Just as several advances have taken place in the realms of processor speeds, memory, display resolution and clarity, so have similar improvements bee made in how the various components of a computer connect to each other. From serial cables that were originally used to connect monitors and and printers to the CPU, now there exist USB connections and infared connectivity. USB in particular is what most PC manufacturers have long hoped will become the standard for all component connectivity, thereby minimizing the number and variety of inputs required on the typical body or chassis of a computer. With only a single, or at most two primary input technologies used by component and accessory manufacturers, then PC makers need only build their machines to satisfy these modalities while conserving precious space and money during their PC build-outs.
One particular interface that has grown in popularity since late 2003 is HDMI (High-Definition Multimedia Interface). This technology has coupled high definition audio and video connectivity from PC to Monitor in one cable. No longer do computer users require two separate cables, one for their monitor and one for their speakers. This not only conserves valuable space on the computer chassis, but also takes away the need for separate video and sound card slots inside the computer, without sacrificing high-definition capability of both. A single HDMI cable supports standard, enhanced and HD video as well as 8 channels of compressed or uncompressed digital audio.
Finally, HDMI is by no means limited to only PC applications. As a matter of fact, this interface is designed to transmit HD audio and video data from most audio/video sources such as video game consoles, DVD players, PCs and AV receivers to digital audio devices such as digital televisions and computer monitors. HDMI provides a solution that has obtained industry wide acceptance for digital connectivity between your computer and your television.
