If you’re shopping for a new TV, you’ll quickly encounter a bewildering maze of information. For someone who doesn’t spend all their time reading the latest news from the world of televisions, it can get confusing.
One of the most important things to consider is your new TV’s resolution. Should you buy 4K or one of the many alternatives? In this article, we explain how 4K resolution compares to 2K resolution, 8K resolution, and more.
What Is 8K Resolution?

4K refers to any screen resolution with roughly 4,000 horizontal pixels; thus several iterations of 4K resolution exist. They are not all the same.
For example, 4K resolution in the world of cinema uses 4096×2160 pixels (8,847,360 total) with an aspect ratio of 256:135. It is called DCI 4K.
In TV sets, the most common 4K resolution is 3840×2160. It uses 8,294,400 pixels in total and has a 16:9 aspect ratio.
Officially, 4K resolution is called UHDTV1 or 4K UHDTV. As you may know, UHD resolution stands for Ultra-High Definition resolution. Ultra-High Definition and 4K resolution are interchangeable terms. You may also see 4K referred to as 2160p.
More services and devices are starting to offer 4K. They include Netflix, Xbox One (S and X), PlayStation 4 Pro, and Prime Video. All matches at the 2018 FIFA World Cup were broadcast in 4K.

The “p” in 1080p stands for progressive scan. In simple terms, it means frames are drawn in sequence on the screen. The opposite is interlaced video in which odd and even lines are drawn alternately. It was common in analog TVs.
1080p resolution is half of 4K resolution. It has four times fewer pixels. The resolution is 33.3 percent higher than 720p displays.
Today, it’s tough to find a modern TV that doesn’t support 1080p input via HDMI cable. Most computer screens can also support the resolution. It has been available on Netflix since 2013.
