HDMI ARC output, 2 HDMI inputs, optical in, and USB. It's hard to find so many HDMI connections, even just one, on a well-known brand at this price. Has good reviews on Amazon where it's £109 from a seller with a dodgy name and £149 from Amazon themselves. Most other places it's £120+ so for the £89 from the Tesco Outlet store on ebay seems like a really good deal. Oh, and it's brand new with a 12 month warranty. More than 10 in stock at the time of writing.
