HDMI OUT: Everything You Need to Know About This Interface

In today’s digital display ecosystem, HDMI OUT plays a crucial role in connecting display devices to external screens, projectors, video walls, and audio systems. While HDMI IN allows your display to receive signals, HDMI OUT transmits audio and video signals from your device to other displays, making it essential for presentations, digital signage distribution, and multi-screen setups.

At Qtenboard, all our interactive whiteboards, LCD videowalls, kiosks, StandbyMe TVs, and digital signage products come equipped with HDMI OUT ports, enabling businesses, educational institutions, and retail environments to broadcast high-quality content seamlessly. This article will provide a detailed guide on HDMI OUT, including its uses, types, benefits, and practical applications.

An HDMI OUT port has the same rectangular shape with 19 pins as HDMI IN. Depending on the device, the port can be:

• Type-A HDMI OUT: Standard full-size port for TVs, monitors, and videowalls
• Type-C HDMI OUT: Mini HDMI port for laptops and portable devices
• Type-D HDMI OUT: Micro HDMI port for mobile devices and compact cameras

On devices like Qtenboard interactive whiteboards and videowalls, HDMI OUT ports are usually labeled “HDMI OUT 1”, “HDMI OUT 2”, allowing users to connect multiple external displays simultaneously.

HDMI OUT ports are essential for transmitting audio and video to external devices. Common applications include:

• Presentations: Connecting a laptop or whiteboard to a projector or monitor in classrooms and conference rooms
• Digital Signage: Sending content from a media player or video controller to one or more displays
• Video Walls: Outputting synchronized content from a video wall controller to multiple screens
• AV Systems: Sending audio and video to sound systems, projectors, or TVs

For example, in a business conference room, a Qtenboard interactive whiteboard with HDMI OUT can transmit the instructor’s or presenter’s content to a secondary display or projector, ensuring visibility to all participants. In retail, HDMI OUT can broadcast promotional videos across multiple screens at once.
