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

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!

Great for accounting. Very clear and bright display.

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.

I bought two of these monitors: 1. The first one is to connect to a Chromebook for distance learning (via USB-C) and a Kano (via HDMI) for tinkering with code projects. The monitor works great and charges the Chromebook over the USB-C connection. The audio is adequate and is substantially better than the audio in the Chromebook. 2. The second one is to connect a MacBook Pro (via DisplayPort 1.2) for office productivity and watching 4K HDR content and a Dell Optiplex (via HDMI) for office productivity, gaming, and watching 4K HDR content. These monitors perform flawlessly in my two environments! I enjoy the flexibility of having USB-C, DisplayPort, and two HDMI ports to choose from for my inputs. Having these monitors with the built-in adjustable stands allows us to position everything ergonomically to prevent neck and eye strain. Ill update this review in the future after weve used these monitors for a few more months.

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?

I highly recommend two large computer screens for internet use. This one was easy to hook up and looks good and is small enough to fit under my shelving. A previous different brand screen failed after a few years. I am hoping this will last more than a few years. It is a LG which we have had good luck with with our TV. Hopefully Amazon will ask me in five years whether this is a good product. It is crazy to ask in two months whether this will last!!!!!

My negative review is only concerns Mac connectivity. The USB-C connection only powered my two Macbooks but the monitor itself was not detected by MacOS at all.

Per se, its a good monitor. Decent picture quality, very high resolution, sharp image (its 4K after all), easy to mount and set up. Huge panel with a lot of real estate which is always welcome. If you dont compare it with anything else, you will be quite happy with the monitor. BUT: I was expecting it to replicate the LG ultrafine sold on Apples website for me. I already have one of those monitors in my office and was hoping to have the same experience at my home office too. Same manufacturer, apparently same technology, similar specs, good to go, right? But its where the disappointment began. The image quality, the sharpness, the brightness, and the color delivery come nowhere near like that. Even the build quality is inferior: The plastic frame, cables, stand, everything feels less premium. I have no idea if theres any fundamental technological difference between the two panels, or its mostly a matter of firmware/software, but Id go for that Apple-overpriced ultrafine LG panel any day. MACBOOK PRO USERS BEWARE: This monitor has problems with MacOSs HDR. Right off the bat, its activated, shocking you by a pinkish downright garbage image quality once you turn on the monitor and connect it to your Mac. Either Apple or LGs fault, youll need to disable it to get a decent image profile. Thats all I came across through my hours of googling to fix it. (What? I didnt buy a half-a-grand HDR monitor only to disable it!!) VERDICT: Quite disappointed since I expected more based on reviews etc. Still debating between returning it - as much as I hate returning stuff due to the environmental impacts etc - and going for an LG ultrafine from Apple, or keeping it and trying to be happy with it. UPDATE (1 month later): Decided to keep it and give it time so it has a chance of growing on me. Im now quite used to the image quality. No big complaints anymore. The HDR problem with MacBook is still there, even after MacOS 11.4 update. No big deal though as long as you keep it off.

I have tried three different 4k monitors and this one is hands down the only usable one (probably the best under $400). Its totally compatible with my M1 Macbook Pro, and give good use experience when plugged in. Picture quality is really nice and I have nothing to complain about it.

I was looking for a monitor for coding and this LG monitor is just doing its job - text looking crisp and clear, text background is not hurting my eyes and it is just looking like a good monitor.
