      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).

      I bought two, two failed. Now Broken again! (See August 4 review)

      I bought two of these, and with 3-4 months, both failed! They were repaired in August. Now one broke again. (Won't turn on.) This is not isolated. Apple I bought two of these, and with 3-4 months, both failed! They were repaired in August. Now one broke again. (Won't turn on.) This is not isolated. Apple really stunk it up going with these LG's. They still produce iMacs, why not keep going with the Cinema Displays?

      Hands down the best

      UltraFine 4K is hands down the best 4K monitor I've seen - And especially a unbelievable steal if you snatched on several $199 refurbished sale on third party s UltraFine 4K is hands down the best 4K monitor I've seen - And especially a unbelievable steal if you snatched on several $199 refurbished sale on third party site (Not Apple). Still come with new box and pristine condition. Only downside is no rotate, non-flexible dock and require you to go all in on USB-C. But then I ditched old MacBook Pro for using a Core M MacBook as my daily driver - That's how good the monitor is, makes enduring Core M worthwhile.

      Very High Quality Monitor

      Finally - a monitor worthy of being paired with a retina device. I tried a few other monitors before landing on this one. I've paired with a MacBook 12 Reti Finally - a monitor worthy of being paired with a retina device. I tried a few other monitors before landing on this one. I've paired with a MacBook 12 Retina and MacBook Pro 13 ... both are fantastic when paired. Daily I run the pro in clamshell mode and enjoy the extra space while having it render text sharp and crisp. I tried a larger 4K monitor and a widescreen monitor previously. While the 27" 4K was clear and crisp, it really was too large for my workflow. It required extra movement on the trackpad. This monitor at 21.5 is "Just Right" and the sound is good too!
