How is horizontal resolution related to vertical resolution in a TV system?

In a TV system, horizontal resolution and vertical resolution are typically matched, meaning they are closely related and often designed to complement each other. Both resolutions refer to the number of pixels that can be displayed in horizontal (width) and vertical (height) directions, respectively. When the horizontal resolution increases, it generally requires a proportionate increase in vertical resolution to maintain a high-quality image without distortion or loss of detail. This matching ensures that the image is clear and sharp, providing a comprehensive viewing experience.

For example, if a television set has a horizontal resolution of 1920 pixels, a corresponding vertical resolution of 1080 pixels (commonly referred to as 1080p) is necessary for optimal performance. If the resolutions were not matched, the overall image quality might suffer, leading to issues like pixelation or blurriness in one direction. Therefore, the correct relationship between horizontal and vertical resolutions in a TV system is that they are matched.
