Let's walk through the steps to set up a second display when using Windows 10. We'll cover the basics of getting your second (or third) display set up and customized to your liking. First, start by plugging in your extra displays and make sure they're powered on.
Connect to an External Display
Press the Windows key and the letter P (WIN + P) on your keyboard. This will reveal a side panel where you can select your screen configuration:
Here's a quick explanation of your options:
- PC Screen Only- Only your primary display will be enabled; all secondary screens, monitors, and projectors will be dark. This can be useful if you're presenting and you don't want participants to be able to see your screen.
- Duplicate- Your primary and secondary screens will mirror one another, displaying the same thing. This can be useful for presentations or for demonstrating.
- Extend- This setting extends your desktop across all of the displays you have enabled. If you're using a second monitor on your desk, this is probably the setting you want to use.
- Second Screen Only- This will keep your primary display while only using your scondary display. This is useful if you have a closed laptop attached to a docking station, since you don't want Windows to use your laptop's screen.
2. In the basic systems preference pane, you can drag the screens around to orient them to how your monitors are arranged. If you need to identify which screen is which (they're only identified with numbers), click on 'Identify' and each screen will display its designated number. You can also change the brightness and the magnification level.
3. To change the displays' resolution, color settings, and other advanced features, click on 'Advanced display settings' at the bottom of the display settings preference pane.
How about Three Screens?
It's pretty much the same deal. If you have a laptop, desktop, or docking station that will support two additional screens, you can re-arrange and configure them using the Display Settings preference pane:
