Hi, here are my specs

i5 3570k
asus p8z77-v lk mobo
8gb kingston hyperx ram
gtx 680 2gb
cx600 psu

i am currently using a vga connection to my monitor but want to switch to hdmi so i can hook my pc up to my tv for some couch style games, plus it seems that some ghost static style lines have appeared on my screen, they are most visable on black/grey parts of the screen.

Unfortunately whenever i try to use the hdmi port from my graphics card i get no signal, i have tried several displays now and nothing, im stumped, any help?
