Was wondering if anyone could help, I bought an Hdmi 1.2 extender last week off amazon and a couple of new cat6 cables. On receipt I hooked them up but when trying them from my free view box I was getting green dots all over the picture (on my ps3 I got no image at all). I made the possible mistake of not getting shielded cables, but I am only running 15m whereas they should be good for at least 30 on cat6. So, I sent that extender back and ordered another extender (looks exactly the same with the integrated Hdmi connector) but this one does v1.3. Unfortunately the exatc same symptoms though! So, are my network cables the problem or something else (they carry data ok)?
