"Hit the mark"

Bought to connect my PS3 with my 2 television, which is about 7 meters cable. I have to say here really is true, who buys cheap, buys twice. Absolutely no picture or sound to plug it on PS3 / TV. The screen remained black. Thought I have incorrect settings on the Playsi have, therefore asked tentatively the television next to the PS3 and connected to an Amazon High Speed ​​HDMI cable of 2 meters in length, here the picture was knotless, pity the Amazon but offers these cables only up to 3 meters , will have his reasons :-)
Either the cable was defective or can not handle the distance ...
