LG UltraFine UHD 27-Inch 4K UHD 2160p Computer Monitor 27UN850-W, IPS with VESA DisplayHDR 400, AMD FreeSync, and USB-C, White

I’ve had this monitor a few weeks. I noticed the disc it came with was not in a sleeve, just loosely thrown in there. It made me think perhaps this was a return, but I can’t be sure because the rest of the items looked to be packaged correctly… I was frustrated at first because the provided USB-C cable didn’t work with my M1 MacBook Pro. I thought I had received a dud. Looked up some troubleshooting options and nothing was working. I packed it up to return. The day I was going to send it back I decided to check online again for any options. I saw a reddit post from that morning where someone said they had to get a new Thunderbolt 3 cable for the monitor to successfully recognize their M1 Mac. I ran to the store to get one and voila! It worked. The cable was $40 which adds to the cost of this thing, but it’s much cheaper than the 5k option (for the 27inch monitor) they sell at the Apple Store. Overall, I’m really happy with it for the price. I love the single-cable life—no dongles needed since my accessories connect to the monitor itself—making switching laptops from work to personal at my desk easy (with a good double laptop holder). I also think it does a good job of waking in sync with the laptop when I press on the keyboard or move the mouse.

My negative review is only concerns Mac connectivity. The USB-C connection only powered my two Macbooks but the monitor itself was not detected by MacOS at all.

We have an office full of LG 32UN880-B monitors, which were out of stock, so we ordered this one for about the same price. Side by side, this monitor has terrible viewing angles and is far more washed out than our other LG displays. Very disappointed in the quality of this monitor vs other LG HDR monitors.

DCI-P3 98% coverage, brain dead color calibration, 4k, 32in, and the blacks are similar to my va monitors. Checks all the boxes off my list. The refresh rate could be higher but that doesnt matter for my work so this is a 5 stars from me. Nice value from what I can tell.

Great color and clarity. Connects quickly and easily with my M1 Max Macbook Pro. I knocked off one star because the included USB C cable is pretty short and the monitor doesnt work with anything but the included cables. I tried 2 different USB C cables from Apple and a generic one and neither worked. I called LG and they said they dont make a longer one and that is the only one that works with the monitor. I use 2 of these monitors with my laptop so a longer cable would make it much more convenient to connect the one thats furthest away from the computer.

Bought this for my M1 Mac Mini and it works perfectly and looks great. I dont game, so no rating. Ive come to like the control button on the bottom of the display. Easy to find while being invisible. Be advised it comes with both USB-C and HDMI cables, I ordered cables with the product and didnt need them. Started by using the USB-C connection but ended up using HDMI as the M1 Mini (original) only has 2 USB-C ports and then the HDMI port would be unused. Switched using HDMI which also bring out audio. Works great either way. At full resolution, working with multiple documents is painless. Youll need goos vision though! Why Apple calls this display mode more space rather than label with the resolution, I have no clue.

I ordered this monitor hoping to save some space and money over going the route of a traditional 4K monitor and a USB-C/Thunderbolt docking station for my macbook. I was hoping to be able to use one cable for video, data and charging. It works, most of the time, but the USB-C features on this monitor have some frustrating issues. The monitor has issues charging my macbook, sometimes dropping the charge current to less than 10 watts, or other times stopping it entirely, which can only be resolved by power cycling the monitor. Im not sure what the power rating of the USB-A ports on the back of the monitor is. They work well enough with thumb drives, graphic tablets, keyboard & Mice, other low current items, but trying to charge an iphone from them causes a USB power error message to pop up. The audio output on the monitor is not always detected by my laptop, and often requires disconnecting and reconnecting the USB-C cable to get it to work. The mute and volume keys on the apple keyboard are disabled when using the monitors audio output which is a common problem with many cheaper digital audio interfaces, but is still frustrating when compared to dedicated desktop hubs, or USB-C monitors from Dell or Apple which still allow you to use these keys. I downloaded the software package from LG hoping that it would include drivers to enable these features or improve the reliability of the other USB-C features but it does not change anything. The display itself is gorgeous and I have no problems or complaint with it as just a monitor, but I think the USB-C implementation fails to justify its added cost over the displayport only version of the same monitor. Im making it work but will probably purchase a thunderbolt 3 hub eventually to hopefully handle charging and audio more reliably. I love the image quality of the 4k display but if I were to do it again I would either get the cheaper displayport only version of the monitor and an external hub or look at options from Dell or another manufacturer.

I bought two of these monitors: 1. The first one is to connect to a Chromebook for distance learning (via USB-C) and a Kano (via HDMI) for tinkering with code projects. The monitor works great and charges the Chromebook over the USB-C connection. The audio is adequate and is substantially better than the audio in the Chromebook. 2. The second one is to connect a MacBook Pro (via DisplayPort 1.2) for office productivity and watching 4K HDR content and a Dell Optiplex (via HDMI) for office productivity, gaming, and watching 4K HDR content. These monitors perform flawlessly in my two environments! I enjoy the flexibility of having USB-C, DisplayPort, and two HDMI ports to choose from for my inputs. Having these monitors with the built-in adjustable stands allows us to position everything ergonomically to prevent neck and eye strain. Ill update this review in the future after weve used these monitors for a few more months.

Purchased after reading a multitude of reviews for this model and the prior year versions of the same monitor. Went with this newest version. Out of the box connected to a 2020 13” MacBook Pro via the pass through USB-C. One cord- that’s it. I run the Mac on a vertical stand cover closed only using the new monitor as my primary display. No issues with the Mac running with the lid closed at all. Mac immediately charged fast over the included USB-C cord which was a big selling point for me- video and pass-through charging on the included cord. Out of the box the only settings I changed were to increase the brightness to full, increase the sharpness to full, enable the “Super Resolution”, and dial back the audio volume to 20. Unlike a lot of reviews, I found the adjustment joystick easy to use and intuitive. Took all of 5 minutes to adjust the settings, adjusted nothing on the Mac at all. Colors just plain pop. Graphics are crystal clear, tack sharp, and amazing. I agree with other reviews I dislike there is no audio control from the Mac keyboard like I’m used to, but it’s easy to get to from the joystick on the bottom of the monitor to adjust if needed. Audio sounds quite good for a monitor, can’t complain much about the quality. Music sounded just fine. I purchased to use for photo editing, not video, so audio is secondary to me anyway. Very large power brick, plastic construction minus the stand- which is sturdier than it appears. Tilt adjustment, height adjustment, very nice! Virtually no bezel- awesome. Very happy- great pairing to the MacBook. My previous computer was a 2011 27” iMac, and this screen blows that screen away- obviously technology has improved. Would purchase again for sure.

I bought this monitor for how versatile it would be in my setup. However, the main use is with my ps5. I had no desire to get an hdmi 2.1 4k tv as my display, so i settled for a 60hz 4k monitor. This one fit exactly what i was looking for. The 60hz is fine for the games i play, but maybe not for you. I hear hdmi 2.1 monitors will be released this year, so maybe wait on that if 60hz isnt enough for you. Now for the review. I am very picky about my visual and audio experience and this monitor lived up to my expectations. Out of the box, i really didnt like how the colors, brightness and sharpness looked. it just didnt have the pop of the LG 34gn850 despite being 4k and the 34gn850 being 1440p. Once i adjusted what i could with HDR on, i was a bit more satisfied, but still unimpressed. I then turned HDR off and everything changed. I messed with my settings and used the super resolution on high and that changed my whole perception. I was then very impressed. HDR just ruined the colors on ps5. They just didnt pop. The HDR is useless in my opinion and i wouldnt recommend using it. Super resolution has gotten a lot of hate from the reviews i read and maybe it is bad when used as a regular monitor, but as a gaming monitor, this option on high was perfect for me. I think it is worth getting the newer version that has the feature than an older monitor like the ul and uk if you are using it for gaming. Super resolution gets a 10/10 as a feature from me. The black levels are the main issue here. The blacks are almost grey no matter what settings you try. This doesnt bother me at all and is an issue with the 34gn850 as well. I think its just an ips monitor thing. I used an hp2511x tn panel before this and it had way better black levels, but also had way worse viewing angles. I guess its all up to preference when it comes to tn/ips/va but i think ips is still the best. The color accuracy and pop of the colors make ips the winner for me. The response time is fine. I havent done any technical analysis of it, but it doesnt feel any different than the tn panel i was using which was also 5ms. Just make sure you set freesync to extended and response time to faster in the settings. This monitor is great if you go through all the settings and tweak it to your liking. Colors stand out, super res is great. response time is good and the 4k is obviously the main selling point. The negatives are not enough to give it less than 5 stars for me, but i could see people having issues with black levels.
