Rated 5 out of 5 by from Great! I was looking for a monitor for video editing and this was recommended to me. I’ve had it for about a month now and it’s great!

Rated 5 out of 5 by from Great Productivity Monitor - MacBook Pro 16 (M1) I wanted a monitor that could handle side-by-side documents. Has USB-C and HDMI which both work well with the 2021 MacBook Pro (M1) 16 inch. Use of the USB-C will charge the MacBook (as well as a work Dell Laptop) - and a mouse I hooked up to the monitor worked fine. Text was very readable, videos were also good. I don't play any computer games. Refresh rate was 60 Hz (I believe - for both the MacBook and Dell). Also adjustable in height. I could pretty much fit my MacBook 16 inch under the monitor when it is set to the highest height (need to angle the MacBook slightly for a perfect fit). Great price for the quality and features.

Rated 1 out of 5 by from Returning it. Very dissapointed. After only a few hours out of the box, it started to show a black shadow on the right side of the screen. Next morning: another black shadow but right in the middle of the screen. Don't buy this if you actually need a working monitor.

Will this work with a 2017 Macbook Pro?

Asked by: Gill32
Yes. Tested and working with a 2014 and 2019 MBP (the latter with HDMI dongle). It doesn't appear to work over USB-C with the later model though.

Does this monitor have PIP, SBS picture?

For a monitor at this price it should, but disappointingly doesn't. A real missed opportunity here LG.

Does OnScreen Control work with Misson Control for Mac? Specifically, if you have multiple desktops open in Mission Control, can each desktop be configured differently in OnScreen Control?

Asked by: macaddict
No, screen split (basically rearranges your app windows) is a global setting, not per-desktop.
