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.

If you need a screen that would turn your MacBook into iMac experience, this is what youre looking for.

I have been using this for a few months and I am very pleased and satisfied with the quality.

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!

Had it paired with my Mac Studio. Like the color and text, but the back of the monitor looks very cheap. It’s not a pretty white/silver plastic. I end up returning it.

Ive been looking for the perfect monitor for the past couple of years and didnt want to spend all that money on the new Mac studios. I finally took the plunge with this monitor after extensive research and Im so glad that I did!! This a GREAT option for graphic designers like myself as the coloring out of the box was good to go. I almost like it better than my Macbook pro display. Its also probably one of the few budget friendly monitors out there that not only has great specs but looks great as well. I wanted something aesthetically pleasing alongside my mac. If you do any design, photo, or video work – this monitor is for you!

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.

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.

Excellent screen resolution as used for the main screen for coding and creating in Blender with my 2019 MacBook Pro 16, but THIS IS NOT THE ULTRAFINE AS LISTED. I am still keeping the product as it is a great price for the quality, but buyer beware! The built-in speakers are not good when compared to the built-in speakers of the MacBook I am using. Also when it is first hooked up make sure to uncheck High Dynamic Range in the settings so the colors actually match your built-in retina display colors.

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.
