I have dropped the refresh rate of the tv to 60 and turned off overscan. Since this post I have tried connecting my old monitor which never had an issue to the desktop and am having the same issue. Other things I've tried: checked, removed, reupdated drivers. Uninstalled/reinstalled the newest directx. Even went as far as to overclock the card to see if I noticed any difference. Nothing. Is it possible that connecting the pc through hdmi to the lcd-tv harmed the gpu? I'm pretty ignorant when it comes to hardware and what could potentially do harm.
