I have my PC running an amd hd 7750 connected to my element ELEFW264 TV via hdmi. The picture shows up, but the screen looks all grainy and weird. I used to use VGA with the same computer and TV and it was perfect, but i got a new monitor that needs the VGA port. I tried to fix this problem a while back but i couldnt seem to find out what the problem was. Any help is appreciated.
