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

Like a lot of people, I was trying to find the perfect 4k monitor with USB-C capability to have a display for my MacBook Air M1. This monitor is great because not only is the text sharp but it also charges your MacBook. This is easy to use and worked straight out of the box.

Screen quality is great but read below: After months of having this monitor and too late to return it. I was looking for split screen or PIP with different sources connected to the monitor inputs and found out it does not exist. to my horror. I never imagined a $750 monitor would have this feature missing. My crappy $200 Samsung has this feature in the menu settings and so does my other LG.

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.

I have two LG 27UN850-W 27 Inch Ultrafine UHD (3840 x 2160) IPS Display with VESA Display HDR 400, USB Type-C monitors set up side by side. They take up a lot of real estate, both with the width of the monitors and with area consumed by both bases side by side on the desk. Takes up at least 8 inches from the stands vertical base to the tips of the semi-circular stand. Now imagine double occupancy for the dual monitors. So thats room you wont be able to fully utilize for other more desirable tasks. The monitors themselves seem to operate fine. Does have a pop-up window that appears ever so often that the cursor wont seem to engage the action button. Cursor disappears when trying to click on the window. But a main point that I want to stress is that you need to have a graphics card on your computer/source system thats adequate enough to push dual 3840 x 2160 displays if you want to take full advantage of the monitors capability.

Ive had this monitor maybe two months and am experiencing some issues already. I did a lot of research before choosing this one as I really wanted good screen real estate for my Macbook Pro; excellent picture quality; a monitor that would support charging my laptop while connected. Heres how that worked out: 1. Picture quality is good, a bit bright but good. 2. The charging only works on occasion. Sometimes the monitor charges the laptop, sometimes it doesnt. This is really frustrating to me as my office is tiny and I dont want additional cables. It also connects, for the most part, but I will get the occasional black screen that doesnt detect the laptop. I have to then open the laptop and make sure the monitor realizes its on and close it again. Its annoying at best. 3. I cant control the sound from my laptop. This is wildly annoying. Not sure if Ill return this or if theres better out there, but for the price I paid I would expect it to work a lot more consistently.

I took a risk and bought a used monitor for about $280 and it is solid budget monitor for GREAT VALUE. I had tempered expectations and was initially concerned about it used, but monitor was practically brand new. I got my values worth. Condition came in brand new, 4K resolution, 60hz standard, color is nice for entry level video editing, gaming is great for non competive games, and selling point for me is the USB-C to connect my M1 16in PRO. I would do this again.

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.

I purchased this after returning the Samsung M80B as it gave me a headache. This thing had perfect color (for my needs at least) out of the box. Pros: Easy to set up Tons of connections options Stand has the perfect tension for going up and down Picture looks great even if the blacks cannot get as dark as a VA panel Very easy on the eyes Cons: I dont like the control button placement on the bottom. I have a controller that I have to move every time I need to get to it Contrast is not quite as rich as the Samsung VA panel I returned Not a native resolution to my Mac Studio although I dont have the wallet for the 5k version

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.

UPDATE 11/2022: As long as you take care not to jostle the cord once inserted in the back of the monitor, it works pretty consistently. After plugging the USB-C into the Mac, its important to wait to hear the connected sound, look for the battery icon to show the charging lightning bolt, and only then close the laptop to put it in clamshell mode. If you dont see the charging lightning bolt, the monitor screen will go dark when you close the laptop. __________________________ I purchased this monitor to work with my M1 Macbook in clamshell mode, and that requires the laptop to be powered. The monitor connection is supposed to power the Mac. To be clear: if the MacBook isn’t receiving power when closed, the monitor goes dark. As numerous other reviews have noted, theres something defective about the hub input for USB-C. It works about 50% of the time, no rhyme or reason. Youll hear the connecting tone, then it disconnects, then it connects, then disconnects. From reading other reviews, its no use getting the monitor replaced, because the replacement will have the same problem. I was out of the return period when I realized this was happening. Lesson learned: when you get electronics, use the f&*% out of them right up front, to make sure theyre going to work in the long run. Other downsides: (1) it’s so bright I can only use it at the very lowest brightness level (and I use Flux to dim the screen in lower light); (2) you must manually adjust all settings using a button under the screen. For instance, the brightness buttons on your Mac will not function.
