I was wondering if someone could give me a hand here? I am looking to do the wall mount for my TV the model is LC-37G4U from Sharp. The only thing is the Sharp wants almost $500 for the long system cable and I will be damned if I am going to pay that much for the cable. I was looking at the system and it appears that the cables inputs are all standard dvi/vga/s-video. Does anyone have experience with this? And is this the case?
