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

Screen quality is great but read below: After months of having this monitor and too late to return it. I was looking for split screen or PIP with different sources connected to the monitor inputs and found out it does not exist. to my horror. I never imagined a $750 monitor would have this feature missing. My crappy $200 Samsung has this feature in the menu settings and so does my other LG.

This is by far my favorite monitor for my Macbook Air M1 2020. I love the colors right out of the box. I actually enjoy looking at this monitor more than looking at the screen on my Mac. The letters are so sharp and the colors vibrant. For the price, you are getting a high-quality monitor that makes the perfect friend for your Mac. I use Illustrator and Photoshop a lot and this monitor makes me stay focused on designing and be more creative. I highly recommend it.

I have tried three different 4k monitors and this one is hands down the only usable one (probably the best under $400). Its totally compatible with my M1 Macbook Pro, and give good use experience when plugged in. Picture quality is really nice and I have nothing to complain about it.

Theres no auto-switch for input source??? What the hell LG are we living in 2023???

I have been using this for a few months and I am very pleased and satisfied with the quality.

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 really struggled with the decision for what monitor to buy for my new Apple MacStudio computer, and was seriously considering spending another $2k on the Apple Studio display, but after reading ALOT of reviews I settled on this LG ultra fine 27 inch display and saved myself about $1500! It is a great display, plenty of brightness and clarity of color. From now on I’ll stick to Apple for my computers but there is no need to spend the extra money on their displays when these lower priced options are just as good!

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.

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.

First, when connected to my MacBook Pro 16, this is an awesome monitor. Setup was easy, and it gracefully handles being plugged in, and unplugged. The speakers on the back are even useful. Now for the bad. Theres no easy way to adjust the sound when the app doesnt present a volume slider. When using with Linux, it sort of works, but there are no settings that can place the monitor in some kind of comparability mode, so I get half a screen what is basically unusable. This means that in my dual setup, If I want to do development on Linux, I need to use another monitor.
