    Will this be a good alternative for the new Macbook Pro 15"?

    Price fairly good around 550 EUR and 27"

    I am about to pick up my 13 inch today and I have the same monitor so we are about to find out shortly, but my 12' MacBook ran the monitor just fine with the USB-C cable so I am certain the 15' MacBook Pro will do just fine.

    Hi Hung_Solo
    Any news? Does it work properly together? I'm specially interested for the following topics, when connecting the monitor with a USB-C cable only:
    - Does it charge the 13" MacBook Pro?
    - Is it possible to have 4K 60Hz (not only 30Hz)
    - I've heard that the USB Ports on the backside of the monitor are only capable to deliver USB 2 speed when connected via USB-C. Is that correct?

    Really interested in your experience, thank you for sharing!

    1) Yes it will charge it
    2) Yes it is 60Hz
    3) Yes, the ports downgrade to USB 2 if you are also using USB-C for your video feed

    Thank you laser71
    Sounds more or less good. USB 2 is a pity but as I saw based on technical limitations. Looking forward to buy the LG 27UD88 ;)

    Any noticeable lag when driving both displays and using things like mission control with lots of windows open?

    1. Works with the 13" MBP (non-touchbar) with no problems.
    2. Monitor displays 4k at 60hz with no issues and it charges the laptop.
    3. I haven't tried transferring any data yet with the ports on the monitor so I cannot confirm.

    Bump: Has anyone used this with the 15" MBP? Does it work?

    I'm using it with a 15 MBP as a secondary display. The picture is fine, full 4K resolution with 60Hz refresh rate. The charging is NOT working, the 60W output simply not enough: the power status is connected, but "Battery not charging". In fact the battery drains constantly, so you will need the original power supply. I can't say anything about the usb speed, i did not tested it yet.

    It sometimes charges my 15".
    Maybe only with very light use? (power from monitor > power used by MacBook?)

    right now, safari, iTunes, mail, calendar etc open, nothing heavy, and its charging my MacBook. its at 28% and says it needs 3:06 hours till full.

    on second thought: It shouldn't really be a problem that the power from the monitor is that low. it should only charge slower. the "Battery is not charging" might be a bug.
    I've seen a video of someone plugging in 4 power adapters. nothing interesting happened but when he went back to 1, it also displayed "Battery not charging", and this was with a normal apple power brick.
    so hoping its just a bug and it will get fixed in the next patch :)

    Got the 2016 15", and this particular monitor.

    As crazy as it sounds, to get it to charge the MacBook you sometimes have to turn the USB-C cable the other way around (yes, I know USB-C is a symmetrical connector blablabla) but I was astonished when I found out online that this was the workaround.
    It's charging my MacBook Pro as I'm writing those lines, sometimes up to 60W (when the battery is low), and right now at 18W cause it's fully charged.

    It definitely charges the MacBook Pro. Really satisfied with it.

    PS: USB 2 Speeds on the USB-A ports of the monitor, I can confirm.

    I've just got one of these models and I don't seem to be able to get it to charge my MacBook Pro 15" and drive the display at the same time. I'm wondering if it's because I've gone for the model with the discrete AMD 455 GPU. The GPU obviously draws more power, so could well tip the balance. It always reports "Battery not charging"

    I can deactivate the GPU and get it to use just the integrated Intel graphics, and in this setup the battery does begin to charge up. However, with this setup the monitor's screen doesn't detect any input. Running this external screen seems to require that the discrete graphics is turned on.

    I've been using this for a few weeks now with my 15" - it will charge the battery if I only have one external monitor running, and no taxing programs running. As soon as I start doing anything more than web browsing, the charging stops and it slowly drains the battery.

    It charges overnight, but I don't foresee being able to rely on the monitor power alone. Bummer.

    The 4k LG UltraFine sold by Apple also has 60w power delivery. Does/will it have the same issue with charging the 15"? The 5k UltraFine pushes up to 85w.

    I would wait for next years model - they're bound to release one with the new MBPs in mind.

    I think I might even prefer a 4K display as I'll also be able to use it with a PS4 pro etc.

    We will see what companies come out with at CES in about a month. Hopefully we will see some additional options for Type-C/TB3 displays that don't require us to question compatibility and performance. I am a little apprehensive to order a new display at this point.

    Same - I'd either order the LG5K or wait until next month's CES.

    I'm tempted to order the LG5K anyway... then if something better turns up at CES, cancel it :D

    You tried plugging it on/off multiple times and rotating the USB-C cable as I said?

    Mine is charging no problem when turning the cable the other way around. Goes from 0.5W to 56W. 56W will be enough for everything, as power hungry as it may be.

    This actually worked! I had the same issue. 15" MacBook Pro 2016 with the AMD graphics and it was showing as been connected to power but not charging. I reversed the Usb-C cable that came with it and it is now charging the MacBook Pro. I am doing nothing that is very processor heavy (email, web browsing and iTunes) but its working just fine.

    I haven't tried the cable reversing trick.. (though I will, the next time I get 'not charging'). My trick usually involves simply, unplugging and plugging the USB-C cable a few times until the charging starts. I know that you need to wait what seems like 30 seconds for the cable negotiation to start. Another note to point out, when I use the apple supplied USB-C cable in the monitor, it powers every time, but a video feed doesn't register.

    That being said, 57W seems to be enough to keep the battery charging even with all the apps that I have open (Xcode, Sketch, Safari, Slack, Spotify, iTunes, source tree).

    Regarding the Apple Câble, it's perfectly normal as it is only a USB 2.0 cable.

    So the ports are only 2.0 after the lanes are used for 4k video ?
