Yes, there's no Arrangement tab unless there's an external display connected. All Mac notebooks support at least one external display at some resolution. How many and at what resolution depends on your model of Mac.

Thanks for the quick reply, I just figured out what the problem was. I was just trying to check if my laptop supported an external display, but it wasn't connected to the monitor because I'm still waiting for the adapter to come in.
I'm trying to connect a TV as my external monitor using a USB to HDMI adaptor and then an HDMI cable. I've installed the adaptor's drivers, however, but a signal doesn't seem to be sending in order to activate the Arrangements tab to appear. Any suggestions?
to get a Mac display to become active, you need the Mac to query the display, and the display to answer with its name and capabilities. Otherwise, the display will not be shown as present, and no data will be sent to the display.
This query is only sent at certain times:
• at startup
• at wake from sleep
• at insertion of the Mac-end of the display-cable, provided everything on that cable is ready-to-go
• on invoking Option-(Detect Display) button in Displays preferences (from another display)
so try doing some of those things and see if the display comes alive.
Modern Displays with multiple ports are sometimes busy scanning the other ports, looking for an input, and miss the query from the Mac. They need to pay attention to the port you are actually using, or they will miss the query.
Some displays have On-Screen Display settings that can be used to tell the display a computer is attached on a certain port, or a certain port should be highest priority. Changing those may make your display more responsive.
Some displays include their own private "sleep" settings for the display alone. This can allow the display to enter its own sleep mode, on top of the Mac's not sending it data. A display that is sleeping on its own cannot respond to the Mac's query, and will stay dark.
Does a desktop show on the external display(s)? How many displays, what Mac (model, display size and year), and how are the display(s) connected?
