      Problems connecting two LG Ultrafines with new 15 inch MacBook Pro

      Connecting two of these LG Ultrafines with a new MacBook Pro 15 inch, there are a few major problems: 1) the MacBook will not charge when the two monitors are Connecting two of these LG Ultrafines with a new MacBook Pro 15 inch, there are a few major problems: 1) the MacBook will not charge when the two monitors are connected - it only charges after unplugging and replugging in the monitors a few times 2) only one of the monitors wakes up when the MacBook wakes from sleep - only by unplugging and replugging does the second monitor reconnect. It also appears that the MacBook will not charge via the Thunder bolt cable if the USB-C hub is being used for other peripherals (e.g., charging my iPhone). Considering that Apple unveiled the new MacBook Pro, showcasing a setup with two external LG Ultrafines, it's pretty disappointing that these basic functions don't work seamlessly. When you also consider there very high price for these items, it's not really acceptable. The monitors are beautiful (when they are working) - but I'm waiting to see if Apple fixes these issues fast - otherwise the monitors get returned. Apple Support don't know anything about the problem because it's too new.

      Absolutely stunning display quality at a great price - but ONLY USB-C

      First of all, this is quite possibly the best 4K display I have seen in terms of color accuracy and detail. The display finish is similar to Apple's latest MacB First of all, this is quite possibly the best 4K display I have seen in terms of color accuracy and detail. The display finish is similar to Apple's latest MacBook Pros - clear, glossy but very little reflectance - the best of both worlds. Connected to my 2016 MacBook Pro with its native USB-C connector, the display is stunning. Another surprise? The built-in speakers on this monitor are amazingly clear, loud, and good quality, unlike most monitors. You can even feel the bass (to some extent - don't expect miracles). Now for the downside for all who had *hoped* they could connect this to older Macs with adapters. You can't. The specifications are very clear - this monitor requires a Mac with a native USB-C connector. Apple's Thunderbolt 3 to Thunderbolt 2 adapter doesn't provide DisplayPort pass through. And third party USB-C to DisplayPort 1.2 connectors don't handle the 4096x2304 resolution of this monitor. The monitor is simply not recognized by older Macs.

Internal display speakers sound ok but aren't great. Display looks awesome (zero stuck pixels and no other visible flaws I can see).

      Not user friendly

      Won't work with 2013 Mac Pro (even though the "genius" told me it would). When using it on my 2016 MacBook, brightness buttons don't do anything. The ports Won't work with 2013 Mac Pro (even though the "genius" told me it would). When using it on my 2016 MacBook, brightness buttons don't do anything. The ports on the back don't do anything, maybe they require thunderbolt 3? I guess there are no internal speakers? This display quality looks OK but otherwise, too many things don't work and Apple doesn't do a good job explaining before purchase. This monitor is TOO expensive considering its many flaws.

      Amazing monitor.

      + Amazing panel. + 500 Nits peak brightness. + Software controlled through MacOS + USB-C built in hub + Excellent Speakers + Adjustable stand. + Excellen + Amazing panel. + 500 Nits peak brightness. + Software controlled through MacOS + USB-C built in hub + Excellent Speakers + Adjustable stand. + Excellent Build quality + Powers your 13" MBP. + 1 Single USBC cable to power everything. With all those mentioned, if you went out and purchased a separate monitor and all those others (Speakers, power adapter, usb-c hub) you will end up paying close to any other traditional monitor and missing out on the fantastic hardware/software colab by LG and Apple. I picked this up 3rd party at a refurbished price and it was an AMAZING deal.
