We already have a 1080p TV in our living room. The new TV will be for
the bedroom and will have a 32" screen. We have two Sky HD+ boxes.

When we bought our 1080p TV we were told that Sky was broadcasting HD
only in 720p, not 1080p, and that the 1080p picture was derived from
that 720p signal by the TV. What I need to know is will there be any
loss in picture quality from choosing a 720P TV?

To digress slightly, I have a CRT television in my kitchen. We are
having our switchover (stage 1) next week. One option is to buy a
decoder box. If I buy an HD decoder will it output HD on a scart or
only via HDMU and would it in theory provide a better picture.

I say 'in theory' as it is a 14 inch television so I don't imagine I
will go down this route.

No, you'll only get an SD downconvert via the scart, however that would still
look a lot better than viewing the equivalent SD version of that HD channel,

The HD channels have far fewer artefacts than the SD ones, so you will benefit
from that viewing on an SD only TV.

Well, probably that size screen is not worth the effort/expense.

Usually only HDMI, other connections are possible but rare.

Not worthwhile on such a small screen, in any case virtually certain to
be impossible on your existing CRT TV.

Probably right but it was suggested in another thread that Tesco were
knocking them out for £30 so the extra expense might be fairly
minimal. Not sure what effort is involved though.

Oh, only the effort of spending money :-)

Though have a good read of this before you do buy:-

a non 1080p TV (and do these

My Samsung "HD Ready" LE26A456 has a resolution of 1366 x 768.

It upscales a 720 input and downscales a 1080.


AFAIK this applies to all the not-full-HD TVs - the 768 line resolution
isn't used by any video, so everything you see will be scaled.

ISTR we discussed this before. It may not be a coincidence that 768 is
the vertical resolution of the computer display standards XGA and WXGA.


I think it is a coincidence. There's never been much market for 768
line computer displays much over 14 inches. I have no idea what the
reason is though!

Almost certainly the dot pitch will mean that the resolution in the set is
limited to current 576 4:3 broadcasts. You can either replace it, get an SD
freeview box (cheap) or pipe UHF from a digital receiver with a modulator in
another room.

Um, no.

Only via HDMI.

You would rather be wasting your time! ;-)

All HD broadcasts in the UK, whether on satellite or terrestrial are
1080i. (The BBC HD channel on DTT is currently experimenting with
transmitting some content at 1080-25p).

Have you got a primary, verifiable source for that info?
