      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

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).

      Frustration to the max due to missing automatic brightness adjustment

You have to go to the system settings and then Unfortunately, I bought two of those, and it is always frustrating to adjust the brightness if the light changes. You have to go to the system settings and then try to use the slider and move them around to about the same position on each slider. I wish this display would have had buttons and a detached from the macOS functionality to adjust the brightness automatically. It is nearly fraudulent to mention the automatic brightness sensor. For what is it used? Decoration? Those monitors are also somehow ugly. I regret that I bought them and did not send them back in time.

      A great display

Since purchasing it, I' After reading all of the bad reviews, I was nervous about purchasing this display, and nearly chickened out on buying the thing at all. Since purchasing it, I've had nothing but a fantastic experience - literally no problems at all. The image quality is outstanding. I review a lot of documents for my work and PDFs viewed on the display are crisp and bright making reading documents a pleasure. I love the screen of my late-2016 13" MacBook Pro I run this display on, but the 21" screen is a welcomed addition to my work system. No more squinting at small type on documents. I can now see everything. My only regret is that I didn't buy this display sooner.

      Will not recommend

The monitor can only adjust up and down The volume is terrible, the display case rattles when it adjusts above 3-4 bars, even when receiving calls over Facetime or Skype which leads to the next part – it does not have a camera, and overall isn't worth the money. It feels like a $350 monitor.
