The dimensions of a 55-inch TV can vary depending on the specific model and manufacturer. However, the typical dimensions for a 55-inch TV are approximately 123.2 cm (48.5 inches) in width and 69.9 cm (27.5 inches) in height. These measurements refer to the actual screen size of the TV, excluding the bezel or frame around the display.

Note that 55 inches refers to the TV's diagonal length, which comes from measuring from the upper left-hand corner of the actual TV screen to the lower right-hand corner.

You can measure the dimension of a 55-inch TV (138cm) by calculating the diagonal length, from the upper left-hand corner to the lower right-hand corner.

Resolution is a term that describes the density at which these minuscule dots, known as pixels, are arranged on the display. These individual pixels come together to form the image that is visible on the screen. As a result, a greater pixel count directly correlates with a higher resolution, yielding a clearer and more detailed picture.

55 inch TVs are offered in both 4K and 8K resolutions. The 4K version features a resolution of 3840 x 2160 pixels, providing a high level of detail and clarity in the image. The 8K version provides even greater detail and clarity, with a resolution of 7680 x 4320 pixels, which is four times the number of pixels found in a 4K TV. With this ultra-high resolution, it becomes possible to display incredibly sharp and detailed images.
