I believe I'm not using the proper cable connected from the my large Apple monitor to my Macbook. Do I use the port on the back of the monitor that has the lightning icon to connect the two? And what kind of cable should I be using.
I rarely disconnect everything because of this issue.
MacBook Pro 14″, macOS 15.6
exactly what model-year MacBook Pro 14-in, and processor type {(plain), PRO, MAX, ULTRA} ??
Identify your MacBook Pro model - Apple Support
What model Apple display?
many Apple devices have their model numbers silkscreened in a nearly-hidden place with light gray ink. If not found, just post what you know, like diagonal size of display.
Please don't post any serial numbers, they attract vermin.
You use the TB port (lightning symbol) to connect to your Mac if your Mac has TB ports. Always use a TB cable.
External monitor showed three dots and then went black when connected to power.
