Arrangement tab is not showing System Preferences -->Display option

What USB-C cable, EXACTLY?

If this is the default white cable shipped with your Mac, that is is Charge-ONLY cable, suitable ONLY for charging and possibly running a keyboard, as it has NO high speed data pathways.

Hi lino837,

We understand you're having trouble connecting an external monitor to your computer. We're happy to help.

To get started, how are you connecting this monitor to the computer? Is it using an HDMI cable, USB-C cable, or Thunderbolt cable?

In the meantime here's some basic steps for setting up an external monitor that may help: Use external monitors with your Mac

We look forward to your response. Cheers!

Hi lino837,

So you're using a USB-C monitor connected with a USB-C cable. Thanks for confirming!

If you have any other USB-C cables, we'd recommend trying that to rule out any issues with the current one you have connected. You'll also want to make sure the USB-C cable is connected directly to the monitor on one end and directly to the computer on the other end. If you have any sort of USB hub attached to the computer that the cable is connected to, the computer won't recognize the monitor.

Here's some additional steps you can try for issues with the computer recognizing the monitor: Get help with video issues on external displays connected to your Mac

If you continue to have issues with the computer recognizing the monitor, you'd want to contact Apple Support directly for assistance: Get Support

We hope this helps. Take care!

The arrangement tab can only appear AFTER the display is recognized. Before that, there is nothing to Arrange, so that pane remains hidden.

Not seeing that pane is a SYMPTOM of non-recognition.
