Where can you buy a High Definition television with an aspect ratio of 16 to 12?

HD television formats always use an aspect ratio of 16 : 9. For that reason, all HD televisions have that aspect ratio.
A 12 : 9 (or 4 : 3) aspect ratio is only used with standard definition video signals so any 4 : 3 television will be a standard definition model only.

What improvements to broadcast television and videotapes does high-definition and digital television broadcasting bring?
pictures will have better quality because of an increase in the number of pixels and a change in the aspect ratio of the picture.
What is HDTV?
HDTV stands for High Definition Television. HDTV is a digital television broadcasting standard. Since it is digital, the signals are composed of ones and zeroes -- the language of computers -- instead of waves. HDTV digital signals can contain more information that the old systems. The data can be compressed to allow up to six times more information in the same range of radio waves. Therefore, a broadcaster can send multiple data streams through the limited airwaves they are allowed to use. This is known as multicasting. The old TV standard was for 625 lines (not 525 lines across), with the television screen having a 4:3 "aspect ratio" (that is, the dimensions of the TV screen would be IN A RATIO of 4 to 3). Aspect ratio has very little to do with the broadcast standard - widescreen TV's are not necessarily HDTV (Mine's standard 625 PAL). HDTV can give display of 720 or 1080 lines, and the aspect ratio is 16:9. You can access HDTV with a digital converter on an old television. But this will not give you its full benefits. Newer models of TVs are being built with integrated receivers for HDTV.
What is the difference between taper ratio and aspect ratio?
(For televisions) Aspect ratio is the ratio of the width of the television screen to the height. TVs do not have taper ratios. (For airplanes) Aspect ratio is a ratio of the wing span squared to the wing's reference area. This gives you a sense of how thin/slender a wing will appear from the top view of the aircraft. High aspect ratio means a long/extended wing. b² / S ("b" is wing span, "S" is wing area) Taper ratio is the ratio of the wingtip's length to the wing root's length. This gives you a sense of the angle the shape of the wing. High taper ratio means a triangular shaped wing. t/r ("t" is length of the wingtip, "r" is length of wing's root)
What is the difference between HDTV and digital television?
High Definition (HD) is a form of digital television. High Definition is the highest quality of digital television available with the highest resolution, which results in superior picture quality. Listed below are some commonly found digital television resolutions. High Definition is also broadcast in widescreen format, otherwise known as 16:9 aspect ratio. Standard definition is broadcast in 4:3, which is a similar format to analog. Here are some commonly found digital resolutions: • 640x480 pixels (Standard Definition) • 1280x720 pixels (High Definition) • 1920x1080 pixels (High Definition - Often referred to as Full HD or True HD because this is the highest resolution available.)
How do you change the aspect ratio on a tv?
This a way to describe the width compared to the height of the picture. Standard TV is 4 by 3 and HDTV is 16 by 9, meaning the picture is wider than it is high. Movies are made in many different aspects but always wider than it is high.
Is a LCD TV a high definition TV?
It depends on the LCD you get. LCD, Plasma, and Rear Projection TVs all come in various models with different capabilities. If you're looking for the highest HD picture capability you can get then look for a TV that can handle a 1080p signal. 1080i and 720p are also considered high def, but 1080p is what you're looking for if you're going for Blue Ray, XBox, upscaled DVDs, etc. There's really no reason to not get 1080p unless you're really strapped for cash. One thing to think about with LCD is breakability. Yes, they have great pictures, but the monitors are actually pretty easy to break if you accidently drop or run into them with something.
What are some of the differences between a computer monitor and an LCD TV monitor?
The main difference between a computer monitor and an LCD TV monitor is the pixel density, which is nearly twice as high on a computer monitor. This is the main reason that a computer monitor is more expensive. In addition, most computer monitors have a 16:10 aspect ratio, while TV monitors have a 16:9 aspect ratio.
What is wide screen presentation enhanced for 169 TV?
It's all to do with aspect ratios. An aspect ratio is the shape of an image, so a film format that is twice as wide as it is high will have an aspect ratio of 2 : 1. Traditional television has an aspect ratio of 4 : 3, so it is 4 wide and three high. Widescreen television is 16 : 9 so it looks wider than 4 : 3. and that is where the problems lie - film is normally a different aspect ratio than television so when a film is converted to DVD, the shape has to change. When it is being mastered, there is now a choice of 4 : 3 or 16 : 9 aspect ratios. The choice in this case is to format the film to 16 : 9 hence the claim "enhanced for 16 : 9" in fact, it is rarely enhanced because every shot will have part of the image cropped from the sides (or the top and bottom in some cases). There are some clever gadgets called ARCs that do the job (Aspect Ratio Converters). Not only do they re-size and re-shape the image, they can also control the area of the original image that is captured. Most films are converted dynamically, meanign that the area converted will move from one shot to the next.
What is the difference between high definition and plasma television?
High definition refers to the quality of the picture, and plasma refers to the type of screen. All plasmas will be high definition, but not all high definition TVs will be plasma.
What does the OLED screen do?
An OLED screen is typically used in televisions that use a high definition display. The OLED light is what gives the high definition televisions a clear high definition picture.
What does HDTV stands for?
HDTV Stands for High Definition Television
How do you tell if a DVD is wide screen or full screen?
Widescreen DVD's are designed for modern TV's with an aspect ration of 16:9 (almost twice as wide as tall). Most movies made in the past 50 years will fit better on these screens, although most will show a small band of black at the top and bottom of the screen. Full Screen DVD's have the movie edited to fit on an older TV with a 4:3 aspect ratio (almost square). These movies will play on a widescreen TV, but large black bars on the sides (pillarboxes) will be present and some of the movie's original screen space is lost in the edit. Most TV shows created in the past 5 years are formatted for Widescreen viewing, which is also the aspect ratio of High Definition television.
