Hello. Recently I have tried connecting my hdmi cables from my pc to my tv, yet nothing comes up on my tv. Yesterday I received a new motherboard (asus sabertooth z87) after an RMA process and have just completed building my pc and everything works including the dvi port from my graphics card to my monitor, so I don't believe it is a graphics card issue. I also tried the hdmi port from my motherboard and still nothing. Is there something I am missing? thanks for any replies.
