I use this type of cable to send component video from high definition video sources into a Hitachi pma400e plasma's unused 2 x pc inputs, as it has no hdmi and only 1 x component input. This gives me 3 x component inputs.
Firstly I spent considerably more than this on a Ixos hd15, so when I needed another I decided to try one of these.
It produces the same results as the Ixos, flawless 1080i hd video.
Note you will also need a mini rca to 2 x rca cable like 3.5mm Jack to 2 x RCA Phono Stereo Audio Cable 3m Lead
Bear in mind this is merely a passive video only transmission cable, it does not 'convert' anything, so it is important you thoroughly understand what your equipment can or cannot input/output before purchasing.
For example (in my experience) Hitachi and Sharp flat panels generally accept component over vga, Panasonic and Samsung do not. Check your manual or menus to be sure.
It was a shame the other reviewer marked it down because he didn't read the (quite detailed) product description which clearly stated 'vga card necessary'.
Overall an excellent value cable with many different uses.
