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

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.

Easy - connect your PC with display port, use one of the HDMI inputs for your 4k Roku stick, do some PC tasks, then take a break and watch a movie on Netflix or Amazon. **Nice bright picture with HDR. You can adjust picture mode individually in display port, and HDMI, etc. I have it set for HDR effect for both DP and HDMI. **Having an IPS panel means super rich, and vibrant colors. **Also, 350 nits of brightness is plenty bright for HDR! Note: This LG 27UN850-W 27 Inch Ultrafine UHD Monitor also has a USB C-port that can charge your laptop or cell phone. Allows you to display whats on your cell, or laptop directly on the monitor just by plugging into the USB C-port, while also charging the connected device. ***I have NOT used the USB C-port yet, as I purchased this monitor mainly for connecting my Dell desktop PC using the Display Port, and for using my 4K Roku stick (HDMI port) for watching NETFLIX and AMAZON Prime movies. To find out more about this monitors USB C-port (a great feature that other monitors DO NOT have), watch some YouTube reviews.

Works really good using USB-C direct from MacBook Air. Screen quality looks almost as good as my iMac Retina 5K. The size of macOS menu items at top and and dock icons on bottom and screen work-area area -- all were as expected and as appear on my iMAC. On HP monitor I bought first and am not returning all these were totally distorted. I read this monitor works well with MACs and it sure does. Monitor controls work via little joystick which is really slick. Screen hight and tilt operate very nicely also. Good quality USB-C cable included. Super beefy AC adaptor also which I guess is good? Excellent for MACs!

Have been using this for a few months now for my M1 MacBook Pro. This works great and has the benefit of being able to connect to the MacBook using a single, USB-C cable. Pros: - the picture is nice and clear - works flawlessly on M1 MBP - IPS Cons: - Wish the refresh rate were higher than 60hz - Wish you could daisy-chain these monitors together I feel the pros outweigh the cons. Love this monitor and would purchase it again for my WFH setup. Not recommended for gaming.

I recently bought the LG 27UN850-W 27 Inch Ultrafine UHD monitor as an additional display monitor for my Mac Laptop. I was frustrated by the small size of my laptop and used to get neck pain due to it not being ergonomically suitable for my posture. I wanted something that will as clear as my Macs Retina display. I looked at several monitors but most were either low on Image resolution or unreliable. I chose LG because of its 4K resolution, the screen size of 27 inches and the value for money. Ive now been using it for around a couple of weeks and I love it more with each passing day. Its quiet and silent and theres no flickering. I connected my new MAC using USB C and my old Mac using HDMI. The monitor will prompt you to change the input mode in case you switch from one laptop to another and thats a lovely feature! The LG 27UN850-W 27 Inch Ultrafine UHD monitor is available at Amazon at a competitive rate and meets the quality and image resolution parameters pretty well.LG is also a Partner for Mac so I knew LG will be a good investment.

Update 8/16/2021: one display has developed two vertical lines of dead pixels after less than a week of use. This was a Warehouse returns, so the fault lies more with Amazon than LG. I purchased a pair of these 27UN850-W displays, and they perform as you would expect from a mid-range IPS display, good color accuracy, wide viewing angle, and no dead pixels on either. For productivity work, these are perfect. 60hz refresh rate isnt going to cut it for high-end gaming although Freesync will help there. Color accuracy isnt going to be sufficient for professional design and video editing. Certified for HDR400, but know that this definitely HDR-light, if you HDR is important to you, look elsewhere. Didnt try the monitor stand, but VESA mounting worked as it should. Left, right, and top margins are about 1/4 so for multi-monitor setups you will have about 1/2 boundary between workspaces. For dual monitor work scenario for documents, GIS, code, and the like, flat panels with a wide viewing angle like these are quite good. For me, these were an excellent value from Amazon Warehouse (Used - Acceptable), where these like-new displays that are missing bonus materials cost under $300. At MSRP of $450, these are a fair price.

Although I am aware this is a productivity monitor first, I was in the market for a 4K60 Monitor that could game well and would not break the bank. I am used to gaming on console so 120FPS support was not something I required as I am satisfied with 60FPS. I did endless amounts of research on various brands in this pricepoint to figure out what would be the best monitor in terms of screen quality and response time. This specific model did not have many reviews in terms of gaming performance, however I did know that LG makes great gaming monitors, this one has a game mode, and I was already looking at the LG 4K model priced below this one. When this model went on sale, I took a risk and purchased it over other highly praised monitors in this price point not knowing if it would be good for gaming, and I can answer that YES it is! Starting with screen quality, brightness is great, contrast is beyond expectation, white, gray, and black uniformity are all top notch, with little to no IPS glow. Colors are accurate and the resolution keeps things sharp. No complaints. For gaming, when you put this monitor directly side by side with a high refresh gaming monitor, it is extremely noticeable that this will not be as fast of a monitor as something gaming dedicated in terms of response time, however it is much more responsive than a normal 60FPS TV or other productivity based screens. I also have a 15 inch macbook retina display, and the response time on this monitor is atleast twice as good. Unless you are an ultra competitive high refresh gaming enthusiast, you will not notice any kind of input lag or poor pixel response in this monitor. It is just as good or better than playing console on a high end TV, and in gaming scenarios, I personally can not tell the difference between the response time on this monitor and my LG gaming monitor. It is only when using UFOTest that the difference becomes very apparent, and this mainly comes down to the difference in FPS. If I ran my dedicated LG gaming monitor at 60FPS, the response would be about the same. In short, if you are used to gaming on console with a TV and are looking for a responsive 60FPS display to prioritize image quality and play mostly singly player games with high settings, get this one and you will not have any regrets. If you are looking for the fastest thing in gaming and play mostly multiplayer competitive games you shouldnt even be reading this review. If you CAN afford it, I would highly recommend a 4K120 gaming monitor for the best of both worlds. In this price point with realistic expectations in mind, this is a fantastic monitor!

The picture quality is excellent. However, I tried to daisychain this to another monitor and couldnt get it to work. I wish LG had better instructions regarding this. In general, the menu buttons and design could use improvement. Over all, Im sort of happy with it.

Got this for my home setup to replace my LG Ultrafine 4K at the office. Figured Id try saving the company a few hundred bucks. When I first hooked this thing up it looked godawful and was ready to put it back in the box and shell out for another Ultrafine. Colors were awful, with brighter colors almost fluorescent and edges looked like someone had run a Photoshop Unsharp Mask over everything on my screen and cranked it up too high. But playing around with some settings, I found an HDR setting that is defaulted on. Turning this off, and then cranking up brightness to 100% and reducing contrast has this now looking about 100% better and almost indistinguishable from my $700 Ultrafine. To a more attuned and calibrated eye, the differences may be more substantial, but my eyes arent bad and I dont require any kind of insane level of color accuracy in my work so I am happy with this monitor, especially considering the cost difference. Also nice to have some standard USB ports on the back as we all know not every peripheral uses USB-C nowadays (and I had to have a couple dongles coming off the back of my Ultrafine) so dare I say I may actually prefer this monitor. The ID is not bad either. The frame is pretty minimal, and the stand doesnt take up too much space. Only consideration I didnt think about was that it doesnt have a built in webcam. So I ended up just picking up a $20 Logitech cam that plugs right into the back and works fine. If youre on the fence, and wondering if you need to spend more for a high end 4k chances are you probably dont.

I use macbook pro and this display is always connected to MacBook pro. In the first couple of months, the monitor worked fine with maintained speed. However, eventually it started acting pretty sluggish while working on common tasks like safari surfing, excel edits. I wouldnt recommend this monitor for heavy duty work where you are connecting with external keyboard, mouse and working on multiple software at a time. I really wished if the refund period was extended to larger period and not limited to just 30 days.
