Hello Peter! Thank you for your question. I will be assisting you today.Yes, you would need a streaming device connecting to the TV. I recommend the Amazon Fire TV device; it's from Amazon, so it runs well with the Amazon Prime Instant Video app.http://www.amazon.co.uk/Amazon-CL1130-Fire-TV/dp/B00KQEJBSW/Thank you.
Many thanks. Just what I needed to know.
