Hdmi is the newest association type found on all new contemporary Tv's, most contemporary Home Theatre amplifiers and many computer monitors. But why is it foremost to buy tool with Hdmi connections, and how much do you need to spend on Hdmi cables?
Hdmi stands for High Definition Multimedia Interface, and was designed to be a backwards-compatible replacement for the Dvi interface generally found on computer monitors. The standard called for a singular cable that could carry a high-definition video stream, up to eight channels of digital audio and a singular consumer Electronics operate Signal. Its customary purpose was to become the standard association between all consumer Av devices and computer displays. Today, all new projectors and televisions will come with at least one Hdmi association and usually more to receive hi-definition video.

Perhaps the most considerable part of the Hdmi specification is the keep for Hdcp, High-bandwidth Digital Copy Protection. Hdcp-protected content such as Blu-Ray movies can only be decoded by licensed Hdcp players, and any devices that connect to the player, must also be Hdcp certified, or the player will only production a standard-definition signal. For this reason, when buying high-definition projectors, televisions or other devices, it's best to make sure they have Hdmi connections and are Hdcp certified.
Be truthful when hooking up your home theatre system. It is not potential to have a Hdmi association to your amplifier, and then a component association to your projector, as the Hdcp protocol will prevent the player from sending a hi-def video signal due to the final association not being via Hdmi. It is possible, however, to connect your blu-ray player or cable box to your Tv by Hdmi and use a cut off connection, such as a digital optic cable, to send audio to your amplifier.
Hdmi carries both audio and video. This means only a singular cable is required to connect a Tv to your Blu-ray player or cable box. If you use a cut off Home Theatre amplifier, then the player and cable box can first be connected to the amplifier, which is then connected by other Hdmi cable to your Tv. In this setup, the amplifier uses the audio channels and passes the video channel on to the Tv. If you use the approach, look for a high-quality Home Theatre amplifier, with several Hdmi inputs for all your sources, which also keep Hdcp.
Finally, a few words on buying Hdmi cables. The prices of Hdmi cables can vary enormously, with determined branded cables costing 10x the price of the same length unbranded cable. In practice, Hdmi cable quality has very miniature impact on the quality of the audio and video transmitted through it. Unlike former home video cable standards, Hdmi is an all-digital connection, so the signals are much more defiant to interference and noise. For short cable lengths, practically any Hdmi cable will be fine. Longer lengths can be more susceptible to association dropouts due to Hdcp signal loss, so consider spending a miniature extra on these, but keep away from the most expensive brands as they offer very miniature extra benefit.
