This sums up the HD TV situation - many have so called HD TV's but no HD input.

A lot of modern TVs have built in freesat so a set-top box in not a necessity for HD. Admittedly there's not a lot of HD material as yet, but it's possible to recieve HD without a set-top box.

Extract from the above link

"It then revealed, however, that almost half of those who believed they were watching in HD had not actually connected the necessary player or set-top box."

The thread title actually sums up the cause of this confusion.

In the vast majority of cases they are HD Ready TVs, not HD TVs.

Most HDTV's have some way of displaying the resolution of input signals. On my Samsung HDTV you press the Information button on the remote. This then shows, amongst other things, the screen resolution of the incoming signal. If it's just SDTV then no resolution is shown, 720p HD resolution shows as 1280*800 and 1080i HD shows as 1920*1080.

If you are connected by a SCART cable then you cannot be viewing as HD as SCART only supports SDTV.

HDMI supports 576, 720p and 1080i and 1080p. 576 is SD and the other three are HD. 720p shows the screen as one complete image whereas 1080i interlaces 2 images of half screen resolution to produce one complete image. 720p is theoretically better for fast action subjects but in my experience theirs little to chose between 720p and 1080i when viewed at home.

1080p isn't available from broadcast TV. It's essentially a Blu-ray format. DVD is 576p.
