    A single USB-C cable (included) provides up to 60W of charging power to your MacBook with USB-C port or MacBook Pro with Thunderbolt 3 (USB-C) ports. And three downstream USB-C ports (480 Mbps) offer additional connectivity and power to compatible devices and accessories.

    Built-in stereo speakers deliver an enhanced audio experience. And with over 9.4 million pixels, your text, photos and web pages will look sharper and more vivid than ever.

    A perfect complement to your MacBook or MacBook Pro, the UltraFine 4K Display gives you plenty of room for a multitude of tools and windows, while rendering incredibly lifelike images and razor-sharp text instantaneously.

    Simplified user experience

    Connect the UltraFine 4K Display to your MacBook or MacBook Pro via an included USB-C cable, which supports 4K video, audio and data simultaneously — all while supplying up to 60W of charging power to your MacBook or MacBook Pro. And with seamless macOS integration, you can control volume and brightness on your 4K display without the need for physical buttons.

    Use the adjustable stand to create a personalised environment for work or play. Or disconnect the stand and mount the display on your preferred VESA arm using the provided VESA cover.

      Great screen and build quality, but screen blanks out every few seconds

      The whole screen goes black for about a second every 8-12 seconds - not triggered by anything like keyboard input or trackpad. Problem is solved temporarily by The whole screen goes black for about a second every 8-12 seconds - not triggered by anything like keyboard input or trackpad. Problem is solved temporarily by rebooting with LG display plugged into MacBook 2016, until MacBook goes to sleep or you unplug and replug when problem restarts.

      Terrible product - Avoid

      This Monitor will black out every 10 seconds. Having spoken to both Apple support and LG support they both have yet to receive any information on this product. This Monitor will black out every 10 seconds. Having spoken to both Apple support and LG support they both have yet to receive any information on this product. LG's advice was just to return it to apple as they have never seen one and none of there support use Apple products. Apples advice was you have 14days to return it. This is the first time I have ordered a product via Apple's website and felt let down by it. Save your time and money and avoid this until they solve the issue.

In my opinion the iss This issue also occurs with my Philips USB-c connected screen and with some monitors/projectors when using apple's USB-c display adaptors. In my opinion the issue relates to the display port over USB-c implementation rather than the screens. It still requires Apple to fix the issue though given increasing number of new USB-C based MacBook Pro users

      Love it, great for connecting to mbp

      I use this with my 2018 quad 13" MBP. It works perfectly.

I use it in clamshell mode, when i get to the office I just connect it via the USB-c cable and it charges my MBP and shows an awesome picture. The image quality is very good. As good at least as my old 2017 iMac. No heating issues using this in 4k mode with my 13". The only complaint is that the built-in speakers aren't great. Also, the USB-c are only USB 2 speed. I guess I'd also have liked a headphone socket but oh well. This plus the top 13" works far better for me than a 15" at the same price. Very happy.

      An absolutely stunning display

Perhaps I'm lucky but, for me, it's been an absolute I wanted a screen for my MacBook Pro and bought this with some trepidation due to several negative reviews. Perhaps I'm lucky but, for me, it's been an absolute dream and perhaps one of the best pieces of computer equipment I've ever bought. • Unbox monitor • Plug it in • Connect the supplied USB-C cable to the MacBook Pro • Hey presto! Monitor comes to life with the most amazing image quality. Not only that, it charges the laptop as well. Unplug the laptop and the monitor automatically turns off. Love that, too. One thing to bear in mind is that the audio output automatically switched from the MacBook Pro to the monitor (at full volume) so that shocked me when an e-mail came in. Simple to change that in System Prefs of course. But really, it's a stunning piece of kit. Very solidly built and really, the picture is just amazing.

It works seamlessly with the latest MacBook Pro (so much so that I've ditched my ageing desktop Mac completely). Negatives: It's small. I wish that I had saved enough for the 27" model. Whilst the solidity of the stand is excellent and it adjust vertically and tilts with ease, the lack of any swivel means that I have to lift the hefty base plate to move it (we don't all sit locked into a single seating position). Finally, and really annoyingly, I have a dead pixel which I only discovered when trying to edit it out of a photo! It's probably not enough to battle over a belated return, but do make sure that you set the background to plain white to test it when you get one as desktop backgrounds can easily mask these imperfections.
