It uses the same underlying protocol as the DVI digital signal, so it can also be interchangeable with the DVI signal through an adapter and is compatible with the DVI signal. More powerful than the DVI interface, HDMI allows the transmission of high-fidelity audio signals through HDMI cables when formulating communication protocols, and seamless connection reduces the trouble of wiring, and also allows HDMI to have a wider compatibility. It supports 5Gbps data transfer rate and can transmit up to 15 meters.

Compared to DVI, HDMI can transmit digital audio signals and adds support for HDCP while providing better DDC optional features. HDMI supports a data transfer rate of 5Gbps and can transmit up to 15 meters, which is enough for a 1080p video and an 8-channel audio signal. And because a 1080p video and an 8-channel audio signal require less than 4GB/s, HDMI has a lot of headroom. This allows it to connect DVD players, receivers, and PRRs separately with a single cable. In addition, HDMI supports EDID and DDC2B, so devices with HDMI have the characteristics of "plug and play", and the signal source and display device will automatically "negotiate" to automatically select the most suitable video/audio format. Coptic Electronics has to do HDMI to DVI cables.
