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

I really struggled with the decision for what monitor to buy for my new Apple MacStudio computer, and was seriously considering spending another $2k on the Apple Studio display, but after reading ALOT of reviews I settled on this LG ultra fine 27 inch display and saved myself about $1500! It is a great display, plenty of brightness and clarity of color. From now on I’ll stick to Apple for my computers but there is no need to spend the extra money on their displays when these lower priced options are just as good!

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.

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 connect this monitor to my M1 MacBook Air and it works great. I keep the MacBook in clamshell mode and it charges nicely while using the monitor. There also seems to be a battery health think going on because it will go down to 80% and then back up to 100%. I think this is Apple keeping the battery moving and healthy. Would not hesitate to recommend this monitor to those in my situation. The con is that the speakers are not great - they are OK. Other than that - wonderful monitor.

Great for accounting. Very clear and bright display.

Bought following a bunch of online research in which I compared 15 different monitors. Ive been very happy with this monitor in the 2 weeks Ive had it. Works great with my 2020 M1 MacBook Air using the USB-C cable thats included with the monitor. (Finding a monitor compatible with that computer was a key deciding factor for me.) The picture quality is plenty crisp and a good deal for the $480 price I paid. Ive used the ~$1200 5K LG monitor that Apple recommends, but it has ghosting issues (traces of high-brightness content take a while to decay after windows are moved around) that made me question whether the 5K was worth the price. This 4K monitor feels like a solid value in a good price/performance niche and Im glad I chose it. I mainly use it for coding and day-to-day web/email/etc. with a bit of graphics work and its done well for me in all those categories.

For the $$, I cant imagine a better monitor. No hiccups at all. For keyboard brightness controls, you can find a few apps to accomplish that. I wish it had automatic brightness control, but OK. The curved stand base is stylish, but awkward on your desk.

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.

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.

I upgraded to this 4K monitor for photo editing and it is fantastic.
