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

I spent a considerable amount of time researching monitors to pair with a new M1 Mac Mini. Years ago I did most of my work on an iMac, and when I upgraded to a Mac Pro I went through half a dozen different monitors trying to get that ultra-sharp, bright iMac retina display look on a 3rd party monitor. I landed on 2 of these 27UN850s to pair with the new Mac Mini. Im running 1 via Thunderbolt and 1 via HDMI, and both look pretty amazing right out of the box. Not quite the retina display type wow factor, but at this price point (less than $500 each) you really cant touch these monitors. I was also considering the Apple-endorsed LG Ultrafine 4k; but knowing Id be mounting these on an arm and without much need for the increased power delivery via USB-C, these were $300 cheaper (each) and look nearly as crisp. If I had one complaint it would be that the built-in speakers sound boxy and flat. Im not using the internal speakers anyway so its not a big deal for me - but if youre looking for any depth in your audio with these you may be disappointed. I dont think anyone expects monitors to have amazing sounding speakers anyway.

Writing a review for LG UltraFine 27UN850-W. I have been using it for about 2 weeks. Before this model, I bought LG 27U650-W which was the same price in BestBuy as 27UN850-W here, and when I found out i returned it back because its double more the price in BestBuy. LG 27UN850-W is a very good monitor. It produces nice colors. The 4K resolution is great, it produces crisp fonts, good visibility of icons and overall accurate images. The brightness is very good, up to 350 nits when the brightness is 100%. HDR is not good it produces very sharp edges which do not look good. Contrast is 1000:1 which is ok but its not the best. This monitor cannot compare to 4K or 5K Apple monitors, however it is very close to them. More expensive monitors about $800-$1000 would probably output same image and contrast quality as Apple stuio monitors. I found for me the best image and contrast quality for this monitor on Vivid settings with brightness of 85%. Overall, this monitor is very good for office work, it is also good for photo/video design and I am sure it is very good for gaming which I didnt try yet.

This review is for the LG 27UN850, which Ive been using for a couple months as a usb c monitor with the MSI Prestige 15 laptop. The one star reduction has nothing to do with the image quality, which is excellent for my non photography use. I knew the short comings of the monitor, and I still bought it, because its such a good value for the price. The shortcomings in my use are: 1) No hardwired ethernet connection on the monitor. No big deal if you have primo ethernet into your location and good wifi coverage. I dont, and need a hard wired connection. This causes you to burn one usb c port for use as an ethernet connection or a full blown extra usb c hub. 2) Only 50W charging capability. The MSI Prestige has an 82W battery, and can go dead, mainly while gaming, unless the dedicated usb c charger is used. So I need 3 usb c ports on the laptop to fully cover my needs, but as in most laptops, I only have two. 3) I found out, and using a youtube found fix, issues related to laptop battery profiles when using usb c external devices like this monitor. It drove me crazy for a while, the constant ding of disconnect, then immediately ding for reconnect. Not the monitors fault, but fault of usb c mode connection. I havent tried using usb c to display port connection with this monitor, and dont know if that mode would solve some of the problems. A Windows 10 shortcoming when using the monitor as a second monitor. There is no selection to allow the laptop screen as Monitor 1 and the LG as Monitor 2, using them independently. You can either mirror, or use 1 alone or 2 alone. As for big plus, I love the joystick for manipulating all the monitor functions. It took a few days to warm up to it, but now monitors with a row of buttons seem old fashioned and hard to use.

Purchased this monitor for my M1 Macbook Air and Xbox Series X. I love being able to connect only one USB C cable to my mac for power and video. The control knob is simple and just works. The monitor has a great port selection but I have not tested the USB hub for transfer speeds with my laptop. The stand feels solid and I like having the monitor up higher so my laptop screen can be open directly beneath. The included cable management clip is cheap but it works well enough. Hopefully, this monitor lasts me for years as Im a big fan. Works great for 4k @60hz on the Xbox Series X.

Color looks exactly the same with my Apple devices

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.

After much research, I ended up buying this monitor graphic design. I watched a ton of videos and read so many reviews. Nothing seemed perfect...as what I really want is my old Apple Cinema 27 cinema display! (Ive been through 2 of those and both didnt work well with my new MacBook pro. The connection wasnt reliable and the screen would blackout. I got rid of both of them and decided I needed to move on.) This monitor was really the only one I could stomach from an aesthetic point of view, but I was worried because I read about some of the color issues in the reviews. I was looking to spend under $500. The Dells are highly rated, but they were more expensive and not as nice looking. Onward to my experience and addressing some of the issues I saw in the reviews: 1) Some reviewers said the stand is flimsy. Its not as great or solid as the mac stand, but its fine and sturdy enough. No issues here. 2) One reviewer mentioned that her display was tilted a bit and she couldnt get it straight. Mine was tilted a bit, but just put a little muscle into it and got it straight no problem. 3) The font on the display was way too large. I found a setting in systems preferences to make it smaller, looks normal and crisp now. 4) A few mentioned that the color is off, they are too bright and saturated, almost neon. I did experience this. In order to fix it, I did as some reviewers recommended and turned off the High Dynamic Range setting in the display preferences. 5) Also, It was confusing when I first plugged in the display. A menu associated with the display (so not controlled by my mac) was asking me to select ok. Without my cursor from the mac, I couldnt do this. That is when I discovered the important power switch and setting switch on the monitor under the LG logo. The controls on this switch are very clunky, but after spending about 15 minutes with it I could see where I can adjust the brightness and some other settings. 6) This monitor comes with speakers, but you cant control the sound from your macbook pro. Since Im using this at home for work, I was frustrated when I wanted to listen to a podcast and the sound came in through the display too loud. There is an adjustment with the settings under the LG logo on the display, but thats a hassle. So I went into system preferences on my Mac and changed the setting back to MacBook Pro Speakers, so now the sound is coming through my MacBook and I can easily adjust the sound. So if you are like me and using this for work/design, you might as well save some money and get the version without speakers. So the bottom line is it took about an hour to fiddle with settings until I got a good-looking image that matches my MacBook Pro. I just got the monitor today, so Ill add to this review if I come across any issues. (I dont add to this it means that I like the monitor and its working fine for my needs as a graphic designer.)

DCI-P3 98% coverage, brain dead color calibration, 4k, 32in, and the blacks are similar to my va monitors. Checks all the boxes off my list. The refresh rate could be higher but that doesnt matter for my work so this is a 5 stars from me. Nice value from what I can tell.

I just got this monitor the other day and the pic quality from what I was coming from which was a old 1080P monitor 4K is amazing so far it is better then I expected and very bright I will update my review if anything comes up that is not positive but so far it is awesome !!!!!

I converted from a PC desktop to a Mac Mini and paired it with this monitor. It was a worthy investment. I spent hours (probably too many) researching this set up. Do yourself a favor - just buy it. The only gripe I have is that some web designs and UI/UX code shows up a little grainy because its not set up to be displayed on a monitor with this many pixels. Haha. Ill take that trade off. Ive got it mounted on my desktop right now, but in a few days Ive got a monitor arm coming which Ill set up. Thatll be about it for my monitor set up. Ill probably end up buying another tbh.
