I bought this from Verizon and tried it today. It didn't work! No video or audio. I confirmed input and reconnected the cable more than once. I tried to look through the menus to make sure it didn't need to be directed to output over the cable...nothing there either. The box says it is for the Galaxy Tab (not 10.1) but VZW's website listed it as for the 10.1. Anyone know what the deal is? Is it a bad cable or does it just not work with the 10.1?
