May I know which Aukey USB-C hub you are using? I can only find one that support 3440x1440@30Hz
Got a tip for us?

Did that hub support charging the macbook and 4k@60hz video output at the same time?
There are two models

and

I have the first, and while it states 4k @ 30Hz, its been rock solid for me at 2440x1440 @ 60Hz over the past 6+ weeks. There are some mixed reviews, YMMV.

In case anyone else runs into this, to enable 60Hz after the application of the patch in clamshell mode, you option select the resolution options and you'll then have the ability to switch from 30Hz to 60Hz (previously mine was switching to 30hz if the lid was closed)..
Also, I haven't had to repeat these steps when reconnecting the display.

Yes. Nicely enough I didn't have to reapply it after installing the first or second beta.
[doublepost=1469043457][/doublepost]I think the only documented downside is that the bandwidth required for 60Hz drops the USB devices down to 2.0 speed.
Yes, if the monitor has a USB C port and you have the right USB C cable attached. The LG 27UD88-W can do it.

Neither of the videos you showed mention clamshell mode.
Also, the video showing 4k@60hz output does not mention whether he still gets power.
So, I am aware clearly that 4k@60hz is possible. What I am not aware of, and and still not aware of after reviewing the videos and other posts in this thread, is whether you can do 4k@60hz while charging the Macbook with the Macbook lid closed and in clamshell mode.

Why would you need the patch? rMB should have no problems running this out of the box at 3440x1440 @ 60Hz.
30 or 50 Hz are the only available choices
Currently running at 2560 x 1080 @ 60 Hz. Text is fuzzy. Better than the flicker. Oh man, that's awful.
That's odd cause others have reported no issues running these wide monitors at 3440x1440. Maybe you need an upgraded HDMI cable.
What sort of adaptor could provide charging and 4k@60hz output?. At home, I have a USB-c monitor but at work I connect to a 4k monitor with a USB-c splitter which gives me a regular USB and HDMI + charging.
I prefer 1080p hidpi at 60hz which I can´t from HDMI 2.0

This might be a stupid question, but can MacBook + LG 27UD88-W monitor do (in 60hz with patch) scaled resolution "looks like 2560+1440" as shown in the picture?

You can do it with Quickres but text looks fuzzy. I would only plan to run high DPI 1080P or true 4K on the LG monitor (I have the same one.) 4K obviously makes the text look tiny but 4K video looks amazing.
Thanks for the reply. It does work flawlessly through USB-C? Have you noticed any hiccups or anything with the UI, apps etc when using that setup? Could you confirm that it works lid closed and is charging all the time when USB-C is connected to monitor?
I am considering of bying that setup. Best of both worlds.
If you apply the patch to do 4k@60Hz the only hiccup I've had is that I have to reboot sometimes to get the 4K option if I disconnect the laptop from the monitor and reconnect. Yes, it is always charging if the monitor is powered on. I only had the monitor for a week before I left for vacation so I haven't tried it with the lid closed. I hear it works fine though. I think that's only an issue with Macbooks that run separate cables for power and display output.
Just got this setup myself. I would not say it works flawlessly, but it does a pretty good job. I did apply the patch myself and noticed that while at 1080p HiDPI that when I watch video it stutters a bit that is noticeable. When I switch it back to 30hz the stuttering is non-exinsistant.
My MacBook has also gotten pretty damn hot at around 36 degrees celsius while watching video websites like YouTube.
This is only from my own personal experience though.
