How to connect an iPad Air 2 to a TV?

I recently bought an iPad Air 2 (my first iPad so it's all new to me), so I was wondering if it's possible to connect the iPad to a TV?

I've found a few cables that look like they'd do the job but I thought I'd get some advice before I spend my money - I'm not that fussed on getting apple TV though. It would be good if the sound as well as video came from the TV, rather than the iPad. This cable looked great but it has a connection for an older iPad model: http://store.apple.com/uk/product/MC748ZM/A/apple-composite-av-cable?fnode=3a

So I'm guessing I might need 2 cables? One for the video and another for the sound which goes from the headphone input to the TV?

Hope someone can shed some light on this. Thanks in advance,

Steve
