Display Resolution

When it comes to the features of HDMI cable, it is described as follows:

"

The current mainstream HDMI 1.4 theoretically supports 1080P 144hz, 2K 75hz, 3840 x 2160/30hz, 4096 x 2160/24hz.

HDMI 2.0 has a bandwidth of up to 18Gbps and supports 1080P 240hz, 2K 144hz, 4K 60hz, and 5K 30hz.

The latest HDMI 2.1 bandwidth capability increases to 48Gbps, which can support 2K 240hz, 4K 120hz, 5K 60hz, 8K 60hz.

"

The 1080P / 2K / 4k / 8K mentioned here refers to the display resolution.

What is the resolution?

Resolution is the number of pixels used to make up an image. A high resolution display allows you to view more detail in your favorite games, movies and TV shows.

While resolution is not the only channel for image quality, it is important and most people will easily notice the difference between enjoying a high-resolution TV and a low-resolution TV. The resolution of the media itself is also important. While modern upscaling technology has improved significantly, your TV will only see best when it displays content with the same resolution.

Resolution is the number of pixels on a monitor or screen. A single pixel is the smallest unit of measurement of display resolution and is a small dot on the screen that cannot usually be seen individually by the naked eye. The higher the number of pixels, the higher the clarity of the display.

You can see more detail through the content of high-resolution screens, but they only show the same information. Although high-resolution screens have become increasingly popular in recent years, it has taken a few years for content to catch up. Although Netflix's streaming media service was the first to upgrade to 4K. but in recent years, Blu-ray players and game consoles have also caught up.

Here's a sheet for display resolutions as below.

Determinants of picture clarity

We can feel whether the HD picture is detailed enough, with the resolution of the video, the size of the display, and our distance from the picture.

Display size is also a factor. 65" TVs and 32" TVs can share the same resolution, but due to their size difference, the pixels on the larger display are larger because the same image is stretched out over a larger surface. 55" TVs require a distance of 7 feet to notice individual pixels. If you sit anywhere other than 7 feet, you will not be able to tell the difference between a 4K TV and a 1080p TV. 65" TVs require a distance of 4 feet to tell the difference between an 8K and a 4K TV. This is closer than most people are comfortable sitting at.

What are pixel dots?

Pixel dots are the smallest light-emitting unit of the display screen, consisting of red, green and blue pixel units. The screen, in fact, is composed of the pixel dots enlarged as shown below, and on each small pixel dot, there are red, green and blue (RGB) three primary colors, red (R), green (G), blue (B) three color channel changes and their superposition on each other, you can get a variety of colors that humans can see. A whole screen, which is composed of a number of such pixel dots. And a screen, its ultimate role is to infinitely restore the real picture.
