How To Setup Multiple Monitors in Virtualbox

Описание: Want to use multiple monitors with your VirtualBox virtual machine? This quick tutorial shows you how to set up dual or multiple screens for any guest OS (Windows, Linux, etc.) using VirtualBox’s Display settings. Perfect for developers, testers, or anyone needing a multi-monitor VM setup. Get your virtual desktop extended in minutes!

Method: Configure Multiple Monitors in Display Settings
Ensure your VM is powered off. In VirtualBox, select your virtual OS and click Settings → Display → Screen tab. Set Monitor Count to 2 or higher (e.g., 2 for dual monitors). Increase Video Memory (e.g., 128MB) if prompted. Install Guest Additions (Devices → Insert Guest Additions CD Image) if not already done. Start the VM. Once running, go to View → Virtual Screen 2 (or higher) → Enable to activate additional screens. In the guest OS, use display settings to extend the desktop across monitors.

Why This Happens
VirtualBox defaults to a single virtual monitor to save resources. Setting a higher monitor count and enabling screens allows the guest OS to mimic a multi-monitor setup, boosting productivity.

Conclusion
Your VM should now support multiple monitors! If screens don’t appear, ensure Guest Additions are installed and the VM is in windowed mode. Drop questions in the comments, and we’ll help you out. Like, subscribe, and hit the bell icon for more VirtualBox tips!
