Thanks guys will try those later!
When the engineer arrived he amused me quite a bit, firstly by calling it a 'HMDI box' and then uttering 'not that I know how to install it'. After him refusing to put it upstairs due the fact that 'in the meeting we were told to only put them downstairs'. I explained I didn't want it installed in my downstairs neighbour living room we managed to get it up and running as I had all the leads already connected TV side.
The set up was then done on his mobile as instructed by his TL. It was kinda fun getting involved, and then him sitting down to watch 'how good and clear the picture is'. I am on the edge of technology here
