6. Mirror and Extend Modes

The dongle supports two primary display modes:

• Mirror Mode: Duplicates your device's screen onto the larger display. This is ideal for sharing presentations, photos, or videos directly.
• Extend Mode: Allows the larger display to act as a secondary monitor, extending your desktop. This enables you to work on different applications simultaneously on your device and the external display, maintaining privacy on your primary screen.
