What people are saying

Rated 5 out of 5 by from Excellent monitor! I bought this monitor about one month ago and love it! It works seamlessly with my MacBook Pro and you can choose to download the app but not really needed. The only thing I would improve is the video camera. Fortunately I have a better camera already so I use it instead of the one built in monitor. Speakers are fine but the screen image quality is excellent! I highly recommend purchasing if you can afford it.

Rated 1 out of 5 by from Great when it works. Screen keeps flickering I bought this a few months ago from FB Marketplace, and for the first few months it was great. Picture quality was amazing and overall was very happy. However, more recently there have been a lot of problems with screen flickering. Whenever I'm connected, it will just randomly black out and it's unclear why it's happening. Would love to get some support from LG on a fix here (I believe online there are a lot of other cases of this happening
