i am having some issues with my hdmi connection... the first time i used it it was great! since then its has started not working some. now it isn't working at all... i had 3 tabs open and was streaming video on one and was loading video on the other 2 tabs..... the video was showing up but no sound... so in the past if i had multiple videos loading/streaming i have to find one that when i push play on then the others will work (sound wise) which was the case originally tonight... i then thought that maybe the hdmi cable wasnt connected all the way so i unhooked it then hooked it back in. the laptop screen goes black then back to the normal which i came to the conclusion means it acknowledges the output source. but the tv is saying no signal but it acknowledges there is something plugged in b/c the other hdmi sources on my tv (all 5) say that there is no device connected... so how and what do i do now since it is not connecting to my tv at all...any suggestions would be freaking awesome!
