I use a program called Clickmonitor DDC ( https://clickmonitorddc.bplaced.net ) to control the brightness of the LG Ultrafien 4k 24 in Windows 10

LG UltraFine 4K and 5K: Yes you can connect it to Windows computers via DP!!!

Are you connecting another computer to the monitor? While there are two thunderbolt 3 ports, you can't have two computers plugged into it at the same time.
Hello! The hub is not powered by anything in my case and I'm using it with a Lenovo T460s. Maybe in some situation it is required? You'll find out soon

Ooo amazing! I will add that to my post. Does the USB port on the Wacom need to be plugged for the app to work or does the DP connection alone is enough? Can you try it?
The HDMI port of the Wacom Link Plus is HDMI 1.4 (4K 30Hz) and wasn't reliable for me.
There are many cheap HDMI 1.4 to DisplayPort 1.2 adapters that you could use instead.
Club 3d has a new HDMI 2.0 to DisplayPort 1.2 adapter which I think is much cheaper than the ones from SIIG or Gofanco.

Thanks for the reply. So with this, you'd go:

Thank you! Just to clarify, with this be the setup?
PS4 HDMI --> Club 3d HDMI 2.0 to DisplayPort 1.2 -->Wacom Link Plus --> LG Ultrafine
Is that right?
Yes, if you are having no luck with the HDMI input of the Wacom Link Plus, then the mini DisplayPort input is your only other option. I have not tested this.
Thanks for your reply! I am not connecting another computer, but I was powering the Wacom adaptor. Do you suggest to try without powering it and see if something change?
Best,
P.
I managed to get 4k output with no power cable or micro usb. If that doesn't work then maybe its how Windows recognized the monitor, you probably will need to fiddle with the display settings in Windows.
So my order for a Wacom Link Plus was cancelled as item is out of stock. I've been able to pick up a Wacom Link (that has DP and USB with no HDMI). I hope it will work. My LG arrives tomorrow.
I am searching online. I already had one order cancelled because the item was out of stock and they didn't know when they would next have one available. Amazon is out of stock until mid/late June and have jacked the price up to over £100.
Yeah I think lots of people are using it for the UltraFine because before I posted there was a lot of stock then a few days after it started going sold out
Wouldn't it be nice if they'd simply make the LG UF 4k/5k with some additional, more normal, ways to optionally connect?
This is so maddening
This is so maddening
Yes, but then it wouldn't put pressure on others to move on to this simpler technology.
At face value it seems like everything on this monitor is proprietary and made to work only with Mac, but after investigating, it's PC OEMs dragging their feet.
- For example, DP over USB-C is not new. Any computer that supports the latest standards should be able to drive the LG UltraFine without issues.
- Regarding the lack of physical buttons on the UltraFine for brightness, contrast controls etc: the display actually use a standard that has been there forever: DDC. That standard allows the control of those settings on a monitor without the need of physical buttons, and using the display link (DP for example). It doesn't need USB or drivers. But then again, Windows doesn't fully support it natively.
I'm not really sure that pressure is working honestly (or will work).
The majority of the PC space is just fine (more than fine) with 4k options, particularly with how much gaming drives the bus on hardware designs and sales numbers these days.
And when going above 4k, it really is not an issue to just run dual DP cables, particularly if it's a desktop PC build.
The LG UF's are so so limited.
Can you even plug in a 2nd source and do PIP with an HDMI console or chromecast or anything?
It just feels almost punitively restrictive more so than an enlightened choice with more aspirational motives.
My hope I guess would be that perhaps motherboards will come along on the PC side with things like Titan-Ridge capability built in (no add-on card needed), or I suppose if GPU's started integrating what were needed for single cable TB3 to monitors, at least optionally.
I'm just not sure PC centric vendors see enough upside to doing any of these things if it isn't for laptops where docking with one of these HiDpi displays is the goal.
People also thought removing the SuperDrive from Mac was silly and that it wouldn't help the industry to move past it. Same for Apple's refusal to include Adobe Flash on iOS.
We all know what happened with both of those things.
Yet lots of people are looking into the Wacom workaround rather than just buy another monitor. Interesting, no?
If only most PCs did have dual DP or even support for driving a single monitor over 2 DPs. The proportion of people building their own PCs is... Low.
Limited in terms of port, sure. But then again, the clientele targeted is not those with computers that have only VGA ports.
If that's what you want to do with your display, then you're not the target for sure. I don't think that's how most people use their monitors anyway ¯\_(ツ)_/¯
Maybe, but few PCs have two DP. It might be common in the gamer world, but most computers do not.
To drive two 5k displays in your set up, you would need four DP, four cables while with the UltraFine you only need two USB-C ports and cables.
Everything has drawbacks and benefits ¯\_(ツ)_/¯
Hi, i tried to connect my Computer to the LG Ultrafine 4k like this:
Asus GTX 1060 (with DP 1.4) -> DisplayPort to mini DP cable (https://www.amazon.de/dp/B00YOQYQWY/) -> wacom link plus -> thunderbolt 3 cable (that came with the Monitor) -> LG Ultrafine 4k
I can see that windows recognizes the monitor as "LG UltraFine", but somehow, i cannot activate it. (Sound works)
Neither in windows settings, nor in NVIDIA Control Panel. Both with and without micro USB-cable connected.
I have just ordered this DP<->miniDP cable: https://www.amazon.de/dp/B07JWJKFFR/ (says it supports DP1.2)
Hopefully it'll work then, otherwise i might need further help from you.
Thanks for introducing the wacom anyway!

- Have you tried with the USB-C cable included with the UltraFine? For some reason, the Thunderbolt cable included with the LG UltraFine doesn't double as a USB-C cable (e.g. you can't use it with an iPad Pro). If this works, you might want to order a better quality USB-C cable: for some reason, the one included caused random flickering that went away when I switched to another USB-C cable.
- DisplayPort cables are always bidirectional, so I do not think it's the problem, but it's always worth testing.
- When you say you cannot activate it, do you mean that it shows up in the display settings (where you can set resolution and all) but it doesn't turn on? If so, have you tried changing the resolution?
