I have my pc connected to my HDTV via a very good HDMI cable. Everything works fine except when I turn off the TV and pc. When I turn the pc back on nothing works right. Is there some kind of setting I have to use? Why doesn't the pc turn on correctly. So far I have to unplug the HDMI cable from the pc in order to get the pc to run at all and that is after several manual on and off's on the CPU. Any suggestions?
