    Should you have your Sky digibox set as outputting 16:9 or 4:3. Will the screen (LG17) switch/adjust to what its receiving ?

    The reason I ask is that I currently have mine on 16:9 and I have noticed that when certain pieces of film are shown, e.g News clips during the news broadcast there is a black banner down he right hand side of the screen about 3 inches wide. When back to the 'studio' for the news it fills the screen ok.

    Sky box is going via a JS RGB to Component converter.

    I have the lg14 , my sky is set to 16.9 and havent yet seen the black bars you mention.

    I am connected with a scart to the tuner box though, so maybe its something to do with the js box.

    quite a bit of broadcast is actually 14:9, and they send the bar to fill the gap when the rest of the program is 16:9 like news 24. The LG tuner must be stretching the 14:9 picture, which the js box doesn't do. I see this quite a bit, use JS converters various.

    The 14:9 broadcasts on the BBC should display with two equal black bars on the left and right. If you are seeing only one on the right your picture is not centralised, does your screen allow you to alter picture position?

    I am not aware of how to 'centralise' the picture position.
    Can anyone help ?

    Just took this picture from today's news. As you can see just a black band on right hand side - and only during 'news clips'

    [​IMG]

    Do others with the LG (or any make) using a sky digibox see this centralised ?

    Anyone know how to sort it or is it a call to the engineers ?

    Thanks.

    As I said before I never get the problem, but I would think the screen has either been setup wrong at manufacture or its a problem with the js box.

    Try connecting via composite straight to the screen and see if it still happens.

    By the way, where did you get your wall bracket from, I need to buy one very soon.

    Widescreen TV causes many problems one being what picture you actually see. Traditionally TVs only show part of any picture with an area called overscan being transmitted but not used for content. So if your TV was a little out on settings you still saw a full picture here you are supposed to see the limits so it is annoying.

    House what picture do you get if you connect a DVD player running the THX optimiser screens down the same connection? I suspect all your widescreen pictures maybe slightly offset to the left which is easy to check on a test card.

    There are no adjustments on a SKY box, some TVs can be adjusted via service menus but I have no experience on adjusting plasmas. My new Hitachi is marginally out so that the left band is about 0.2cm narrower than the right - noticeable but not a serious problem.

    mre15 I think you are not viewing a true 16:9 image but a zoomed version as it is an obvious on all BBC News 24 transmissions on Satelite or via freeview where most foreign reports are in 14:9 ratio with small black side bands.

    It is on many big block busters like Star Wars look for the THX logo on the box, if you go to the audio or setup menu click on the THX logo and follow the instructions for Video Tests, it checks many things including screen geometry and position - very useful.

    There should be a matching black banner on the left.

    Most BBC broadcasts are 16:9 ratio, but many "live" feeds use 4:3 cameras that are scalled to 14:9. On 16:9 display this shows two black borders down the left and right of the 14:9 image.

    As well as centreing I think your picture width needs reducing too. If you measure your glass width and divide that measurement by 16, that will tell you how wide the black bar should be on each side.

    I have the THX setup on T2, I'll have a play later.

    I assume this is an engineer thing ?

    Don't believe the fault is at your end m8. Happens all the time when the BEEB news goes to regional in the evenings. This on a freeview set into a CRT TV set to 16:9.
    A black band down the right hand side.
    It comes and goes tho. depending on the type of feed , I guess.
    Don't worry about it....

    No, just changing some picture settings on your screen. Similar to contrast and brightness, but X-Y position r picture height/width.

    Even the very oldest CRT have picture positioning and sizing controls, I remember when I was a kid these were on analogue potentiometers; these days they are a digital setting.

    Usually well covered in plasma manual.

    Agree with chrise and stoomonster.

    You should be seeing 2 black bars, one on the left and one on the right.

    There should be something on your remote/menus to change the horizontal/vertical positions.

    Other than that there is nothing wrong with your setup, it is perfectly normal to see these black bars on the configuration you have (I have the same).

    Sometimes there are two bars and sometimes there is one bar on the RHS. Do you never see a bar on the LHS?

    I don't know why BBC and Sky can't get this symptom of "blowing up" 4:3 images to fit into a 16:9 screen in proportion. It's so off-putting....

    its not your tv as thats just what it looked like on my 28 inch crt on bbc news today. all so if you look at the red logo its in the right place for the picture (ie the red logo does not move when the pictuer goes back to the bbc news room.) it all so happens when bbc show childrens programs like the Rugrats, the bbc seem to show non 16:9 pictures with a black bar down the right hand side.

    hope that helps

    Got 4 plasmas at work, they are all like it too. Just never paid it any attention before! When they are in your face you just get used to it. It's definitely the broadcasters, do not adjust your set!!!
