What people are saying

Rated 4 out of 5 by from Great Addition to Mac mini Purchased to accompany a new Mac Mini in May 2021. The screen quality is EXCELLENT. The monitor connects to the Mac easily using the the Thunderbolt/USB4 wire. No syncing and set up necessary. My only issue has been that the screen went Black 2 times. LG customer service quickly sent out two new cables. A new power cable and a new Thunderbolt/USB4 cable. The new cables arrived and I was back in business. Out of curiosity I tried switching out the old cables, one at a time, to identify which cable had gone bad. Appears that my Monitor is working with the old cables as well... next step is to have the Monitor looked at.

Rated 5 out of 5 by from Quite possibly the best Mac monitor… The 24MD4KL-B is quite possible the best choice in a monitor for your Mac ( only exception being Apple’s own $6k display). This 4K display is designed for your Mac and hooks up quickly and easily with the included Thunderbolt 3 cable. A cadre of USB-C ports lets you hook up all of your other legacy devices directly to the monitor and have a single Thunderbolt 3 cable to connect/power your MacBook Pro. Talk about plain and simple - It just works - no software drivers needed - plug it in and enjoy the stunning 4K display. To go mobile, just unplug the single Thunderbolt 3 cable. Exceptional price, clarity, brightness, and color quality are the hallmarks of this display. If you have limited physical space, but need the real estate of a high-end 4K display, then this is the monitor for you.

Rated 5 out of 5 by from Best Monitor! I purchased this monitor for use with a new Mac Mini. I couldn’t be happier with my monitor purchase. Easy thunderbolt connection and the picture quality is amazing.

Owner's manual states &quot;Vertical orientation is not recommended.&quot; If this egregious limitation is excess heat-related in this monitor model, of what use is the internal fan if not to promote ventilation of excess heat, regardless of the orientation?

Is it possible to connect a Thunderbolt to Gigabit-Ethernet Adapter to in the monitor and than at the same time a macbook pro to the monitor and obtain an internet connection. If yes does the download or upload speed changes

Asked by: DaveWo
Yes, I have a Satechi USB-C multi-port adapter with Ethernet adapter that supports GB Ethernet attached to one of the USB-C outputs on my LG Ultrafine 5K montor. I have not tested the Ethernet throughput though the Ethernet is communicated through the Thunderbolt and out the USB-C hub.

I purchased 2 of the new 24&quot; LG UltraFine 4K monitors, I have them installed side by side, the one of the left the whites look more &quot;blueish&quot; and the one of the right has &quot;warmer&quot; whites, what is the best way to calibrate the colors on both of them.
