Thank you all for the input. I have discovered that Most if not all Sony TVs allow you to turn off overscan on 1080i/p signals.

Nice review here: http://www.dvdtimes.co.uk/content.php?contentid=63698

The HFX that Bruno linked to looks nice. But it looks expensive! I'll need to take a further look at it.

One last query though...

A pc outputting video on DVI/HDMI - is this 1080p or 1080i? Does tthat even make any sense?
