A second monitor can double your visible workspace. Most business laptops support at least one external display.

Connect and configure
- Plug the cable into the laptop and the monitor.
- Turn the monitor on — Windows detects it automatically.
- Press Windows + P to open the projection menu:
- Duplicate — same image on both screens.
- Extend — different content on each screen (recommended).
- Second screen only — use only the external monitor.
- To set which monitor is the main one: right-click the desktop → Display settings → drag the monitor boxes to match their physical layout → scroll down and tick Make this my main display.
Monitor shows "No signal"
- Try a different cable or port.
- Right-click desktop → Display settings → Detect to force Windows to look for new displays.
- Restart the laptop with the monitor already connected.
- Check that the monitor is set to the correct input source (HDMI 1, DP 1, etc.).
