Step 3: Connect and Set Up

Windows

1. Plug in both monitors and switch them on.
2. Press Windows + P and pick Extend.
3. Open Settings → System → Display, click Identify and drag the screens to match their positions on your desk.
4. Set each screen's resolution and scale; choose your main display.

Mac

Open System Settings → Displays and arrange the screens. Some MacBooks, including base M1 and M2 MacBook Air models, support only one external monitor natively; check your model's specifications.

Only One HDMI Port?

• Use the HDMI port for one monitor and a video-capable USB-C port for the other.
• Use a dock or hub with two video outputs (check that your laptop supports multiple screens through it).
• Use a DisplayLink USB adapter (needs a driver).
• A splitter like the HDMI 4-way splitter is for showing the same picture on many screens, such as shop displays or classrooms.

Which Laptops Work Well?

Business laptops such as HP EliteBooks often have both HDMI and USB-C or DisplayPort. Browse refurbished laptop prices and check ports in the product details.

Common Mistakes to Avoid

• Buying a splitter to extend the desktop.
• Assuming every USB-C port carries video.
• Using a long, cheap cable for a 4K screen.
• Not arranging displays in settings, so the mouse jumps the wrong way.
