What is 4K TV? Will you buy a 4K TV when the UHD video is coming?
What is 4K resolution? Why is it important when you are looking for a new TV? In this explanation, I will explain what 4K is and explore the main differences between 4K, 8K and HD displays.
4K is a screen resolution. Ultra HD screen resolution, also known as UHD, 4K or 4K UHD. It has become the default screen resolution for all TVs and many PC monitors you see.
Because it has become the default setting, 4K has surpassed HD and full HD and become the most popular resolution for those who want clear and exquisite TV pictures.
However, although 4K is very common now, it is not the only TV technology resolution you can find when looking for a new TV. Especially if you are willing to spend more money. For example, 4K technology now faces competition from 8K resolution TV.
As you might expect, 8K has a clearer resolution than 4K, so it has begun to attract attention in the TV market. However, at present, 4K TV still dominates. Let me know more about what they are and how they work.
The good news about 4K TV is that you don't have to watch only 4K content. The best 4K TV can display movies and TV programs with lower resolution. However, you can then enlarge this content to ensure that it looks normal on the 4K screen.
However, the original resolution of 4K may not be the ultimate inducement to buy your next TV. On the contrary, other cool technologies built into many 4K TVs, including quantum dots, OLED panels and high dynamic range (HDR), may ultimately affect your purchase decision. After all, today's best TV is 4K or 8K TV.
What is 4K resolution?
4K resolution, at least the way most TV companies define it, is 3840 x 2160 pixels or 2160p. From this perspective, the full HD 1080p is only 1920 x 1080. The 4K screen has about 8 million pixels, which is about four times as large as your current 1080p setting.
Think of your TV as a grid with rows and columns. Full HD 1080p image is 1080 rows high and 1920 columns wide. The number of 4K images in two directions is about doubled, and the total number of pixels generated is about four times. In other words, you can put each pixel in the 1080p setting into a quarter of the 4K screen.
