Can anyone tell me what the difference is please? And is one better than the other?

Thanks

You want full HD 1080P NOT 1080i.

'HD Ready' means that the TV will accept a standard Digital HD signal from FreeView, Virgin or Skydigital, which currently transmit in 720p (or 1080i) and while you can play Blu-Ray movies on them, and they will look better than normal DVD's, its not the full detail.

'Full HD' means that its 1080p, these still accept the 720p and 1080i signals, but will offer the full range of details from 1080p blu-ray (and other) sources...

For a full explination on the differences, see the following...
Main: http://en.wikipedia.org/wiki/HD_ready
HD TV: http://en.wikipedia.org/wiki/High-definition_television
720p: http://en.wikipedia.org/wiki/720p
1080p http://en.wikipedia.org/wiki/1080p

Thanks that's a great help. Full HD it is then :)

I think the simplest most basic explination is...

imagine a piece of paper, with dots all over it, the 720p or 1080p is the size of the piece of paper, and the more dots there are, the more detail there is/can be

-- saves explaining screen sizes and resolutions to people explaining it that way :)

Not sure about the bit from Ghozer, where he says:

"'HD Ready' means that the TV will accept a standard Digital HD signal from FreeView,..."

I thought the "Freeview HD" logo was required for this to be true. I've been looking for a new TV and thought if it didn't say "Freeview HD" then it may well be a HD TV, but not able to process the new HD content?

From this page:

http://www.freeview.co.uk/freeview/Services/Freeview-HD2

It says:

"The first Freeview HD boxes will be available in February 2010. Freeview HD TVs will be available from March and Freeview+ HD recorders will be available later in Spring 2010. You can choose from a range of manufacturers, prices and product features. But they all come with 'just-like-real-life' picture quality and 'hear-a-pin-drop' sound from Dolby."

If you buy a full HD TV now, it'll be fully capable of handling the signal from a Freeview HD box. If the TV says Freeview HD on it then it just means you won't have to buy an external freeview HD box. Although as far as I'm aware, freeview HD is in the process of being rolled out now and isn't available everywhere at the moment, hence the reason you probably won't see that many TVs with it built in for at least a couple of months.

Dmh is correct, all that means is it has built in freeview HD, so no need for an external freeview HD box..
