The HY320 Mini Smart Projector can be a flexible display option when used with compatible external devices. Depending on the exact model, supported connections may include HDMI or USB, allowing users to connect selected laptops, media players, storage devices, or other equipment. These connections can expand the projector's usefulness beyond built-in smart applications. For example, a laptop can provide presentation content, while a compatible media player can supply video entertainment. Users should verify which ports are available and whether a particular device is supported before connecting it. Selecting the correct cable and input source helps avoid setup problems and makes switching between entertainment and productivity tasks more convenient.
