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

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.

This is likely the best monitor that Ive owned. Color, brightness and image definition are excellent. The speakers are oriented away from the user. That is less than ideal. Ful disclosure, I seldom have audio on when operating my desktop. My main gripe is the on/off button. It has dual functionality in that it is also used to access various monitor controls. Not infrequently when I try to power the monitor off, it instead brings up a control menu. A bit annoying. Id prefer two buttons.

UPDATE 11/2022: As long as you take care not to jostle the cord once inserted in the back of the monitor, it works pretty consistently. After plugging the USB-C into the Mac, its important to wait to hear the connected sound, look for the battery icon to show the charging lightning bolt, and only then close the laptop to put it in clamshell mode. If you dont see the charging lightning bolt, the monitor screen will go dark when you close the laptop. __________________________ I purchased this monitor to work with my M1 Macbook in clamshell mode, and that requires the laptop to be powered. The monitor connection is supposed to power the Mac. To be clear: if the MacBook isn’t receiving power when closed, the monitor goes dark. As numerous other reviews have noted, theres something defective about the hub input for USB-C. It works about 50% of the time, no rhyme or reason. Youll hear the connecting tone, then it disconnects, then it connects, then disconnects. From reading other reviews, its no use getting the monitor replaced, because the replacement will have the same problem. I was out of the return period when I realized this was happening. Lesson learned: when you get electronics, use the f&*% out of them right up front, to make sure theyre going to work in the long run. Other downsides: (1) it’s so bright I can only use it at the very lowest brightness level (and I use Flux to dim the screen in lower light); (2) you must manually adjust all settings using a button under the screen. For instance, the brightness buttons on your Mac will not function.

I was looking for a monitor for coding and this LG monitor is just doing its job - text looking crisp and clear, text background is not hurting my eyes and it is just looking like a good monitor.

EDIT: There is On-Screen control for Mac users on newer models its just that LG kind of dropped the ball on making it easy for Mac users to find and install it. On LG.com go to Support, then Software & Drivers. Don’t use the search field they provide because for many model numbers it will say there is no matching product. Scroll down, click on monitors and search for your model manually. If your model doesn’t have a Mac download try the next closest monitor to your model. Also, worth pointing out is that 27UN850-W is the newest model and 27UL850-W is the previous model. They are both practically the same with very minor spec differences but the newest one is currently cheaper by almost $100. ---------- Heads up, their advertised On-Screen Control including Screen Split is not available to MacBook users with this monitor. In fact basically only ONE model is supported! And apparently according to other user reviews that one doesnt even have the basic functionality advertised. So just keep that in mind when purchasing an LG monitor if you are a Mac user. With that said, if that is not a deal breaker for you this is still an excellent monitor.

bought to use with a MacBook Air M1 (2020), crystal clear screen right out of the box, 4K resolution with 60 Hz refresh rate while using the USB-C cable that was included in the box with the monitor (USB-C also charges the Mac while connected). Also includes an HDMI cable. not the cheapest option out there but it looks great and works flawlessly with the Mac Air M1. hopefully the build quality lasts, well see.

Love this monitor! Im a graphic designer and was in search of a match for the macbook pro to upgrade my work from home situation! I had been given several recommendations, read a gazillian reviews and also I could not justify buying the $700 ultrafine mac pairing for a merely 24 screen. Among the recs, on the line comparison from amazon, this showed up and after reading the reviews (which were all great!!) I decided to give it a try. The monitor itself has a nice weight to it, so it does not wabble and is sturdy. I calibrated it with just messing around the tools and settings, and it was calibrated within a couple tries(and I am not super comp savvy). The speakers work great for zoom calls and the knob is easy to navigate - I also purchased the insurance just in case. So far so good! Im super stoked with my decision!

Had it paired with my Mac Studio. Like the color and text, but the back of the monitor looks very cheap. It’s not a pretty white/silver plastic. I end up returning it.

Ok - Ive been working from home for over a year now, so I decided to upgrade my 24 inch BenQ monitor. What a huge improvement - doubled vertical resolution. Makes my job much more enjoyable. Night and day eye comfort. Great investment. No game play; just work. I noticed what others have commented about regarding getting too big a monitor. This one is probably at the upper limit for a work monitor. You occasionally find yourself moving your head around a bit to find things on the screen. With smaller monitors you typically find things via eye movement only. With this size monitor, there is a bit of head movement, not bad, but noticeable - I would not want to go any larger. Again, this is for office / programming work where I have multiple windows open. The adjustable height is a welcome feature. Glare is nicely controlled - no issues. Fonts are very crisp and readable. And the sound is more than adequate for meetings. Others have complained about the joystick control for options selection, but I do not find it a problem whatsoever. Overall - I would highly recommend this for office and programming work.

I am driving this monitor from an MBP 16in. The key aspects are as follows: * The software and manuals are on a CD/DVD. One might wish that at least the packing would include a physical printout of the manual. * Using the USB-C cable to connect USB-C to USB-C does not drive the monitor with all of its possible options available. * Trying to drive the monitor through a modestly-budgeted (Anker) USB-C to HDMI adaptor does not provide all of the possible options and indeed seems to give issues tracking the color calibration. * The only option that worked was to use a trusted USB-C (thunderbolt) to HDMI adaptor (I use one from iVANKY). This drives the monitor with its fullest options exposed in the menu settings. * The menu toggle is conveniently located at the center bottom. You can adjust the sound volume with left-right action. You can select the full menu options with a press. * The speakers are somewhat tinny sounding. When sound is being driven through the HDMI, you cannot control volume form the MBP, you must use the monitor hardware button (as noted above). Now that this is set up, I appreciate the 4k next to the Retina on the MBP (sitting on the right of the monitor). I appreciate the extra screen real-estate. I can have a split-view of two different apps running nicely on this monitor. Finally, I appreciate being able to toggle between different pre-sets in monitor output, such a Vivid, Custom, or Cinema. I use this to run Vivid in daylight, a lower-brightness Custom set in dimmer evening light, and Cinema for video movie streaming. Overall, this is a very good to excellent option as a second monitor to a MBP 16in.
