HDTV Reviews: Unbiased Buying Guide for EveryoneTerms Used in HDTV Reviews To maximize the benefits of an HDTV review and arrive at an informed decision in buying your own high-definition television, you need to understand the terms that describe HDTV sets. HDTV, as you may know by now, stands for "high definition television". This technology allows consumers to play games and watch movies or television shows with a wider and clearer image and sound. As you may hear from computer, camera or television specifications, pixels are the smallest elements of a monitor display or television picture. These pixels are comprised of blue, green and red elements. When reading an HDTV review, pixels usually come with small, square and closely placed together, compared to a regular or analog TV. Because of this, an HDTV yields five times better visual than other television formats. When you see a "line", this means a row of pixels. The standard analog television displays 480 lines with 720 pixels on each line (with 345,600 pixels used). An HDTV can display up to 1024 lines with 1920 pixels used on each line, with 2,073,600 pixels used. Another factor being rated with HDTV reviews is the aspect ratio. This ratio is about the screen width versus the screen height. Just like theater displays, an HDTV's aspect ratio is set at 16:9, compared to analog televisions with a ratio of 4:3. HDTV reviews can have a beneficial meaning to your window-shopping when you understand each specification and terms written. Knowing how the HDTV works with other customers can give you an idea of the outcome you will have once you install your high-definition television with your entertainment system. |
