Jezza,
I emailed LG Customer Service re: whether the inbuilt HD tuner in 32FS4D was genuine HD and this was their reply:
"Thankyou for emailing LG Electronics Australia. This TV does have a true HD tuner that receives HD broadcasts however the screen itself has a resolution of 852x576 which is SD so the picture is displayed at a maximum resolution of 576p. I hope this has been of some assistance. Thank you for emailing LG Electronics Australia."
This makes me think that I've bought a HD TV that can only display SD.
