Apple Intelligence is now available on iPhone, iPad, and Mac!
Hi,
I recently bought a LG 24-inch UltraFine 4K USB-C Display. I want to connect my 2017 Macbook Air to this monitor.
My Macbook air only has thunderbolt 2 (mini displayport), so the included USB-C cable does not suffice.
What cable(s) do I need in order to properly connect them?
Kind regards
MacBook Air 13", macOS 10.15
If the display is USB-C only (no lightning bolt icon next to any USB-C port), you can't use it, but if it's the LG UltraFine 4K Display sold by Apple

it also supports Thunderbolt 3 on two of its USB-C ports. Connect a Thunderbolt 3 adapter

to one of those ports and connect a Thunderbolt cable

from the adapter to the computer.

About the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter - Apple Support
"This adapter is bidirectional, which means you can use it to connect Thunderbolt 3 devices to a Mac that has a Thunderbolt or Thunderbolt 2 port."
It is indeed the lg monitor sold by apple.
I am concerned about the thunderbolt 3 to thunderbolt 2 cable.
I believe that the thunderbolt cable will transfer my MacBook data both ways.
But does the data also flow both ways in the thunderbolt-3-to-thunderbolt-2-adapter?
So if I connect this thunderbolt cable which is plugged in my MacBook Air to the thunderbolt-3-to-thunderbolt-2-adapter which is plugged into this monitor, it will result in my MacBook Air screen being shown on the lg monitor?
Thank you in advance
You can also charge the MacBook Air from the display's second Thunderebolt 3/USB-C port with a USB0C to Magsafe cable.
