So I was looking at HDMI cables for my cable TV and Xbox and noticed one cable from Phillips said just "Hdmi". The next cable said "High speed HDMI 1.3a". Both were the same price for the same length, and you know you usually pay more for better. So it looks like the 1.3a can send data faster, and I read it can do "deep color" (basically just better than RGB?). But is it possibly worth anything in my situation? If not, go ahead and get the 1.3a (assuming it's compatible with what I got)?
