How to Extend Your Screen on Windows: Step-by-Step Guide for Dual Monitor Setup
Extending your screen isn’t just about having more pixels—it’s about boosting productivity, improving workflow, and enhancing entertainment. Whether you're a remote worker juggling apps, a designer needing extra space, or a gamer looking for immersive play, learning how to extend your screen is a simple way to unlock your computer’s full potential.
1. What Does It Mean to Extend Your Screen?
Extending your screen means using two or more monitors to expand your desktop workspace. Instead of duplicating the same display on both screens, extended mode allows each monitor to show different content—perfect for multitasking or immersive work setups.
2. How to Extend Your Screen on Windows
On Windows 10 and Windows 11:
Step 1: Connect Your Second Display
- Plug in your external monitor via HDMI, DisplayPort, USB-C, or VGA.
- For laptops with limited ports, devices like the Cevaton P5 Portable Dual Monitor Extender or Cevaton S6 Triple Screen Extender can easily add one or two displays through a single USB-C port.
Step 2: Open Display Settings
- Right-click on the desktop and select “Display settings”.
- Or press Windows Key + P and choose your projection mode.
Step 3: Select “Extend These Displays”
- Scroll to the “Multiple Displays” section.
- From the drop-down menu, choose “Extend these displays”.
- Drag and arrange display icons to match your physical setup.
Step 4: Confirm and Apply
- Click “Identify” to confirm which screen is which.
- Adjust resolution or orientation if necessary.
- Click “Apply” and then “Keep changes” to confirm.
