[This review was collected as part of a promotion.] I recently upgraded to the LG 27UP850K-W, and I couldn't be happier with my purchase. This monitor is a massive upgrade from my previous setup in every way. The resolution makes everything look razor-sharp, vibrant and accurate—perfect for both work and studies. It's excellent for long hours of use thanks to the ergonomic stand and eye-comfort features, which really reduce fatigue. I'm happy that the USB-port works seamlessly, allowing my laptop to charge directly through the monitor (a game-changer). This monitor has elevated my workspace. Highly recommended to anyone looking for a serious upgrade!

Very Happy User!

[This review was collected as part of a promotion.] This monitor fits my desk perfectly. Got it to pair it with the Mac mini. The picture and colours are very good for my needs. The speaks are of poor quality but I didn't buy the monitor for the sound effects, have my air pods for that. Overall 5/5 from me!

Very good monitor

[This review was collected as part of a promotion.] Excellent picture and text quality. Once I mastered positioning the stand to push the screen back further using the onsite video, it has fitted perfectly into my work area.
Rather than having 2x24" monitors, my intended purpose was to have multiple pages open on a single larger screen; visible and workable at one time. This monitor has achieved my goal and significantly improved my work capacity and enhanced productivity.

1 instead of 2

[This review was collected as part of a promotion.] Awesome display. Super clear, crisp image, great viewing angle and good response rate. I have mine plugged in with USB-C to my Macbook and it works like a charm. When computer wakes up, the screen wakes up in seconds. If I switch computers, image switches – perfect. I have an Alogic Clarity 27 screen at work and it's a nightmare – using it with USB-C doesn't wake up the screen instantly.

I would highly recommend this LG. I love it

Super clear, responsive display with Macbook power

[This review was collected as part of a promotion.] Great quality screen, easy to assemble - I now own four for my team. The best feature is the usb-c end to end connection.

My team loves this screen.

The above is an excellent companion to my MacBook Air. The colour and image quality are excellent. The usb c hub makes it easy to swap between laptops without having to change charging blocks.

Excellent 27" LG Ultra Fine Monitor

[This review was collected as part of a promotion.] Fantastic screen! Bright & clear, perfect size for desktop. Easy to assemble and adjust once in place. Turns off automatically when not in use

Recommended!

Love it this monitor. I have photosensitive eyes and I am able to customize this screen to meet my 'low light', 'minimal eye adjustment' needs. It has made a remarkable difference in my comfort in front of the computer.

Great for People with Photosensitivity

[This review was collected as part of a promotion.] Excellent picture quality when connected to 2025 Mac Studio, despite supposed scaling issues when connecting a 4k monitor. Sharp and nice picture quality. 
Monitor stand and cable connectors are all good. Only minor aspect that could be better is the sound quality from the monitor. I stuck to using the Mac Studio speakers, which sound more natural/better.

Excellent 4k monitor connected to Mac

The screen is very nice.  My use is for photography so it is nice that it's calibrated and has good colour rendition.  The response on startup is a little wonky.  I connect  via USB.  If i leave the screen input selection to Auto the screen will display briefly and then go blank and eventually return.  I set the input to USB and this solved the problem.  The other problem arose recently after several months of use.  The USB hub connections have failed.  I have tried resetting but nothing works.  I would return this but it isn't worth it to me because I have other ports I can use.  If I really needed those ports I would return it and give it a lower rating.

Nice screen but . . .

I purchased this monitor in March 2024, and after only 16 months of use it already has dead pixels. I've used monitors from other brands (like Acer) for over 10 years without ever experiencing this issue, so I'm disappointed with the durability. Otherwise, it's a fairly good quality screen, though I wish it had adaptive brightness. Overall, I was satisfied, but not anymore, having dead pixels appear so soon feels like a sign of poor quality.

Dead pixels after a bit more than a year
