    • Fabulous and worth it
Display Size: 27 Inches
Fabulous monitor. Expensive. Worth it if you’re a Mac person.

    • Great solution for a Mac display
I've used this monitor for about 2 weeks. Very satisfied. The 24" size is perfect for my use. After decades of using two computers, a desktop iMac or Mac w/monitor along with various MacBook Pros, etc. - I wanted to consolidate down to one Mac. I purchased one of the new M2 MacBook Airs, connected the LG monitor via the supplied Thunderbolt 3 cable and voilà - instantly worked. Single cable solution. I connected several hubs to the monitor USB-C ports and all the various peripherals (external drives, printer, etc). Screen quality is indistinguishable from the 21.5" 4K "Retina" iMac I previously used. There have been comments about the LG monitors versus the Apple display options. Appearance, the stand, build quality, etc. The appearance is fine (IMHO), may be not as refined / pretty as the Apple studio display but looks great with my new midnight MacBook Air. The stand is quite heavy and and the 24" display is very stable and doesn't move or wobble. The build quality seems fine. (think LG TV) Reliability TBD. My only comment is that some people have had failed / intermittent connector problems with this or the 27" version. The back panels are slightly angled and the connectors plug in at perhaps a 10 degree angle. Reaching around back I'd see people, including myself, trying to put in the connectors off-angle. To minimize potential issues I plan on plugging cables in once to the monitor (I.E. not changing connections all the time) and connecting / removing devices from the other end of the cable connected hubs.. Last - no webcam, microphone? I don't use these often and the notebook has them when I need it. This would be a different story with a Mac Mini or Studio. So far this monitor more than meets my expectations. ... show more

    • A more affordable alternative to Apple 5K displays
Display Size: 27 Inches
I got this display to accompany a new Mini, both replacing an aging iMac with 5K display. It was easy to set up and has been flawless in the 10 months since buying it. I actually like the stand better than my old iMac's because vertical height is easier to adjust. It plays nice with my DAS keyboard's display controls and after cataract surgery in 2023, I really began to fully appreciate the crispness of the LG's display—allowing me to discern periods from commas once again! And of course, watching movies and other streaming media, the LG looks fabulous. ... show more

    • Do Not Buy for Mac
Display Size: 27 Inches
while the monitor looks good, it had problems out of the box. SSDs connected to the monitor eject unexpectedly causing errors. The monitor also caused kernel panic when my M2 Mac Mini goes to sleep. The LG support page unhelpfully suggests setting the Mac mini to never go to sleep. I'm using the thunderbolt cable that came with the monitor, and I've tried switching cables. I've tried switching Macs too. LG needs to do a better job. ... show more

    • Difficult to find a higher quality monitor, but . . .
Display Size: 27 Inches
Have been using this monitor for about two weeks and enjoy the superb resolution and build quality. Only complaint is that the monitor periodically goes blank or into screensaver mode while I'm working which is totally unacceptable. The only way to restore the video is to unplug the thunderbolt cable and reinsert it. I know it's the monitor and not the M1 Mac Mini, because when the video is restored, I can see the results of my blinded keystrokes. Contacting LG for support was worthless. I'm hoping to discover there is some setting that needs to be tweaked in order to prevent this behavior. In the meantime, I've started the return process since for the money, an unreliable monitor is not acceptable. I've got a month to figure it out, but no tech support to rely upon. Update 1/9/21: Increasing to 4 stars. Would go higher if there were more ports and a narrower bezel. As it turns out, the issue with the screensaver popping up unexpectedly has more to do with Big Sur than the monitor. The problem occurs about 20 minutes into using the machine. Apple is working to resolve the issue which also can be mitigated by avoiding the login window. I have multiple users, and the recommended approach to switch between them is the quick switch option in the upper right of the OSx Toolbar. Apple also provided the following command which must be run from an Admin account and followed by a reboot as a stopgap measure to correct the problem. After about a week of additional use, the issue seems to have gone away. sudo defaults write /Library/Preferences/com.apple.screensaver loginWindowIdleTime 0 ... show more

    • Beautiful image, easy connectivity for Mac
Display Size: 27 Inches
This monitor is the same panel that is used in the iMac 27" 5K. Which is to say the best commonly-available panel short of the super-expensive Pro Display XDR. Text and images are clear and sharp, noticeably more so than a 4K monitor. It gets as bright as I can stand. Its included USB-C ports allow me to use it as a hub to connect USB-A devices via a hub, so I can use a single cable to plug my Macs into all my peripherals. Just like the notch on the new Macbook Pros, the plastic frame and thick upper bezel disappear in daily use. I use this monitor with my work 16" Intel MBP and my personal 14" MBP M1 Max, and as a monitor it is flawless with each. Adjusting brightness through the Mac keyboard rocks. I've only noticed two drawbacks: It has no headphone jack support, so to connect headphones to it, you must use a USB-C - 1/8" adapter. I'm using Apple's version of it, but it emits loud pops every couple minutes or so if there is no sound output. The other problem is that the monitor won't daisy-chain another monitor as far as I can tell. When I plug a low-end monitor with a USB-C - DisplayPort cable into one of the monitor's downstream ports, the Mac complains that a Thunderbolt connection is required. ... show more

    • The best alternative to Apple's version
Display Size: 27 Inches
Wanted a reliable 5k and this is the deal...in fact, this used to be sold at Apple before they came up with their own version. Adjustable...5k....plenty of ports....been using these for nearly two years and have not issues with them.
