Because it was originally based on the DVI standard, HDMI is backwards compatible with single-link Digital Visual Interface (DVI-D and DVI-I) signals. You can use this cable to connect a DVI-D/DVI-I output from your PC to display on your new big-screen HDTV (or vice versa). Ferrite cores are small magnetic blocks wrapped around the end of a cable. They are used to suppress EMI/RFI electronic noise on the cable by absorbing the unwanted high frequencies and dissipating them as very low-level heat. This is the simplest and cheapest form of electronic noise reduction and is most effective on small gauge cabling, which is inherently more susceptible to electronic noise interference than thicker cables.
This cable is functionally equivalent to a standard HDMI cable and supports all standard HDMI functions, except audio (DVI has no provision for audio). The specific
HDMI features support are: 1080i/720p resolution, Deep color, x. v. Color.
