So I bought my MacBook a year ago and I just bought cords for my laptop to my TV. I bought a Mini DisplayPort to DVI cord than an Xtreme HD cord thats DVI to HDMI. For some reason however I can't get the sound to play off of my TV no matter what, it only plays on my laptop and I was told it would be able to just fine, however for me thats not the case. Second when I link the two screens up together my TV will just have the Background no icon's or anything just the plain simple background. Once I click "Mirror Screens" then my laptop screen is completely small for me and my TV one is just fine, but when I open applications b/c my laptop screen is so small like the "Play" button for movies is nearly impossible to hit because its right behind the dock. So my questions are: How do I get sound out of my Mini DisplayPort to DVI & DVI to HDMI cord instead of buying an audio cord from laptop to TV. How can I mirror screens correctly to keep the same size on my laptop screen for when I open things they aren't smushed or hard to play. Finally my buddy has a Windows PC and he can close his Windows PC and be able to still use it on his TV, when I close my MacBook it closes out on the TV, how can I keep them simultaneously running?
