Thanks. I'm going to go with the OWC TB3 dock and keep the Dell 4k for the one cable solution.

This is the issue that I'm dealing with. I have some Thunderbolt 2 devices. If I want to use those along with the LG 5K, I lose the one cable solution. BUT, if I return this expensive LG 5K, I feel like I may be just as happy with a 4K 27" connected to a Thunderbolt 3 Dock (when they come out). One cable and all my stuff works over it.

But I'm not sure. Can anyone tell me if you can see a big difference between 4K and 5K in a 27" display using the HIDPI mode in MacOS?

So after a very frustrating first day with the 5K display...tb mbp 13" spontaneous reboots...mbp screen flickering...5K screen flickering... black screen for minutes at a time etc....

The cause of all of this was my wifi router (Apple AE) was behind the monitor. Now I have moved it about 2 feet to the right of the monitor, with my mbp on the left...and not a single glitch in the last 5 hours of work.

We have learned that LG has no shielding on the back...so maybe a nice tin foil hat would help the display behave in close proximity to a router.

For real?

My goodness - WTF is going on w/ Apple these days..

This is the "endorsed and collaborated on monitor" and it has issues like this? (and don't get me started on the aesthetics)

I have a 2012 iMac in the same room as the LG...and I must say that the LG doesn't attract as much attention and just sort of disappears. I have mine on a dark brown IKEA desk and I think having the electronics disappear when they are not in use is actually better. Of course it definitely isn't Apple design, however now that the monitor is working, it is fantastic and clear and easy on the eyes.

Hope it lasts - I'm so irritated about my LG death/repair fee right now..

I have mine today!!! MBP 2.9/8GB Ram/Iris 550. Moment of truth - everything works great, except TERRIBLE resizing lag.

However: plot twist, I discovered that resizing lag was a SOFTWARE issue, specifically with Better Touch Tool snap areas. The moment I disabled that, everything is smooth sailing. I'm seriously impressed. This looks better than my iMac at work, plug and play with the MacBook Pro. There's some wobbling if I hit my desk, but that seems to be an issue with the monitor being at a height.

All in all, this is the best monitor I've ever used especially in conjunction with the MBP. Birds are singing over my shoulder. Testing USB ports in the back now.
[doublepost=1484697512][/doublepost]Also tbh I probably just need a less wobbly desk.

I can confirm the WIFI router issue with the 5K displays. I had a Netgear R7800 Nighthawk router on my desk, right behind the monitors. This I believe caused my first pair of displays to not even turn on. I relocated the router to about 8 feet away on the wall, and my replacement 5K displays work flawlessly. No blanking out, no flashing, no system restarts.

It was a pain to move the router as I had to run the wires through the wall, but on the plus side, the new location is providing better signal throughout my house.

can anyone tell me if I would be able to use a TB external drive with the TB to USB C adapter on the 5k's USB port?

OK, I just ordered one too. Who am I kidding. :D

The screen on my MacBook Pro 2016 is vastly superior to my Samsung SA850T 27" that I use as an external monitor, and I had the serious envy of that iMac 5K screen from the first day. It is a bit of a bummer that I can't use it with my Windows desktop, but nobody came through with a better alternative on CES 2017 - at least not a 5K monitor - so there's that. And the discount did help too. :rolleyes:

Now I just look forward to getting it! Waiting time is 2 - 4 weeks here in Denmark. :mad::D

Not sure but I had all of these same issues with my 5K monitor shipped on the first round as it arrived to me on 12/30. Mine did same things as noted above and elsewhere on this forum. Mine was returned to Apple and a replacement arrived a couple of days ago and it works flawlessly. I do have multiple wifi radio devices within 6" of the display both before and after the problem. So I would not totally believe that this is the problem for everyone that has a flickering screen or one constantly turning on and off. Thought I had a bad cable or bad cable connection. I didn't want to buy my own Belkin cable for an LG problem anyway. So decided to return my first one and the second one has been flawless in MacOS and Bootcamp/Windows. If someone has a problem I recommend return and replace.

Has anyone else noticed a yellow tinge in the corner of their display? When I have a white screen, the bottom right corner area is definitely not pure white like the rest of the display.

This should be case by case issue. My screen is pretty even as I've posted pics before.
You can try your luck and do a replacement see if it's better.

Thanks. I have requested a replacement today and it should be with me by 2-9th Feb. I have requested if I can send this one back once I receive the replacement and they agreed I can send it back by 8th Feb. Should get the replacement before then.

It is an expensive display and really annoying to see that yellow tinge in the bottom right. It is particularly noticeable when working with a white background.

Can anyone sum up for me the "docking" situation w/ this monitor?
I'm totally confused here..

What *can* you do with the rear USB ports and what are the issues here?

Ethernet dongle?

Thank you for any summary of thoughts. The thread is super long...

I have connected my microphone, speakers and time machine to the rear. A single TB cable then runs from the display to my MacBook. I have explained it in more detail in a brief review I wrote: https://andykumar.net/2017/01/12/lg-ultrafine-5k-monitor-a-brief-review/

Was a good read, thank you.

I'm also interested in three more things about this display now that it looks more and more like I am going to be buying two of them to go with the refreshed iMacs (whenever they arrive).
  1. What performance are people seeing over the USB-C ports? Especially when all three are in use (e.g. ethernet, hard drive, iPhone cable?)
  2. What cable management strategies are you employing considering there is no solution for this in the display?
  3. Does anyone have two of these displays? Does changing the brightness using an external keyboard change the brightness of both screens at the same time or just one of them?

Thank you - I was just reading that actually! ha! nice!

So with "normal/older" speakers (normal 3.5mm connector), you are sort of SOL as USB is needed?

There is no 3.5mm jack on the LG display, so you either need USB speakers or connect directly to the MBP. I have the Bowers and Wilkins MM-1s (purchased in 2010 and still lovely!) which luckily connect via USB. That's one less cable to worry about. Phew!

Thanks, mate.

Performance over USB seems to be fine. Had no problems with back-ups and data transfer speeds. Cable management is fine. I am using a desk from IKEA that has a net built under the desk, so all cables are in there and I just have a single extension lead going into the net. I am planning to post a YouTube video of my set-up soon.

You can adjust the brightness of the display using an external keyboard. I am using a Logitech K811 and it works fine (although a bit of lag/delay) but this is also the case with the Apple worlds keyboard too from what I have heard. It only changes the external display and not the MacBook, but not sure how it works with a dual external set-up.

I should add that there are some sleep-wake issues if you leave the display connected to the Mac and put it to sleep. Also, I noticed a yellow tinge on mine and am awaiting a replacement.

I sleep/wake my laptop a dozen times a day and have never had an issue with the monitor.

If this was driver related I'd think everyone would have this issue.

Could Apple be loading different drivers for different system configurations?

If there is no chance different laptop models could get different drivers then this would have to be a hardware issue on either the laptop or monitor.

I've been having a lot of random crashes requiring reboots with my 15" and the display.

Anyone else had similar?

Can you try booting to safe mode and see if the crashes continue? If they don't it's likely being caused by a 3rd party app, extension, etc. Not having crashes in safe mode may help narrow down the cause.

Someone in another thread mentioned the OSX beta may have a fix for this. Curious why only some are affected. Hopefully the majority of issues can be fixed with software as many people are likely past their 2 week return period.

How do I get safe mode?

Tempted to go back to Apple and swap it for the maxed out version now as the fans ALWAYS kick in majorly.

More so than on the 13" - it just doesn't have graphical glictches. It just crashes instead! Lol
