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

I bought this monitor to act as a secondary screen for my M3 MacBook Pro as well as a dedicated screen for my older touch bar MacBook Pro with a damaged screen (using it in clamshell mode with a bluetooth Anker keyboard and a Logitech mouse). The quality of the monitor is great, and it's not overly heavy for a 27 inch monitor. It's large enough I could multitask different windows comfortably. The color is great on the Ultrafine, and the 4K resolution looks just as good to my eyes as the native resolution on my M3 Pro MacBook despite the monitor having a max refresh rate of 60 hertz vs. the laptop's built-in 120 hertz display. Having the AMD FreeSync mode built in for gaming does help it look smooth when running games on my computer or my Nintendo Switch (I have yet to try it with my PS5). The USB-C connection on this helps minimize cable usage, as it does charge my laptop at 60w.

Was using Dell u2415 that seemed pretty good for the new Mac mini (8/256) I just got, using HDMI. Dell screen had a few areas that were getting image burn or something, so searched for 27 in 4k replacement. Biggest question was would I notice a significant difference if did get a 4k, well the answer is yes. I got 27UN850-W since I don't need 90w or 60w charging. Not a gamer, not a photo proofer, not a content creator. This screen is really nice, the text is much sharper and clearer, and my eye are not bugged out after extended viewing like they were on the Dell. Cost an issue, oh yeah, the apple display was not happening. Really anything over $400 wasn't happening. Do I need a USB hub, no or ethernet in the monitor-no. Ran the included USB-C cord from the Macmini to the LG screen turned everything on and wow how nice the screen looked. It shows up in system as LG HDR 4K with color profile LG HDR 4K 60hz. It looks super excellent to me. Did try changing the resolution to I guess it was true 4K and everything was sharper, but needed a magnifying glass to read it, so I went back to that original setting as it was perfect. Looking in Hardware Graphics/Displays this is what my Mac was reporting: LG HDR 4K:Resolution: 3840 x 2160 (2160p/4K UHD 1 - Ultra High Definition)UI Looks like: 1920 x 1080 @ 60.00HzIt is silent just like the Macmini. Still quick and snappy. My windows machine has W11 and attach it via HDMI. The joystick control on the LG makes it easy to select what input to display and I had to play with that because it defaulted to some high resolution with 30hz! Everything was really choppy, got it set to a lower resolution at 60hz. This screen will go to sleep with the Mac, and wakes up fast no issue. The included speakers are set with Maxx sound on-which is an attempt to make them sound better-and they do get quite loud, but they are small monitor speakers, and would only be good for voice. At low volume levels music would probably be ok, but I am not using them, and using a bluetooth speaker for way better sound. Stand is stable for me, really easy to put together and get going. The power brick is hidden under desk, not a big deal that it is a small block, cord is plenty long. Well packaged. LG delivered a very nice screen for the money with this one. Super happy that it was plug and play with the Mac, and operates correctly with the Mac. It's a keeper for me.Update April 26 2024---------------- Quick update after using it daily for the last 6 months. No change in opinion, no buyers remorse, no screen issues, still easy on my 60+yr old eyes. Sometimes when reading text I really notice the detail and sharpness and get that happy feeling.

I have four 4K monitors:LG 27UN850-W X2, one desk dual monitor setup (will be referred below as LG)Dell U2720Q X2, one desk dual monitor setup (will be referred below as Dell)I use LG, my spouse uses Dell.In my mind LG is better to fit my needs.From my spouse's point of view, Dell is preferred over LG.1. Why does LG better fit my needs?a) both LG and Dell have anti-glare screens. But I found Dell reflects a little bit more than LG. I have a “designer white” desk. Dell’s reflection is noticeable especially during the evening when using the desk lamp and watching videos. On the other hand, LG does not distract my attention due to glare. The Dell glare issue could be a combination of my desk color and light source setup. But given the exact same setup, LG does not distract my attention due to reflection.b) LG has ports arrangement on the back, rather than at the bottom. I’d like to try different gadgets during the past weeks. The LG’s design makes it super convenient to plug/unplug cables, firetv stickers. Dell’s traditional port design also works well thanks to the best ergonomics stands (will come to it later). Adding devices/cable to Dell just by simply rotating the screen.c) LG has a user-friendly screen control joystick. Dell’s traditional button is not comparable. Again, because I’d like to change settings, and try different gadgets.2. Why does Dell better fit my spouse's needs?Ergonomics, ergonomics, ergonomics!My spouse needs ergonomic monitor stands. Dell’s design fits the bill perfectly. A complete freedom of adjustment with extremely wide ranges, at any direction.3. What do the two monitors share in common?They are all very good monitors for regular day to day work/entertainment. Again we are not professional graphic designers nor video editors. For average users like us, you cannot go wrong with either LG/Dell. For most of the time, all our monitors work in reader/office/text mode. When it comes to entertainment, LG/Dell, for me, do not make much difference. I cannot tell the difference when watching videos or playing games, or editing family photos. They look pretty much the same for casual entertainment. I also placed the LG/Dell side by side, playing the same youtube 4K HDR videos with all monitors in full HDR settings, but I cannot tell which is better. They all calibrated to their own standards. In their own “reference frame”, they all look very beautiful.Btw, isn’t the best entertainment to find a job to do what you like? The office/text mode might be the best entertainment mode for me :-)Finally, because this is my serious review under this LG product tag. I will add 3 more points for LG only:1. LG has a bulky voltage transformer shown in the picture. The power cable on each side of the voltage transformer is about 55 inch (total about 110 inch including the transformer in the middle), long enough for any home office setup. However, for a standing desk, I have to spend a bit extra effort to hide the bulky transformer in the cable management tray.2. One of the LG monitors has a very tiny issue with the stand. I returned it and bought a new one. The problem went away.3. LG has a builtin speaker that can be easily used with fireTV stick 4K, just plug and play. If I want to control volume, I’m using the LG monitor joystick, or a separate speaker or a bluetooth (Jabra evolve 75), where output device with builtin volume controls. The joystick also makes the hdmi input switch very easy, fireTV to Nvidia Quadro, very smooth joystick operation. But better to get a 4K HDMI switch.
