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

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.)

This is a great looking display with fantastic color accuracy. It looks nice side by side with apple displays. The built in speakers are acctually pretty usable (laptop quality sound). The included stand is excellent quality. The Included USB C cable did not work with my m1 Mac. I Solved this by purchasing, a certified thunderbolt4 cable. This display seems to require a proper thunderbolt cable to work with m1 Macs. A usb c cable wont work. I am using in a dual monitor configuration with the secondary display from another brand connected via HDMI. Sometimes the LG display doesnt wake up. I deal with it by hitting esc key, to put the machine back to sleep and wake it up again. Id probably blame apple for the thunderbolt issues, so I am going to stick with 5 stars. This is a nice entry to a pro quality 4k display at the price point.

it darkens and dims, after a few minutes, so I decided to keep, tried to get partial refund but its impossible to get in contact with support, and I didnt want to return it. Seems like a problem with these screens, maybe not a common problem and I got a bad one

The monitor is great but there is a problem and Im wishing to get a reply from LG on this issue. So I need help. The HDR has the problem of slightly changing brightness while watching a movie on PC or playing a PS4 pro game in HDR, even when Smart Energy Saving is set to off(which is actually grayed out when in HDR mode) So I set it to off when in SDR mode, then I hop into HDR mode again and the option looks to be still off but it is grayed out(As if the HDR is not even considering that option when it is in use). So What exactly is this?. Is this Normal LG?

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.

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.

Color looks exactly the same with my Apple devices

I ordered this monitor hoping to save some space and money over going the route of a traditional 4K monitor and a USB-C/Thunderbolt docking station for my macbook. I was hoping to be able to use one cable for video, data and charging. It works, most of the time, but the USB-C features on this monitor have some frustrating issues. The monitor has issues charging my macbook, sometimes dropping the charge current to less than 10 watts, or other times stopping it entirely, which can only be resolved by power cycling the monitor. Im not sure what the power rating of the USB-A ports on the back of the monitor is. They work well enough with thumb drives, graphic tablets, keyboard & Mice, other low current items, but trying to charge an iphone from them causes a USB power error message to pop up. The audio output on the monitor is not always detected by my laptop, and often requires disconnecting and reconnecting the USB-C cable to get it to work. The mute and volume keys on the apple keyboard are disabled when using the monitors audio output which is a common problem with many cheaper digital audio interfaces, but is still frustrating when compared to dedicated desktop hubs, or USB-C monitors from Dell or Apple which still allow you to use these keys. I downloaded the software package from LG hoping that it would include drivers to enable these features or improve the reliability of the other USB-C features but it does not change anything. The display itself is gorgeous and I have no problems or complaint with it as just a monitor, but I think the USB-C implementation fails to justify its added cost over the displayport only version of the same monitor. Im making it work but will probably purchase a thunderbolt 3 hub eventually to hopefully handle charging and audio more reliably. I love the image quality of the 4k display but if I were to do it again I would either get the cheaper displayport only version of the monitor and an external hub or look at options from Dell or another manufacturer.

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.

Great color and clarity. Connects quickly and easily with my M1 Max Macbook Pro. I knocked off one star because the included USB C cable is pretty short and the monitor doesnt work with anything but the included cables. I tried 2 different USB C cables from Apple and a generic one and neither worked. I called LG and they said they dont make a longer one and that is the only one that works with the monitor. I use 2 of these monitors with my laptop so a longer cable would make it much more convenient to connect the one thats furthest away from the computer.
