Which device would typically be connected using a VGA connector?

A VGA connector is commonly used for transmitting video signals from a computer to a display device. Among the options provided, a projector is the most appropriate choice, as it often requires a VGA connection to receive video output from computers or other devices. Projectors use VGA to relay images and videos effectively, especially in presentations or educational settings.

Televisions may have multiple connection options, including HDMI and composite inputs, and while some older TVs might support VGA, it is not standard for modern models. A USB hub is intended for connecting multiple USB devices to a computer and does not utilize a VGA connector. Headphones are audio devices that connect typically via a headphone jack or USB, completely separate from video connections. Thus, projectors are the primary devices that typically utilize VGA connectors.
