Great Addition to Mac miniPurchased 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.

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.

Owner's manual states "Vertical orientation is not recommended." 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.
