Hello MJG_65,

Connect a display to your Mac
Mac computers support one or more external displays, depending on the Mac model. Here's how to connect an external display.
Connect the display to power and your Mac
1. Use your display's power cable to connect the display to power.
2. Use your display's video cable to connect the display to your Mac, such as to a Thunderboltor HDMI port. Different ports might look similar, so it's important to identify the port correctly.
3. If the video cable requires a port that your Mac doesn't have, you might be able to use an adapter with the video cable. Or replace the video cable with one that doesn't require an adapter.
4. When your display has power and is connected properly, your Mac detects the display automatically. You should then see your Mac desktop on the display, and you can configure display settings.
If your display isn't detected or can't use its highest resolutions or refresh rates, learn what to do if your display has a dark screen (no video) or low resolution.
Configure display settings
* From the Apple menu in the corner of the screen, choose System Settings (or System Preferences), then click Displays. In display settings you can change display resolution, choose a refresh rate, arrange your displays, and more.
* If the display is not made by Apple, certain settings might be available only by using the display's built-in controls and menu system. Check your display's documentation for details.

* Use an iPad as a second display for Mac
* Use AirPlay to stream what's on your Mac to an HDTV
* Connect to 8K displays, or to 4K displays with high refresh rates.
* Connect to HDMI displays
In case that doesn't resolve your issue, please reply back with more information about the display and connections. For example, what ports are available on the display? Have you tested other cables and adapters? Let us know, so we're on the same page.
Take care.
