I am considering purchasing a widescreen HDTV compatible (Toshiba 57HX83)TV . I do not intend to purchase a STB from my satellite provider. My reason in purchasing widescreen is to avoid getting the black bars that I now get on some programs example ER and others on my older TV set.
What will happen on my new widescreen TV set to programs that are not broadcast in widescreen/HDTV, but in the SD broadcast?? Wil I get black bars on the sides vs. the top and bottom??

absolutely you will. unless you stretch the picture with your tv settings or in some cases, the hd recievers settings.
myself, i can stretch the picture with both or choose gray bars or black bars. i dont stretch the picture though. you lose clarity and it dosent look "real" if you know what i mean.

I have recently purchased a 32 inch Sony TV (a conventional tube TV) that is HDTV ready but has the conventional 4:3 screen ratio. If I get an HDTV receiver from Bell Expressvu, which is my satellite service provider, can I get it in a $:3 ratio or does it have to be in 16:9. I'd like to have the choice.
Comment from Admin:
The Bell ExpressVu 6000 STB for HDTV can be programmed in the HDTV Set Up menu allows the selection of 4:3 or 16:9 aspect ratio, Y, Pr, Pb or RGB video format and 1080i 0r 720p scanning format. In the 4:3 mode, 16:9 HDTV programs may not fill the whole screen.

I have been reading this forum for a while now and have got a lot of useful info. I recently purchased a LG DU34FZ20 HDTV widescreen (with built in ATSC tuner) and I am very impressed with the reception. I live in King City, On. and from my 25 year old antenna that does not turn anymore I am receiving some excellent HDTV (it does have a Radio shack amp). City Hd, Toronto 1 HD, CBS HD, ABC HD, NBC HD, PBS HD and several others. The picture quality is amazing!.
On a side note I am confused about the aspect ratio. When the show is in HD it is quite obvious however when I watch a DVD that says it is in wide screen the picture does not always fill the screen. Why is this?.
Over all this TV was worth the money. I have only had it for a few days and am still learning the functions.

Glad to hear that you are getting good reception and enjoying all the benefits of HDTV. It is really spectacular sound and pictures. With regard to the DVD question, wide-screen may not always be 16:9 aspect ratio and on some the picture may be encoded in the wider aspect ratio of the original movie screen for full theatrical effect. When viewed on the HD television at 16:9 small black bars at top and bottom may result. Other DVD’s may be encoded at 16:9 and thus fill the screen completely.

Apect Ratios
I just bought a Sharp AQUOS 32" Widescreen HD-Ready Flat-Panel LCD and a Yamaha CinemaStation DVX-S150 home-theatre-in-a-box.
My problem is with viewing aspect ratios.
The widescreen has a 16:9 widescreen aspect ratio and 6 selectable view modes: Sidebar, Smart Stretch, Stretch, Zoom, Dot by Dot (for PC), Normal (for PC).
The thing I don’t understand is that none of these view modes allow me to view widescreen movies without actually stretching the picture to ill the screen. I want the see the movies in the same aspect ratio as is on the DVD.
The Yamaha CinemaStation DVX-S150 has two settings in the picture output: Letterbox and Widescreen. I have it set at Widescreen.
The only view modes that I have when viewing DVDs is Sidebar, Smart Stretch, Stretch and Zoom.
How can I see the film in the same aspect ration as is on the DVD, without the sidebars but without actually stretching the picture ?

Black Bars
Hello I have a widescreen 57 inch Sony rear projection television and there are always black bars when I want to watch HDTV so how can I solve this problem??
Comment from Admin.
It is hard to be definite in the absence of specific information, but be aware that much of the material shown on HDTV channels is converted from SD 4:3 aspect ratio material, leaving bars (black or otherwise) on each side. Real HD material is created in the widescreen 16:9 format and thus fills the screen. Make sure that the material you are watching is really HDTV wide screen. Do the bars go away then? Incidentally there is a good discussion of all this in the HD Televisions section in the Aspect Ratio thread.

Letterboxed TV programs on widescreens
I have recently got a widescreen TV. I had thought that the shows that re shown in widescreen would now show across the screen without the black bars on the top and bottom (like some DVDs now do). But, the TV shows still appear "letterboxed" even though the screen is widescreen. Am I missing something?
Comment from Admin.
This question has several threads running through it and the key ones are:
1. Programs originated in HDTV are in widescreen 16:9 aspect ration and are transmitted that way. They will fill your screen without bars at the side or top/bottom.
2. Programs originated in SD can be originate either in widescreen, (16:9) or in legacy (4:3) format, with the latter predominant. Likely an SD or NTSC transmission will send them in 4:3 so bars will appear at the sides of the widescreen display or the top/bottom of the picture may be cropped, dependent on display settings. The 16:9 SD would be transmitted in this case with bars at the top/bottom for 4:3 viewers, so on the widescreen display it would have bars all around, a so-called postage stamp mode.
3. Much of the material sent as HDTV is actually up-converted 4:3 NTSC or SDTV. Much of this is simply sent in the 16:9 aspect ratio window of HDTV with bars at the sides. The picture quality may also be below HDTV standards, when viewed on the HD display. This is not a good arrangement if the display uses CRT or plasma technology, as it is possible to inflict some permanent burn-in damage to the screen, making full-screen operation preferred.
4. From time-to-time one sees material that has been originated at 16:9 HDTV, then down-converted to 4:3 for SDTV ((bars at top and bottom) and then up converted to HDTV again (bars at the side) resulting in “postage stamp” viewing. Broadcasters try to avoid this as much as possible.
Your display includes a format converter and you can usually set this up to your tastes. I hope the above will give you some guidance in this thorny problem. Real HDTV should fill the screen, for up-converted SD to HDTV you may have little choice and for SD/NTSC there are a number of options to select.

16:9 vs. 4:3 converter
Have a new Digital TV and found out that it is only in the format 16:9 and has no converter integrated to switch to the format 4:3. It is quite annoying when you see all regular TV programs with a stretched image. Is there somewhere a converter that could be add to the TV? Is there any help coming from cable providers for that purpose, I must not be the only one with that situation! Thanks
Comment from Admin:
Hard to believe that a manufacturer would produce such a set, as NTSC (4:3) will be here in Canada for some time to come and in the USA continues until early 2009. The simplest solution is to get an ATSC STB (LGE, Samsung and others make good ones) and use your TV set just as a 16:9 monitor. The STB’s include the necessary format convertion.

4:3 HD
On Rogers Cable, HD programming automatically goes from 16:9 (most prime time shows) to pillarbox to matchbox. Some of the pillarbox 4:3 looks really clear (mostly commercials) - Is that HD in 4:3?
Comment from Admin.
This problem comes about when a widescreen (16:9) program is converted to SD (4:3) and then subsequently up converted back to widescreen HDTV for delivery to the HD television. The broadcasters try to avoid this, but they may not control the original source and hence have to live with it.
For a fine tutorial on this and other aspect ratio considerations go to http://www.cdtv.ca/en/whatsnew/aspect-ratio.htm
And follow the instructions.
