hd or hd ready

Basically what's the difference between the two as there seems a big price difference. Thanks Ben

720p vs. 1080p

Although as far as I understand it, full HD (1080p) can't actually be broadcast. So the only difference you'll notice is when watching a full HD BluRay.

This could be complete poppycock, but I have heard it mentioned.

Grand, thanks

You probably want a 4K if you want a future proof TV you'll be happy with.

As you say, future proof.

Almost everything broadcast is in 720p as above, but Blu Ray is 1080p and the next gen of consoles will be putting out 1080p as well (hopefully).

This isn't correct: Sky Broadcasts and Freeview HD are broadcast in 1080/50i. There may be content that is captured in 720p but even then it will be scaled to 1080(i) before broadcast.

Therefore for 'film' content on a HD channel with decent bit rates (if you can find one thesedays ) then you will fully benefit from the 1080p display. This is because 24 frame/second film is sped up by 6% to 25 frame/second then interlaced to 50Hz. The TV can then perfectly recombine the two interlaced 'frames' back to 25p. No loss of resolution, just that in the UK PAL 'films' are effectively sped up by the 6% figure above. The same process applies for (PAL)DVDs, though USA (NTSC) DVDs run at 60Hz so they have a different process and they play at the correct speed (but with judder unless reverse-telecined back to 24p which many players can do).

It's different for 'video' sourced content (which is most everything else other than films), so depending on the deinterlacing method used you might end up with effectively 540p resolution (the process is effectively inteligent 'guesswork' by the TV's video processor.

Having said that, many people don't sit close enough to get the full benefit of 1080p anyway,, let alone when 4K comes out (which IMHO is a waste of time for most viewers and arguably only any use for projectors).

All very Interesting but I think the OP would be more interested in knowing that a Full HD set will have the DVBT2 tuner fitted that will be able to receive the HD channels where as a HD Ready tv will only have a tuner capable to receive the standard def channels but has the HDMI inputs and screen capable of replaying HD pictures from a HD source I.e Sky box, BluRay, games consoles etc et

??? Plenty of (if not all current) HD Ready TV's have a Freeview HD tuner!

If that were true then my 1080p 'Full HD' TV I bought 6 years ago would have a HD Freeviewtuner...it doesn't. Likewise there are 720p 'HD Ready' TVs that can receive the HD channels using their own tuner.

HD ready/Full HD refers to the screen resolution, not the tuner capabilities.

In the case of todays sets Full HD will mean it'll receive HD channels which is more benifit to the OP I think. Just an observation

I doubt if any TV company captures in 720p. Old equipment will be 576p (SD) and new stuff 1080p (HD). A lot of professional level DSLRs capture broadcast quality 1080p video now.

I was thinking more in terms of US content as they do have some content that is broadcast in 720p so I presume that it is captured this way too. However, I'm not sure whether this applies these days.

HD ready means the panel has 1280x720 pixel resolution - 720p
Full HD means 1920x1080 - which is "actual" High Definition - 1080p

Edited by WeirdNeville on Saturday 14th September 14:24

Nope...

HD Ready TV means it can display HD from an external source
HD TV means it has an internal HD tuner.
Full HD has no official meaning

if its over 720p (so 1080, 4k etc, then it will be marked). 720 isn't marked, ie;

"HD Ready" = 720p screen without HD tuner
"HD Ready 1080p" = 1080p screen without tuner
"HD TV" = 720p sceen with tuner
etc.

It doesn't, see my other post. Your TV was not property marked/advertised.
