HDMI Cables are probably the best way to connect modern LED, LCD and Plasma TVs. Through it's incredible speeds of upto 10.2Gb's in a single HDMI Cable, it delivers High Definition Pictures and the best Surround Sound around. It also can now supports 3D, Higher Resolutions (2k4k) and ARC (Audio Return Channel - your tv send the sound back to your hifi). HDMI and HDMI cables offer amazing functionality at a very low cost.
ARC : Audio Return Channel - If you play all of your surround sound via your HiFi, then you'll have your BluRay Player, Sky box, PS3 etc plugged into your hifi and your hifi connecting to your TV, all with HDMI. The problem lies that if you're watching Freeview built into your TV, you'll only be hearing it on your TV speakers. ARC allows you to send the sound to the Hifi from the TV (audio return) and you can benefit from surround sound even on standard Freeview programs. Both TV and HiFi have to support ARC and the cable must support ARC too.
