How many hdmi inputs do I need?
Depends on how many devices you’re going to have. I always say the more, the merrier, but it’s easy enough to buy a HDMI switch if you do run out. I bought one from a company online for $35: www.monoprice.com It’s got 4 inputs and a remote. I wish it was auto-sensing though, but it’s good enough and way cheaper than the ones I’ve seen in stores.
