I got this monitor today and I have to say that it is really nice (also did a great job of adding to my setup). It worked without any problems, the HDR works well and the picture is fantastic on it. The only downside is that I have a little light bleed on the left side of the screen (picture included, nothing that would deter me from using it or cause me irritation I just thought it was worth mentioning (but I will update if it gets worse or other issues arise). Other than that no issues, not a dead pixel or anything else.! Update 1: The light bleed was gone the next day and I haven't seen it since. A little strange but I am not complaining.!! Update 2: The light bleed I had when I first go the monitor (you can see the picture included) is completely gone and I have not seen it after the 2nd day of use, so give it a couple days to make sure it doesn't just disappear.I got this monitor because I do a lot of 3d modeling and photoshop work. So far I have done some drawings in photoshop and not a single complaint. I will update my review as I use it more.! Update 1: I decided to give gaming a try with this monitor and while it is the first 4k monitor that I have owned. It was fantastic, I even got to use the HDR in THPS1 and it took the visuals to another level. But I will say if you find games with HDR capability, at least with the one I tested it took some fiddling with the settings to get it looking right.!! Update 2: The gaming performance is amazing, HDR gaming is spot on and the detail is generally unreal (I only used a 2k monitor for about 6 months before getting this and prior to that I was using 1080p. So leaps and bounds better. As for modeling with Maya, it works amazingly (a little laggy, I think doing all that work on much more pixels takes more work from my pc, but it isn't anything horrible. Just keep in mind to keep off any "effects" (ambient occlusion, motion blur, etc.) if you are animating to make sure that it plays smoothly, unless you have an epic system.Pros:- Great screen- HDR works well- Not a single dead picture- Beautiful 4k gaming and HDR support for games that offer it.-Beautiful for animating in Maya.-Beautiful for working on drawing in PhotoshopCons:- A small amount of light bleed off of the bezel ***Gone after a day or 2***Unknowns:- Color Accuracy (I am planning on trying color correcting in a couple months when I get a calibrator to get an idea of how close everything is.)

I had a lot of anxiety over whether the resolution of this monitor is on par with iMac 27 5K or LG 5K monitor. Had worked with both monitors and played around at Apple Store with both. Always amazed at the resolution and clarity of both LG 5K and iMac 27.From a photographer and pixel peeper standpoint (and owner of LG OLED TV, iPhone X owner): this 27 inch LG is on par with both of the above LG 5K and iMac 27 5K for a fraction of the cost.1) Resolution is beyond what is considered "retina" in my book. I cannot even run this monitor on its full 4K resolution as it is just beyond "retina" at that point. It is, for all intents and purposes, as "retina" my iPhone X and MacBook Pro 13 inch with Retina display. I would not even hesitate to consider LG 5K monitor over this monitor as the 5K resolution is completely useless for practical purposes (i.e. content will look so small at 5K in a 27 inch monitor that it is unusable).2) 27uk850 vs 27uk650: the USB-C is absolutely worth the extra 100$ cost. Not only integration with Apple ecosystem is seamless, but also the back of this monitor (and not the 650) has regular USB ports that can be used to hook up your peripherals too. For instance, my wireless mouse (not bluetooth, has a small receiver) is hooked up to the back of the monitor and works seamlessly with the MacBook. This saved from buying a dongle to convert my receiver for the mouse to USB-C and saved me from using a USB-C output on MacBook for connecting a mouse.3) Charging of MacBook via USB-C is also key. Otherwise, I would have been left with absolutely no ports to hook up anything to my MacBook (1 USB-C gone for displays, 1 USB-C gone for charging).850 is absolutely worth the price over 650. Would not even be able to live with 650 now that I see the difference.Please don't worry about whether this is "retina" enough compared to LG 5K at $1300. This is absolutely "retina" enough with excellent color reproduction.Now the whole DCI-P3 business, I'm not sure about. But then again, I'm a photographer and have never felt like I'm lacking "colors" in even my MacBook Pro monitor which is not covering the whole DCI-P3. The additional cost of having DCI-P3 is absolutely ridiculous in 2018 in my opinion and the difference likely very negligible for 97% of users. I could understand if your life depends on accurate color reproduction, but for the rest of us, DCI-P3 is not worth an extra $700.Excellent monitor. Speakers are also a nice addition. Reduces clutter from the desk. And can be turned off. In my opinion, the inclusion of USB-C and the back ports of the monitor to attach other peripherals via regular USB is absolutely worth the extra cost compared to 650, even not including the speakers.

The 4K display on the LG 27UK850-W 27" monitor is flawless. It's worth every penny. I upgraded to this monitor primarily because of the USB-C connectivity. I purchased a new Apple 13" MacBook Pro (2018) which has four USB-C ports as it's only way to charge and connect peripheral devices. I was skeptical that a single USB-C connection could provide data and power, but I am a true believer now. Amazingly, I only have ONE single USB-C cable connected from the laptop to the monitor - no tangle of laptop charging cables, wall transformers, or data cables. This makes it so much easier to disconnect the laptop and go mobile, and reconnect when you come home.The LG 27UK850-W 27" power block supplies ample power to the monitor, peripherals, and charging capability to the laptop. The monitor's two USB 3.0 ports are adequate to support my 4-port USB hub. Strangely, the supplied USB-C cable is a must for connecting your laptop - the genuine Apple USB-C cable won't work. The monitor also sleeps/wakes perfectly and causes no radio frequency interference with the bluetooth keyboard and trackpad.The internal speakers are average. I recommend getting a pair of decent powered speakers. I connect a pair of powered speakers to the monitor's audio input and they work perfectly. The sound is passed from the computer through the monitor to the speakers.The LG 27UK850-W 27" is a solid choice if you are considering purchasing a 4K UHD monitor. You won't be disappointed.
