had no idea what I was talking about and almost sent someone to fix a kitchen appliance??) and Apple initially stated I could not exchange them after the 2nd set...then thats when most people started providing Apple feedback and I was able to get the "exception" to exchange them when the new units arrived. The Apple CR handled it pretty diligently, after Apple Store online sort of gave me the run around and had issues with some of their team, apple retail referred me back to AOS, which is fine as I'd rather not commute far to the stores these days anyway.

So far so good, hoping some of these outstanding items get resolved via software. And if Apple truly is leaving the desktop display business, atleast open up the options to other Manufactures to all software adjustments of the display settings.
 
I had the reverse-shielding problem. The LG 5K monitor was causing very loud audio noise on my speakers. I have a long established setup with 2 NEC monitors, MBP late 2016, Mac mini, occasional other PCs and a small TV all connected to a Rolls MX44s audio mixer and HK Soundsticks. with never a problem for years. When I added the LG as the third, but main monitor, I started getting loud static on the audio system. I moved devices and wires all over the place without improvement. Interestingly, I could greatly reduce the noise if I plugged the apple power adapter in to the MBP (it then would seem to power from their instead of the monitor). It seems like reducing the load on the monitor's internal power supply mostly reduced the noise. Also, the noise appears for several seconds every time the monitor powers up.

I returned the monitor for the shielding update and the issue seems to have improved, maybe by half, but not disappeared. One particular audio input to the mixer (Mac mini) seems the most affected, so I pulled its fader way down and its volume up and that has helped.

Sadly, now that the monitor is back after being gone for more than a week, I discovered that the microphone is no longer functional. The repair order did not mention a shield upgrade at all, but did say they replaced gaskets and replaced the camera module for some reason.

The Mac allows you select the internal mic but detects no sound. The internal speakers still work (super hot volume) but the mic appears dead. Has anyone else seen any of these issues?
