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

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.

The screen itself is pretty good in most aspects for the price, except HDR. I tested the monitor with Windows, Mac, PS4, and PS5 in HDR, the colors just do not look right compared to my TV (Sony X900H), no matter how I tune the gamma, contrast, and so on. Peak brightness is okay, but the minimum brightness can be too bright under low light conditions, it is still pretty high compared to the MacBook that I mainly use this screen with. The stand is pretty nice, the screen can be mounted and unmounted quickly, and the screen can be rotated vertically. Although it can only be rotated clockwise by 90°, you cant rotate it counterclockwise, which can be a problem if you had a multi-screen setup and decided to put this monitor closely to the right of another one, the menu joystick at the bottom of the screen would be hard to reach. Speaking of the menu joystick, its not the easiest thing to use, I would prefer a few buttons.

I bought this model LG because this is the model that I read that was used in a lot of Apple iMac models. I wanted a display that had excellent color accuracy since I do photo and video editing. The first one I bought was FANTASTIC! I could see that the colors, contrast, etc. were SPOT ON when comparing to my iMac 27. I give my first monitor 5 stars in all categories! I purchased a second monitor of the same model. I wish I could say the same. The second was HORRIBLE! I made sure the settings were the same on the new monitor as the first one and the picture quality was terrible. I promptly sent the monitor back. Im worried about buying another one and it being just as bad as the second one.

Like a lot of people, I was trying to find the perfect 4k monitor with USB-C capability to have a display for my MacBook Air M1. This monitor is great because not only is the text sharp but it also charges your MacBook. This is easy to use and worked straight out of the box.

I received this monitor and connected to my M1 with ease. It immediately recognized the MacBook. Its mac ready! The colors for Monterey are alike and I didnt see any difference. I am a photographer so this is important. Buy it. Its a great monitor at a great price. I got the 27 as there are more pixels than the 32, so better for LR and PS.

This monitor is interesting. I’ve enjoyed my experience with it overall. However, it took me quite a while to figure out the correct settings to be able to use it. The default settings have extremely high contrast. Reds were appearing as some sort of neon red/pink color. I got it figured out after a lot of trial and error. One of the big reasons I got this monitor was so that I could use a single usb-c cord for charging (Mac) and attaching to the monitor. Unfortunately, the monitor doesn’t provide enough power to actually charge the computer. It just dies much more slowly. I use it as my home office computer (graphic design) and it lasts for the whole work day, usually. Then I have to plug into the original charger at night. I didn’t think I would have to do that, so that was a little let down. Anyway, it’s a great monitor overall. Just has a few hiccups that can be worked through.

UPDATE: April 25, 2021: Running into problems with USB-C cables longer than the supplied LG 12 cable, I decided to try Apples cables, since Apple is well-know for making high quality products. First I tried Apples (thin) 1 meter cheaper USB-C Charge Cable. That cable did not work. Next I tried Apples (thick) 0.8 meter more expensive Thunderbolt 3 (USB-C) Cable. That one works fine. I noticed with all the USB-C cables I have tried, the thickness of the cables that work are much thicker than the cables that did not work. Another benefit I was not expecting is that with the good-working thick Apple Thunderbolt 3 (USB-C) cable, all of a sudden my Apple Watch began unlocking my Mac properly. Go figure that one out!! ============================================ This is a wonderful monitor. HOWEVER, if you want to use a USB-C to USB-C cable that is longer than the supplied 12 LG cable, you might not be able to do that: While the supplied 12 LG USB-C cable works fine with my Mac mini M1, I need a longer cable. I tried one of my 3 USB-C cables and it does not work. The Q&A here also shows at least 2 other buyers having the same problem. Thinking it might be a poor quality cable I ordered 2 x 3 Anker USB-C cables: they also did not work. I then tried another of my 3 USB=C cables and it worked. Unfortunately I do not know what brand it is, or where it came from. I just got off the phone with LG support. They could not provide me with a solution for obtaining a USB-C cable that is longer than their supplied 12 USB-C cable. (I am not interested in using an HDMI cable.) LG support repeated told me that any other 3 USB-C cable should work. But clearly not all of them do. I was surprised that even the Anker USB-C 3 cables did not work. LG support also repeated tried to tell me that a *12* monitor cable is the standard length. That, of course, is ridiculous. Its a shame I had to deduct 1 star due to this problem. YMMV Otherwise, again, this is a wonderful monitor.

This is used with a Mac Studio. It is incredible quality and worked out of the box with no issues. 100% worth the price.

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.

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.
