What people are saying

Rated 5 out of 5 by from Crisp text and single cable connection I've been using this for about 2 years. The 5k resolution displays crisp text which is easy on the eyes while coding all day. Just a single Thunderbolt cable connects the monitor to the MacBook both charging the MacBook and acting as a USB hub.

Rated 1 out of 5 by from Terrible Customer Service I bought the monitor eight months ago and it suddenly went black. I went through all the troubleshooting and was eventually told to ship the monitor back to LG. Getting a hold of any live human who speaks clear English or who had any compassion was not possible. My experience will make me think twice before buying another LG product.

The listing for this device on woot.com says: &ldquo;The display might not turn on until you boot into macOS&hellip;pre-boot features such as Boot Picker and macOS Recovery might not be available on the display.&rdquo; Is this true? Can it be the only display on a Mac mini?
