I just realized I took a photo of my display before I send it back. Had a square! Too bad it wouldn't turn on 13 days in.Just posted my box label AND display back pix on that thread, to help others see differences.
Got a tip for us?

My 612 unit has the black Circle. No interference (18" from Time Capsule) but going back as I dont want a refurb when I paid for new. I do have issues with waking from sleep when plugged into the monitor and have to unplug or even hard reboot sometimes.
I never had issues with my screens, both 701 received in Early March. Just checked the photos I took of the serial numbers and they both have the black sticker.
I really like this setup a lot. Fantastic screens!

Glad I didn't fall for the discount trick and invest $1000 in this monitor, because it's the end of March and no sign of a 32gb laptop to replace their non existing 27" 5k update. I would have had a monitor i couldn't use unless i put down 4k$ for a 16gb laptop that i dont really want right now.
"a 32gb laptop to replace their...27" 5k"
Erm, wot? A laptop is not a desktop and vice versa. But never mind.
And if you don't want one right now, then just wait til you, erm, DO want one.
Some real f'd up thinking you have there.

lol, I went through 6 MBP, I had one that didn't power up out of the box and wouldn't hold a charge after being hooked to power cable. A few had terrible green/pink/yellow hues and another the touch bar was not working properly.

So I gave the LG 5k a bad rep when I blamed it for not turning on (the lightning cable would power the MacBook but the display stayed off). Upon receiving my latest replacement (703, black square) it still wouldn't turn on. I did some further troubleshooting and reset the SMC...magic. It turns on now.
I had been having trouble with my USB-C ports not powering an external hard drive with the Apple-branded USB-C to USB -A adapter. It only worked with a cheap adapter off eBay. Turns out it was a software issue this whole time.
Well I'm pleased to say I have everything work. Bonus: this latest monitor has better colour temperature than my previous i.e. more cold than super warm.
Well, if I invest $4000 in an iMac, and they don't release one. then everybody here goes "why not buy the macbook pro then?" .. well for $4000 the macbook pro only comes with 16gb ram and a gpu i am not happy with.
it's the only thing they've renewed in 2 years .. and it's not even close to what i want out of an imac.
and the point was that i agree, they can't be compared, ergo, a waste of money.. i dont want the laptop.
Are your MacBooks warm to touch after leaving it to sleep for a while? Say, when I wake up in the morning, the chassis is rather warm - probably warmer than when I'm actually using it (as the fans aren't on).
The machine is definitely asleep, since the fans aren't running. Just being a little power usage conscious.
With a 'dumb' DisplayPort screen, this never happened. With the same USB-C accessories attached directly to the MBP, it wasn't either.

Received the two replacement LG 5Ks, 703s with black square, they seemed to be more fluid when connecting and not kernel panicking the Mac.
Brightness is still somewhat a little stutters when adjusting but better than before, volume adjustment is fluid and not insanely loud on only two notches.
The only issue I found thus far I see the small bit of light bleed on one of the displays. They're both very similar to the 5k iMac, each has a nice cool color and are pretty accurate out of the box without much calibration.
One other thing they can fix is the styrofoam that seams to crumble when taking out the displays, otherwise nice improvement and looking to see who the last during the next few days.

Has anyone considered that the issue lies not with the LG display but with the Mac for a majority of these issues? Seems like most of the frustration is directed at LG when it should be toward Apple. If you're having panics, issues with brightness / volume adjustment, peripheral connections, etc, chat with an Apple Support member (ask to have your case elevated) and they'll do a data capture and forward the information to engineers. If enough people do such, it'll lessen the time it takes to get a lot of these issues fixed.
Interesting you say that - my 2016 15" MBPtb and twin LG 5k setup has been behaving really well for a few days during which time I have not disconnected the laptop from the two displays. I even commented on one of the 5k related forum threads to that effect yesterday. However, this morning I disconnected the laptop from the displays for an hour to work in another room and now I've connected them back up, I'm getting regular screen sync problems where it drops out and reconnects a few seconds later etc. These are both 702 displays with the black square and my Time Capsule router has been sitting in the same place for over a week so I think this is not necessarily a WiFi interference problem I'm seeing now. It could be cable connection related or perhaps disconnecting and reconnecting causes some sort of software state issue or perhaps upsets the LG display in some way.
To try to get to the bottom of this, I'm going to try a few things such as doing a fresh reboot while displays remain connected and then see if it reliable thereafter. Then if it is then I'll try the disconnect/reconnect and see what effect that has. If I feel I have a reproducible issue then I can escalate with Apple.
I did it yesterday and the senior advisor forwarded the issue to the engineering team (at least that's what I was told). One my laptop (15 inch TB), the connectivity issues with the USB-C ports of the screen are totally reproducible. I would not be surprised at all if the issue was due to the Mac as I sometimes have issues with just connecting a keyboard to one the computer's ports.
^I have updated the great "Issues/Bugs" thread list that Brookzy did, here: #452.
If you think something should/shouldn't be striked through, consider contributing on that thread, and I'll update.
I've got mine 5K for a week now nad I have found another strange behaviour. When I'm connecting display to the usb-c port on the left side fans are loud (3200-3800 rpm and gpu temp is 60-65C) but on the right side everything is ok, fans speed is 2100-2400 rpm and gpu temp is the same 60-65C. Now I don't know if there is something wrong with display, macbook or macOS? I know it is not a big bug but hate loud fans noise and can't work on mouse with cable on the right side
Do you have simmilar behaviour with yours LG+MacBook Pro 15"?

Haven't played around but it's probably just that there's more heat generating circuitry on the left (CPU, GPU, etc) and when you also charge through those ports, the heat isn't spread as evenly across the computer and the fans kick in to lower the temp.

I have this also its quite weird but it doesn't affect performance in any way.
Absolutely, I suspect a lot of these issues are software related, and macOS in particular. I get the feeling the Thunderbolt 3 drivers are not completely polished yet, given all of the USB hub wonkiness, and the graphics corruption issues a few have seen (including myself one morning) also point to teething problems with the AMD Polaris drivers too.
Interesting observation. Check this out, I reckon it's because the dedicated AMD GPU is on the left side of the logic board.

The fans work fairly hard on my MacBook when running both 5Ks, it's got to be fairly GPU intensive to push so many pixels. Hopefully Apple have designed this thermal system to be able to handle that load constantly for many years to come!
I got my replacement and it's a 703! with a black square.
I tested it with my router and I was unable to cause interference. I'm a happy camper.
Are you located in the US? I got my replacement and its a 701 with a black circle

I'm in the US.
Before I got a 703, I had 612, 612, and 701. I returned them all, but that was before discovering what the circle and squares mean. If I would have known, I probably would have kept the 701.
I posted a profile for both the MacBook Pro 15" and the 5k, other than that you'll have to make one yourself with a profiler.
To illustrate the connectivity issues of the USB-C ports of the LG 5K screen, I produced this little clip:
Yeah that reproduces the effect I see with an external hard drive connected to the USB-C ports on the display. In order for it to work, the hard drive has to be the last thing to be connected. I think this may be consequence of some features of the protocol used on this interface because I've heard similar things about power transfer between peripherals where the direction of power flow depends on the sequence of connecting things up. Like, even with a USB-C to USB-C cable, if you connect it to computer first then peripheral it has a different effect to what happens if you connect it to peripheral first then computer. I'm sure there will be a way to override whatever way it is currently working and I expect LG just need to update the firmware to make it do this. That all said, you'd think they might have tested this sort of thing...
