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.

I have four 4K monitors: LG 27UN850-W X2, one desk dual monitor setup (will be referred below as LG) Dell U2720Q X2, one desk dual monitor setup (will be referred below as Dell) I use LG, my spouse uses Dell. In my mind LG is better to fit my needs. From my spouse's point of view, Dell is preferred over LG. 1. Why does LG better fit my needs? a) both LG and Dell have anti-glare screens. But I found Dell reflects a little bit more than LG. I have a “designer white” desk. Dell’s reflection is noticeable especially during the evening when using the desk lamp and watching videos. On the other hand, LG does not distract my attention due to glare. The Dell glare issue could be a combination of my desk color and light source setup. But given the exact same setup, LG does not distract my attention due to reflection. b) LG has ports arrangement on the back, rather than at the bottom. I’d like to try different gadgets during the past weeks. The LG’s design makes it super convenient to plug/unplug cables, firetv stickers. Dell’s traditional port design also works well thanks to the best ergonomics stands (will come to it later). Adding devices/cable to Dell just by simply rotating the screen. c) LG has a user-friendly screen control joystick. Dell’s traditional button is not comparable. Again, because I’d like to change settings, and try different gadgets. 2. Why does Dell better fit my spouse's needs? Ergonomics, ergonomics, ergonomics! My spouse needs ergonomic monitor stands. Dell’s design fits the bill perfectly. A complete freedom of adjustment with extremely wide ranges, at any direction. 3. What do the two monitors share in common? They are all very good monitors for regular day to day work/entertainment. Again we are not professional graphic designers nor video editors. For average users like us, you cannot go wrong with either LG/Dell. For most of the time, all our monitors work in reader/office/text mode. When it comes to entertainment, LG/Dell, for me, do not make much difference. I cannot tell the difference when watching videos or playing games, or editing family photos. They look pretty much the same for casual entertainment. I also placed the LG/Dell side by side, playing the same youtube 4K HDR videos with all monitors in full HDR settings, but I cannot tell which is better. They all calibrated to their own standards. In their own “reference frame”, they all look very beautiful. Btw, isn’t the best entertainment to find a job to do what you like? The office/text mode might be the best entertainment mode for me :-) Finally, because this is my serious review under this LG product tag. I will add 3 more points for LG only: 1. LG has a bulky voltage transformer shown in the picture. The power cable on each side of the voltage transformer is about 55 inch (total about 110 inch including the transformer in the middle), long enough for any home office setup. However, for a standing desk, I have to spend a bit extra effort to hide the bulky transformer in the cable management tray. 2. One of the LG monitors has a very tiny issue with the stand. I returned it and bought a new one. The problem went away. 3. LG has a builtin speaker that can be easily used with fireTV stick 4K, just plug and play. If I want to control volume, I’m using the LG monitor joystick, or a separate speaker or a bluetooth (Jabra evolve 75), where output device with builtin volume controls. The joystick also makes the hdmi input switch very easy, fireTV to Nvidia Quadro, very smooth joystick operation. But better to get a 4K HDMI switch.

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 shouldn't 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!
