How many pixels in 4k


Do you want to replace your current television set with a new one? You should consider not only the cost and screen size but also the resolution.

In TVs, the resolution is often presented in different numbers that confuse a lot of potential buyers. If you come across a 4K, it can either be 3840 x 2160 pixels or 4096 x 2160 pixels. Most digital cinemas use 4096 x 2160 pixels, while home televisions use 3840 x 2160 pixels. A 4K TV offers up to four times the number of pixels present in a standard HD TV. Paying attention to the resolution is essential when purchasing a new television. Here is more!

Introduction to resolution

The resolution is an essential part of TV hardware. It is used to show the specific number of pixels that compose the TV picture. Every television, whether an older or most recent version, has a specific resolution. The older TV models have a resolution of 720P and are composed of about a million pixels. Large TVs that have a resolution of 1080P are made up of about 2 million pixels.

Resolution is an important specification that is highlighted in different TV models on sale. When you choose a 4K TV, you should expect a high tech television that should perform well. Such a TV can deliver better performance compared to those that have lower resolutions. The resolution of a TV can help you determine the level of picture quality you should expect from a TV. Though the resolution is not the only determining factor, it can help you gauge different televisions during shopping.

Though the resolution does not change with the screen size, the number of pixels changes as the screen gets larger. As you choose a TV, you should focus on the resolution and get one that can offer excellent HDR performance and great color. Do not forget to select a TV from one of the reputable companies such as Sony, Vizio, Samsung, or Panasonic. TVs from such companies have fewer issues compared to those from less known brands.

What is the 4K resolution?

Most of the current TVs that are available in the market today deliver 4K resolution. Large screen televisions that use the 4K resolution offer better-detailed pictures than those with lower resolutions. Commercial digital cinemas that use 4K resolution choose the 4096 x 2160 pixels option. Most large TV screens, on the other hand, use the 3840 x 2160 pixels option.

Choosing such a TV can help you enjoy better detail than getting a TV that delivers a resolution of 1080p. Though 1080p resolution looks great on some TVs, choosing a 4K TV is advisable since it has better-looking images.

When you choose a 4K TV, you should not see the pixel structure even when you are close to the screen. Such a TV should offer smooth edges. This is a clear resolution that captures more texture and detail. The only resolution that does better than 4K is 8K. Choosing a 4K resolution enables you to enjoy a more immersive streaming experience.

Most 4K TVs are big size electronic devices that are at least 50 inches. 4K and UltraHD are not different since they refer to the same type of resolution. Thanks to advanced technology, you can easily find a lot of 4K content in different places. Different streaming services, such as Vudu, Amazon, Netflix, and iTunes, have 4K available. You can also find 4K content through the Blu-ray disc format. Though most Blu-ray disc players use the 1080p resolution, choosing one that contains 4K resolution can give you a better experience. If you are a gaming enthusiast, you can also find 4K content in gaming consoles such as Xbox One and PS4 Pro. Video cards in a PC also offer games at 4K resolution.

Satellite and cable, however, do not provide 4k content. This means that you may not get primetime shows such as CBS, Fox, NBC, or ABC in 4K. If you like accessing different types of content through cable, your choices will be a bit limited. Comcast is among the few cable providers that seem to offer 4K on-demand and live programming. If you already own a 4K television set and use cable, you should contact your cable provider to find if it provides compatible 4K services.

Though you can get a good experience from viewing 4K shows on a corresponding screen, you can also choose to view 4K content on a projector or 1080 set. In this case, the 4K resolution is downconverted to fit the 720P or 1080 P resolution. You may realize a difference when it comes to the picture clarity and color when using the set.


Choosing a 4K screen can help you enjoy life-like images and great visual depth. This is one of the highest resolutions that most modern TVs use. 4K can either have 3840 x 2160 pixels or 4096 x 2160 pixels. Digital cinemas use 4096 x 2160 pixels while home televisions use 3840 x 2160 pixels. You may also hear some people referring to 4K as Ultra High Definition (UHD).

Choosing a TV that offers 4K resolution can help you enjoy an excellent viewing experience since it has among the highest display densities. Apart from resolution, you should also look at other factors during purchase, such as color consistency and design.


Why should I consider buying a 4K TV?

Such a TV can help you enjoy a better viewing experience since it offers more depth and enhanced video display images.

Should I choose a 4K or 8K resolution TV?

This depends on your preference. Though an 8K screen has better resolution than a 4K screen, few 8K TVs are available. 4K TVs are not only readily available but also cheaper.
