Edges of the picture?
What does:
"...and there was a good level of detail and definition right out to the edges of the picture." mean?
This isn't a photographic lens or digital camera review. How can a digital video playback system exhibit a lack of sharpness at the picture edges?
Either a lack of edge definition would be related to the camera and production processes or the display (if it was a raster scanned CRT).
Both of these are outside the scope of this article and display a lack of technical knowledge by the reviewer. It also smacks a little of audio reviewers whining on about breadth of soundstage, etc.
Meaningless, like comparing colour 'liveliness' from an HDMI source.
