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.

Works great with my MacBook Pro. I am a photographer and the quality of this monitor is solid for 2K resolution. I wouldn't spend the extra $7-800 to buy a Mac monitor (in my humble opinion) I do weddings, video and modeling photography.

This was my 3rd one to purchase. I have 2 going vertical on my desk to complement my 5K 27" LG display. I got one extra for my employee to use and they are all very nice quality. I have had 2 for over a year no issues. Connecting with USB-C and very happy with everything. I don't do any gaming so I can't comment on that.

The newer version of this monitor was on sale for $30 less than the older version, but as I was doing my due diligence and looking into alternatives, the price went up. That was annoying, but at least the old one was still significantly less expensive than comparable monitors by other brands, and the reviews don't appear to be any worse. And the only difference between the older and newer versions is that the newer one supplies more power through USB-C, which is useless to me as I'm using it with a Mac mini. BTW, it seems connecting a desktop computer via USB-C causes problems, so it's best to use DisplayPort (via ThunderBolt/USB-C) or HDMI. I went with DP, because some users have reported that Apple's HDMI implementation uses YCbCr instead of RGB. But using HDMI saves you a TB port.Build quality could be better - all plastic, and a barrel connector for power. There is no power button, which is annoying - the monitor is either on, or in sleep mode (and it's quite slow to change states, also annoying). The joystick for navigating the OSD feels a little flimsy, but it works well enough, although I think I'd prefer buttons. It looks like there's barely any bezel at all along three sides (the bottom has a somewhat prominent bezel with the LG logo), but when you turn it on, you see that the other three sides have a black border that is effectively a bezel. It's maybe 1/3 the thickness of the bottom bezel. I can't comment on the stand, as I'm using it with a VESA monitor mount.The display looks great. The white point was a bit high, and the white point adjustment is too coarse. I don't have a colorimeter, so I manually adjusted the display as best I could to match my MacBook Pro. Someday I'll get a colorimeter, but for now, I'll live with the fact that it's not quite as accurate as my MBP or my old NEC professional series monitor. Also, I'm using the monitor with BetterDisplay, and I don't know if it looks any worse without it. It isn't as sharp as my MBP's display, or a 5K monitor, but it still looks very nice, way better than my old 1920x1200 NEC did when I plugged it into the Mac mini. The viewing angle also isn't as good as my MBP - I'd say it's good around 120˚, beyond that is when the picture starts to become difficult to see, whereas with my MBP, it's viewable practically 180˚. And as you move further away from 0˚, you'll see more and more of a white point shift. The anti-glare glass doesn't really help that much IMHO - it diffuses glare, but it just means you don't see a clear reflection; with a strong ehough light source, such as indirect sunlight via a north-facing window, it will still reflect enough light to make the display difficult to see.All in all, I'm happy with the monitor, considering the low price. However, LG is not known for making robust monitors, and I've had issues with both their monitors and their warranty department in the past. So far, the monitor has been great, but I've only been using it for ~4 months. Let's see how it's doing 3-5 years from now.

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.
