Let's say it plainly: for a Mac, the "correct" resolution for a 27"-32" monitor is 2560x1440, or 4x that for 'retina', which is a 5K display: 5120x2880.The correct resolution for a 20-24" monitor is 1980x1080, or 4x that for 'retina'

The main problem with this monitor is its resolution

The resolution is fantastic (I'm not sure what those complaints are).

Resolution is outstanding

Resolution is great and 4K video is jaw dropping.

Excelent resolution, works great with both Mac and Pc's.

- 4k 27” isn’t the right resolution for Mac OS, as another reviewer (Mr A.) mentioned

I’m not a gamer or a professional photographer, but I still can appreciate having crystal-clear resolution and stunning color for everything on my desktop.

4K on a 27" screen size is a very unfriendly resolution for Mac users

it's definitely worth the extra money for the improved resolution and improved connectivity

And the resolution of the LG is spectacular - wow-worthy

Even though the resolution isn't as good as the one sold by Apple, it's plenty good for me and has worked flawlessly for the past eight months.

Like many others, I decided to ignore this problem, even though I knew about it, because I wanted to see if it was all an exaggeration made up by some pedantic resolution freaks

I suspect many of the users of this monitor set the 'wrong' 2560x1440 resolution and then are unimpressed with the display's quality
