Ok so here's the thing, i've got my Xbox One connected to my A/V amp via HDMI then i've connected the TV to the amp via HDMI, my problem is that after the xbox has been on a while i seem to get a little bit of picture interference in the form of white dots on the screen, a bit like the snow interference you used to get but smaller dots and a lot less of them, but still there, my question is could the cable be causing the interference, it was a cheap one off eBay so might not be the best quality.
