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)!Silver-plated conductors provide improved signal conductivity over normal copper wires. When signals are transmitted at frequencies in the MHz range, very little of the signal actually penetrates to the core of the conductor. Most of it simply rides along the outside of the wire in what is known as the skin effect. Silver is a better conductor than copper, but is of course too expensive to use for an entire conductor. However, a thin coating of silver on the outside of a conductor takes advantage of the skin effect by providing higher conductivity where the signal will actually be carried.In cases where the length of a cable may be approaching or just beyond the distance for a reliable HDMI� signal transmission, often characterized by an intermittent breakup or interruption in audio or video portions of the signal, a silver-plated cable can provide the extra level of conductivity to ensure a reliable HDMI� connection between the source and sink (display) devices.The CL2 rating on this cable indicates that it complies with fire safety codes and insurance requirements, making it safe for use inside the walls of residential class buildings.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*** 30-day easy returns. No restocking fee. Free lifetime technical support. Limited lifetime warranty. ***
