I have the MSI's MS7368 motherboard which has the hdmi jack,but when I connect it to the TV I don't get a signal? b)then when I connect thru my video card using DVI to hdmi adapter and then connect to hdmi on tv I don't get any sound? can someone help explain why on both accounts?I don't understand why from the pc using hdmi direct to the hdtv does not get a signal? Is there some other device that I need in order to connect my pc to my hdtv using hdmi.the tv is a magnavox 27"in. lcd flat screen 1080p capable,it has two hdmi jacks a, 9 pin serial connector for a monitor/w-separate audio jack for the pc but it also has hdmi so why can't i get a signal using the hdmi cable from the onboard hdmi jack to the tv direct?
