    I just moved from a retina iMac to a Mac Studio and was looking for a monitor that was as good as the retina in the iMac. First off, nothing is as good as the retina iMac screen except the new $1,500 Apple monitor. But, this LG gets you 99% of the way there. It takes a little fiddling to get the resolution right but after working with it a couple of weeks, I cant tell the difference between this monitor and the iMac when writing code - working with text. No idea about games or professional graphics. As far as casual watching YouTube and web browsing its every bit as good as the retina iMacs. I liked it so much, I got a 2nd one to connect to the Mac Studio replacing an older 27 Apple Thunderbolt display. The monitor works great out of the box with the included USB-C cable. I now have 2 connected via the USB-C cables and they are great. Probably the only downside is the built in speaker. Its no where near what the iMacs speakers sound like. To solve that one, I found a Nylavee sound bar and it fits snugly under the monitor. One other issue I have not solved yet and it could be self inflicted is the computer sometimes will not go to sleep from the sleep menu the first try. Another issue is open apps dont always stay on the 2nd monitor when the computer wakes up. This is a known problem when using non Apple displays so it might have to be something to live with until Apple has time to stop making new emojis and fix a few bugs in their software. Now Im back to what I had with the iMac, except now I have 10 cores and blazing speed.

    I researched several monitors to pair with my new M2 Mac Mini and chose this one. Very happy with it just as it came out of the box. Disclosure: Ive not tried tweaking the picture at all. There is a comprehensive manual that I have merely glanced at. Just out of the box this is simply great.

    So far I am loving this monitor, for the price this is an excellent display. The 27inch size is perfect for me. Plenty of screen real estate to get work done, the 4K resolution helps as well. Especially when you scale the resolution for more space. The colors in my opinion are very accurate, I can definitely notice some differences from my P3 calibrated MacBook Pro but it very close. I do some minor photo editing and the experience has been great so far. The matte display is also very nice. I’ve used previous monitors with matte displays and this one is noticeably high quality. You don’t see that typical grainy texture that often comes with matte displays. USB-C connectivity is extremely useful, it’s very nice to use one cable for display and power. I have experienced a few times where I noticed the MacBook was not charging but it only happens occasionally. My only complaint is the stand is a little cheap feeling, I wish the whole thing was metal and a little my sturdy. The HDR performance is pretty terrible, I don’t recommend it. When you enable HDR it looks noticeably worse. But the standard display settings out of the box are adequate for most. I would say this monitor is excellent and I would highly recommend it if your looking for a midrange 4K monitor.

    I have had this monitor for 2 years, love it for using a laptop and working on a larger screen. The USB-C to USB-C cable needs replacing, sometimes it works and powers the computer and sometimes it does not power? It connects to the monitor for a picture but not power? I cannot find the appropriate cable to replace? If I plug in a USBC- to USB-C it does not connect to a picture?

    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.

    Running this on a Macbook Air 2018. Its great, once its configured at a proper resolution -- almost as good a screen as the Airs own Retina. Has a matte finish, but thats no issue to me. Displays text and graphics quite sharply. The only drawback is that I also tested it with a 2014 Mac Mini, and for that there is simply no adequate resolution that looks good, even via the utility SwitchResX which is my go-to in such cases. But with modern hardware I wouldnt think anybody would have cause for complaint, and I certainly like both the USB-C cable for delivering power to my laptop and the extra ports on the back, including two USB-3 ports I use for things like external drives. Highly recced. You wont likely be sorry.

    I bought this as a used-like new monitor for $380. It was in fine condition but had over 230hrs of total power on time and was missing a few cables and pieces. Amazon customer support helped replace what I needed. Buyer beware... Picture quality is good, not great. With a plain black screen up you can see uneven backlighting in the corners. Also, its a matte screen, so everything is a little fuzzy and the blacks are not as deep as a glossy screen, but some people might prefer it (I guess I missed the memo that glossy screens are no longer in vogue). Brightness is a pain to change! It takes 5 clicks on the LG joystick to navigate to the brightness setting and change it 1%. I think thats probably too fine of an adjustment. Maybe take a page from Apple and have brightness go from 0 to 16 instead of 0 to 100. Im using this with a 2017 macbook pro via HDMI.

    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 purchased a second monitor, as I moved the first to my new iMac. After several months, I am very please with the first monitor. I will post the same review below for the second monitor, as it now is attached to my MacBook Pro. This monitor is great for the price. I easily assembled the stand, plugged in the USB-C cable, and it was up and running on my 2016 MacBook Pro. The picture was fine out of the box, though way too bright for my dark studio. The colors are a little off with the auto-setting compared to the MacBook, so I will need to adjust them a bit. If anything the screen is a little too large, but I wanted the real estate to post-process photos. This was a very good purchase.

    Update 8/16/2021: one display has developed two vertical lines of dead pixels after less than a week of use. This was a Warehouse returns, so the fault lies more with Amazon than LG. I purchased a pair of these 27UN850-W displays, and they perform as you would expect from a mid-range IPS display, good color accuracy, wide viewing angle, and no dead pixels on either. For productivity work, these are perfect. 60hz refresh rate isnt going to cut it for high-end gaming although Freesync will help there. Color accuracy isnt going to be sufficient for professional design and video editing. Certified for HDR400, but know that this definitely HDR-light, if you HDR is important to you, look elsewhere. Didnt try the monitor stand, but VESA mounting worked as it should. Left, right, and top margins are about 1/4 so for multi-monitor setups you will have about 1/2 boundary between workspaces. For dual monitor work scenario for documents, GIS, code, and the like, flat panels with a wide viewing angle like these are quite good. For me, these were an excellent value from Amazon Warehouse (Used - Acceptable), where these like-new displays that are missing bonus materials cost under $300. At MSRP of $450, these are a fair price.

Upgrade to an LG UltraFine IPS 4K screen, delivering ultra HD resolution with supremely accurate colors, even when viewed off-angle. The 27-inch display offers versatility of USB Type C connectivity (60 Watt power delivery) plus the benefits of HDCP 2.2 compatibility, so it will seamlessly display 4K content from a variety of sources. Experience smooth gameplay with AMD FreeSync (used with supported video cards), virtually eliminating screen tearing and stuttering that occur as a result of the difference between a graphics card"s frame rate and monitor"s refresh rate. Dynamic Action Sync reduces input lag and elevates your gameplay, allowing you to respond to your opponents quickly. Keep visibility even in dark scenes—LG"s Black Stabilizer senses dark scenes and helps make it brighter so that you can find the enemies hiding and waiting to attack your player in the dark. *Software download required to enable OnScreen Control.
