RGB (Red, Green, Blue) is an analog video signal format commonly used in older computer and video devices, while HDMI (High-Definition Multimedia Interface) is a digital video and audio interface standard used in modern TVs, monitors, and other devices. Connecting an RGB device to an HDMI display requires a converter to translate the analog RGB signal into a digital HDMI signal. This article provides a comprehensive guide to RGB to HDMI converters, discussing their features, benefits, and how to choose the right converter for your needs.
RGB signals are composed of three separate channels: red, green, and blue. Each channel carries a voltage level that corresponds to the intensity of the respective color in the image. RGB signals are typically carried over three separate wires (one for each channel) and are commonly used in legacy computer systems, such as VGA and DVI.
HDMI is a digital interface that combines video and audio signals into a single cable. HDMI signals are transmitted digitally, providing higher quality and resolution than analog RGB signals. HDMI supports a wide range of resolutions, including 4K and 8K, and can transmit multi-channel audio formats, such as Dolby TrueHD and DTS-HD Master Audio.
