Latest update...... I just zoomed off to Tesco and got a refund. I wasn't prepared to accept the poor performance for HDMI streaming, and I wasn't prepared to only have the very low resolution to stream.
No problems getting a refund. At least a well done on that Tesco.

Then off to Currys PC world to get an Apple TV....... easy set-up and top quality programmes to access.
Streaming from iPad to TV now automatic in HD with no issues. All wireless or by remote control.

Just exactly what the wife wanted.
