CRT 16:9 Monitors
CRT, which stands for cathode ray tube, is a type of technology that has been used in televisions and monitors since they were first invented. They continued to be the dominant television technology until the late 1990s and early 2000s. Although now largely considered a legacy product, CRTs with a 16:9 aspect ratio are still compatible with many computers, as long as you have the right interface or converter.What is a cathode ray tube?
A cathode ray tube displays images by emitting a stream of electrons from inside of a vacuum tube located at the back of the television or monitor. In most color sets, the screen itself is coated with phosphor, which displays colors based on the intensity of the electron beams emanating from the vacuum tube. The cathode ray gives the set its large, bulky appearance. However, ultra-slim cathode ray sets have been produced for the consumer market since the early 2000s. These slim CRTs have a thinner footprint than the bulkier alternative. Sometimes the CRT displays are as much as 40% smaller. Modern cathode ray sets incorporate more advanced technologies to produce a clearer, cleaner image for viewing videos or playing games. Most older CRTs are only capable of displaying a standard definition image, but modern versions are capable of a high definition image as well.What is an aspect ratio?
The aspect ratio refers to the proportion between the height and width of the image. There are generally two types of ratios which have become the industry standard for screen sizes over its history. A 4:3 ratio, also known a full-screen ratio, features four horizontal pixels for every three vertical ones (pixels are the small dots that form the image on the set). A 16:9 ratio, also known as a widescreen ratio, contains 16 horizontal dots for every nine vertical ones, although a 16:10 ratio is also sometimes used instead. Older cathode ray sets produced before the 2000s typically had a ratio of 4:3. Until the adoption of flat-screen sets, the 16:9 ratio was mostly restricted to film theaters and a few novelty television sets. But since the early 2000s a 16:9 or 16:10 ratio has become the standard with almost all displays. The 16:9 ratio gives a wider view of the image, whereas 4:3 tends to cut off part of the image at the edges. A 4:3 screen can only display a 16:9 image by zooming in or cropping it to fit the set.How does the ratio affect the resolution of the image?
The aspect ratio measures the proportion of the TV screen or computer monitor screen. The resolution measures the actual number of dots present, usually given as the width by height. Changing the ratio will change the resolution of the image. For example, a typical 4:3 standard definition monitor would have a resolution of 640 by 480 phosphor dots, but a similar 16:9 set would have approximately 853 by 480 dots instead. The latter screen would, therefore, have a larger number of total dots giving a better picture quality. There are also ultrawide monitors available which are available as full HD monitors and LCD monitors. Some brands that provide CRT 16:9 monitors are Dell, Sony, Nvidia, and Trinitron.
