After successful driver installation, you can configure your display settings through your operating system's display properties or the Matrox PowerDesk software (if installed).

3.2. DualHead Functionality
The Matrox G450's DualHead feature allows you to use two monitors simultaneously. This can be configured in two primary modes:

- Cloned Display: This mode duplicates the content of your primary monitor onto the secondary monitor. This is useful for presentations or sharing your screen with an audience.
Access these settings through your operating system's display settings (e.g., right-click on desktop > Screen Resolution in Windows) or the Matrox display utility.
