MacBook 12” (2016)
You can buy 2,3, or 4 and use them in tandem. They do not daisy chain though.
The LG 4K display does not have a DisplayPort output to support daisy chaining.
The LG 4K is a USB-C display (USB-C with DisplayPort alt mode, using DisplayPort 1.2 (4 lanes), and USB 2.0).
I don't know if macOS supports DisplayPort MST (for daisy chaining displays using DisplayPort). The MacBook Pro supports DisplayPort 1.2 which can't support more than one 4K 60 Hz display anyway.
Each side of the MacBook Pro (left side and right side) can support two displays. The MacBook Pro 15 inch allows up to four 4K displays. The MacBook Pro 13 inch allows two 4K displays.
Thunderbolt 3 can support two 4K 60 Hz displays from a single port using Thunderbolt display daisy chaining, a Thunderbolt 3 to Dual DisplayPort or HDMI 2.0 adapter, or a Thunderbolt 3 dock. However, I am unaware of any Thunderbolt 3 product that has more than one USB-C port with DisplayPort alt mode (required for USB-C displays like the LG 4K).
It might be possible to use an LG 4K with DisplayPort only (no USB) by using a USB-C to DisplayPort cable, but then any functions of the display that require USB will not be usable (audio, brightness control, USB hub). Brightness control may be possible using an app that uses DDC/CI.
To get two ports supporting USB-C with DisplayPort alt mode from a single Thunderbolt 3 port (so you can use the other 3 ports for other stuff), you need the following:
1) two Sunix UPD2018 or two Delock 89582 (PCIe USB 3.1 gen 2 host controller with USB-C DisplayPort alt mode port).
2) one Thunderbolt 3 PCIe expansion box with two or more slots such as the Sonnet Echo Express SE III, or two Thunderbolt 3 PCIe expansion boxes each with one slot such as the Sonnet Echo Express SEL (Thunderbolt 3 Edition).
3) one Thunderbolt 3 to Dual DisplayPort adapter such as the one made by Sonnet (not all Thunderbolt 3 products are Mac compatible so check the manufacturer's specs).
No, except in Windows 10 (tested in bootcamp). Utterly pathetic, isn't it?
I just bought the LG Ultrafine 4k Display... And a brand new Mac Mini. I can't get them to work. Is it me? Or do they not work together?
I was just in the Apple Store and they now use the LG displays with the Mini and MacPro. I didnt check the adapter and port used.
Short answer: No.
The Apple 4K TV has only an HDMI 2.0 output.
The LG UltraFine 4K display only has a USB-C input. It uses USB-C with DisplayPort alt mode. The USB-C cable has wires for the DisplayPort signal, and wires for a USB 2.0 connection which the LG display uses for brightness control, audio, and its USB ports.
Currently available HDMI 1.4 to DisplayPort adapters only support 4K 30Hz. Next year may see HDMI 2.0 converters that support 4K 60Hz but may cost up to $200.
Other computer monitors have HDMI 2.0 inputs and DisplayPort 1.2 inputs.
The general consensus of people I've talked to recommend against long-term operation of a MacBook Pro with a "less than stock" power supply. That is, people say you can damage a MacBook Pro 15 using the power supply for a MacBook Air, for example.
So can you just plug the USB-C connector from this display into the new MacBook Pro 15 as a single-plug "dock", or do you need to plug in the MacBook Pro's power supply as well?
I use it with a 15" MacBook Pro and it charges fine. The only difference is in the time it takes to charge the MacBook if it's discharged when connecting it. There's no reason at all you can't use the lower wattage without damaging your battery. Exactly the same as you can use lower wattage adapters for iPads for example, it just charges slower.
There aren't any buttons and screen will be black until you put in your usbc cable to the right port from a new MacBook Pro only. May be a MacBook. Remembering it is usb-c protocol not thunderbolt! So no thunderbolt2 to thunderbolt3 USBc option on this either!!
The best method that I have for turning OFF this LG display, and the Apple Thunderbolt/Apple Cinema Displays, is by setting up a "Hot Corner" where you move the mouse into an assigned corner of the monitor to initiate putting the display to sleep.
Go to:
~System Preferences
~Mission Control
~Hot Corners... (Bottom left of Mission Control menu)
...then select the corner that you would like to have as the assigned Hot Corner, open the Drop Down Menu, and select "Put Display to Sleep" and the display will go into Sleep/Standby while still supplying power to your MacBook Pro.
Does this run at 30Hz, 60Hz, etc?
60Hz
Is this Vesa Compliant? Wall mountable? 100x100?
Yes, comes with an optional VESA plate, looks like 100x100 but doesn't say so.
I've got my bluetooth headset and magic mouse plugged into my display in order to charge them. Unfortunately, the USB stops charging when the Macbook is disconnected. So I can't charge these devices when I'm away from my desk with my computer.
Most Definitely.
Hi all, I'm wondering if this display is compatible with the previous generation of Retina MacBook Pros? More specifically, my 15" Mid 2014 Retina MacBook Pro (2.8GHz QC i7, 16GB RAM, 1TB SSD, GT 750M 2GB)? I know this display only has USB-C inputs, but if I bought one of Belkin's USB-A to USB-C cables, would it work? It is from my understanding that USB-C is really just a smaller, reversible version of USB 3.1. Thanks again, -Alex
As far as I can tell, it is not. I have a mid-2015 15" macbook pro with retina display, 2.8 GHz Intel Core i7 processor, 16 gb of ram and Intel Iris Pro 1536 MB graphics card.
I've tried it with TB 3 to TB 2 convertor and an HDMI cable, a USB-C to mini DisplayPort convertor and mini DisplayPort cable, and USB-C to 4k HDMI convertor with HDMI cable / port as well, all with no luck. The mac does connect to an old TV using the HDMI cord, so I don't think it's an issue with the mac. The plan from here is to call LG support and find out if there's ANYTHING I can do that will allow me to use the monitor with the mac. Otherwise, I sure hope they'll take it back at apple, since my company bought it and I've already discarded the box.
I'll update this answer if I find any combination that works.
Actually, Mscbook Pro 2013 seems to support 4K displays with MST only. This display is SST. So, even if Thunderbolt 2 equipped Macs prove to work with this display, you have a bigger obstacle due to your MacBook not supporting 4K SST displays.
You would need an HDMI connection to use the Apple TV 4th Generation. With this Display, it wouldn't support that HDMI connection.
Hey everyone,
I'm wondering if I can drive this monitor from a USB-C-to-DisplayPort Cable.
I am looking at the upcoming Thunderbolt 3 docking stations, and all of the products announced only have 2 Thunderbolt-3 ports on them. Most have either HDMI or Displayport ports as well, though. I'm obsessive about cables/mess, and only want to have one connection running into my 2016 MacBook Pro with Touchbar.
My thinking is that I can use a USB-C-to-DisplayPort cable into the monitor from the dock, as the specs show that the Displayport on the dock can do 4K video.
1st, Will this actually work? I'm assuming it will.
2nd, Will all of the Monitor controls still work? I love how this monitor has all the brightness/color setting controlled through system preferences, and I would want this functionality to work as well.
Has anyone tested either of these things?
For reference, I am looking at the Belkin Thunderbolt 3 Express Dock HD, and the Henge Docks Tethered Dock for MacBook Pro 2016 (Thunderbolt 3).
Thanks all,
James
I just went through the same thing - and ended up returning the Belkin TB3 Express Dock. I have put my gigabit ethernet adapter and backup hard drive into the USBC ports on the monitor, and then one USB-C from the monitor into my MacBook Pro with Touchbar. I don't think it is quite as fast a network connection as I get when I plug the ethernet adapter directly into the McBP - but nice to have just one cable to disconnect and go.
I originally bought the Belkin TB3 dock to enable use of a lower cost 4k monitor - but then lots of reviews on problems with reawake after sleep, disconnect/reconnect cables to refresh display, etc. Decided to put the $350 from the belkin towards the nicer LG display and let it to the USB-C hubbing for me. Seems to be working out ok.
