I've just been setting up an HD-ready TV for my Mum. In the
past she's noticed that friends' HD-ready TVs have "distorted"
pictures. The one we selected in the shop (to check it wasn't
too dire) showed a normal picture.
However, while I was setting it up, I noticed that the analog
channels showed peoples' faces as being fatter - literally, they
looked like they'd put on a couple of stone. Mum reckoned this
was the same as on her friends' sets.

Comparing the TV, on an analog channel, with my properly set-
up digital TV, showed that indeed the picture had both sides
clipped, while still keeping the 16:9 aspect ratio. The result
is that circles are flatter and wider than they should be, and
the edges have been lost.
Using the built-in DVB, the channels display correctly.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^
- LOOK HERE! -


There are no controls for fine-tuning the horizontal size of
the picture.

Have other people noticed this? I'm surprised that the effect
seems to be common (well, among her friends, anyway) and that
the owners are either unaware or dont care about the poor setup.



For ****s Sake! There are causes and solutions to this issue with
the mysterious HD-ready TFT that you're reluctant to mention the
name of. This is just one example of how to find support, FAQ, and
solutions to any problem with your mysterious flatscreen.

Read the post. I never said I was having a problem - or needed support.
The highlighted line shows that I *did* get the set configured
correctly.
When you read the thread, you will see that apart from the anecdote, I
was reflecting on the number of other poorly configured sets that
people seem willing (or happy) to watch.

Ignore him, Peter. He's a ****.

The screen is 16:9.

The only source of 16:9 broadcasts is from DVB.

Analogue sourced pictures will be 4:3, either full screen, or (in
most cases) 14:9 letter box within a 4:3 raster.

You will not be able to fill your 16:9 screen with an analogue
sourced picture and not have black bands and/or cropped sides
and/or geometric distortion.

The only correct way to view analogue broadcasts is with black side
bars, and also narrow bands top and bottom (in the case of 14:9
letterbox as broadcast)

Yes, it's just a shame that the "auto" mode doesn't have the smarts
to realise this - and mangles what could be a perfectly normal
picture.

There is no consistency with "auto" mode across different
manufacturers. For example my new Panasonic LCD requires the zoom to
be set to 4:3 and it will then display correctly, using the wide
signal either input from scart (DTT box set to TV = 16:9), or via its
internal DTT tuner, to display 4:3, 16:9 (and some 14:9 with thin
black bands at the left and right of the screen, other times
letterboxed in 4:3) correctly. My old JVC required the zoom to be
set to "auto" and then would always display the correct aspect from
the internal analog tuner or the DTT box connected by scart.
(Including 14:9 as described above).

The two sets are consistent in that they display identically with the
zoom / aspect settings set differently.

Reading the TV manual does not always help. The Panasonic manual tells
me all about the black magic that "auto" does to screw up the
picture so it fits the full screen, but nothing about how to display
the correct aspects unmangled. Experiment revealed the 4:3 mode
produced the desired result.

I thought your new Panasonic was plasma not LCD?

Just imagine you are watching Vanessa Feltz and Chris Moyles rather
than Posh and Becks.

Something isn't set up properly (sometimes deliberately due to ignorance).

Is the TV using an internal tuner, or being fed from an STB of some
sort? If it's from an STB, the STB needs to be informed via its menus
that the TV it's feeding is 16:9 rather than 4:3

Otherwise there will be an aspect ratio button somewhere on the remote
(often they look like a rectangle with a cross through it, or nested
rectangles) or within the settings menu an option for "auto aspect
ratio" or similar.

The one thing to bear in mind is that it is normal to have black bars
left&right when watching a 4:3 program on a 16:9 TV, some people feel
they have to adjust the aspect ratio to fill the whole screen (as
they've paid for it) this *will* result in either stretched fat people,
or people with the tops of their heads cut off - try to explain why they
shouldn't do that!

My new telly is annoying in that respect. It automatically stretches
4:3 images to 16:9 unless you select 4:3 from the menu. But then you
have to switch it back to 16:9 manually afterwards:-(

Marky P.

Actually, ignore what I just said. If my telly is set to 4:3 it does
switch automatically back to 16:9 and back to 4:3 again :-)

deliberately *or* due to ignorance - can't be both! ;-)

I think you are missing the point. The problem is only visible on
analogue transmissions using the built in tuner.

The one thing to bear in mind is that it is normal to have black bars
left&right when watching a 4:3 program on a 16:9 TV, some people feel

or people with the tops of their heads cut off - try to explain why they

Indeed. However it is worth remembering that most stuff broadcast in 4:3
these days is actually letterboxed 14:9, and hence will have black bars
visible on the top and bottom of a 4:3 set. Widescreen sets handle this
in different ways, but not all have a 14:9 setting, leaving the choice
of the 4:3 setting showing the correct geometry but with black bars top,
bottom, left and right, or full screen with slight horizontal stretching.

Even though I missed Peter's point on analogue v.s. digital (the clue's
in the title) and thought he hadn't found a way to get the TV to display
proper pictures, I *did* mean both - if someone is ignorant of the fact
they ought to watch 4:3 programmes *in* 4:3, then they will deliberately
stretch them to 16:9.

You have me mixed up with someone else. Probably Marky, who I note has
found that his Panny works the same as mine in 4:3 mode.

Yes, you're right, it was Marky I got you mixed up with. Sorry about that.

I think brands seem to keep the same aspect adjustments across their
range. So all Panasonics will have the same selections, as would all
Samsungs etc. Must be in the software.
