Question: 1 / 400

Which connection type is commonly used for monitors?

USB

HDMI

HDMI, or High-Definition Multimedia Interface, is commonly used for connecting monitors, as it can transmit both high-definition video and audio signals in a single cable. This versatility makes it a preferred choice for many modern displays, televisions, and multimedia devices. HDMI supports a range of video formats and allows for high-quality viewing experiences, including 4K and higher resolutions.

Other options, such as USB, while sometimes used for certain types of monitors (mainly for data transfer or as a power source), do not typically handle video signals the way HDMI does. Ethernet is primarily used for network connections, and Wi-Fi is a wireless protocol that does not directly connect displays but rather connects devices to the internet or local networks. Therefore, HDMI stands out as the most suitable and widely used connection type for monitors.
