How Many Pixels In 4K Resolution? (2023)

When it comes to high definition, 4K’s exceptional clarity and stunning detail is head and shoulders above the rest. If you’ve ever wondered where that clarity comes from, or exactly how many pixels are packed into a 4K display, don't miss this article. Here, we’ll explore the secrets behind 4K and delve into the precise pixel count that fuels its visual brilliance.

What Is 4K Resolution?

4K resolution is a display or video format comprised of roughly 4,000 pixels of horizontal resolution. It is a gauge of how clearly images appear on a screen.

Because 4K resolution’s increased pixel density allows for finer details and more vibrant colors, it provides visually stunning and highly detailed content and a more immersive viewing experience. Though this is especially effective on larger screens, 4K is used in a variety of applications, including television sets, computer monitors, digital cameras, video production, streaming services, and gaming.

When Was 4K First Developed?

4K technology dates back to 1984, when the GPU ARTC HD63484 successfully created monochrome images in 4K resolution. Seventeen years after that early-stage technology, the IBM T220/T221 screen is capable of displaying 4K content was introduced.

Following this innovation, many universities researched and refined the 4K format, and in 2010 4K cameras started being produced by top media and display manufacturers. This led to the format’s wider usage and adoption, and the technology became even more popular after streaming websites like YouTube began supporting 4K resolutions.

Eventually, 4K made its way into cinemas and movie theaters, offering audiences a stunning visual experience.

How Many Pixels/Megapixels Are There In 4K Resolution?

4K resolution refers to a display or image size that contains approximately 3840 pixels horizontally and 2160 pixels vertically. Multiplying these values delivers a total of 8,294,400 pixels, which is commonly rounded up to either 8.3 million pixels or 8.3 megapixels.

4K vs 8K:

While 8K’s delivery of four times 4K’s resolution result in sharper images with more detail, 8K displays are significantly more expensive and have limited content availability.

4K vs 5K:

5K offers sharper and more detailed images due to its higher pixel density, but the difference is most noticeable on larger screens, and their displays require more powerful hardware for running applications. This advanced technology also makes them more expensive than 4K.

4K vs 1440p:

While 1440p can still be appreciated on smaller screens and has the advantage of requiring less processing power and higher refresh rates that offer smoother motion, 4K provides sharper and more detailed images. 4K’s higher pixel density also provides more accurate and vivid colors. This is most noticeable at closer viewing distances.

4K vs 1080p:

4K delivers four times the pixel count that 1080p does, and offers finer details and sharper images. While 4K displays can enhance the appearance of non-4K content, opting for a 4K display ensures compatibility with newer content and avoids the need for upgrades in the future.

4K vs 3440 x 1440:

Though 4K offers higher pixel density and greater resolution, 3440 x 1440 is an ultrawide format that is ideal for immersive gaming and multimedia experiences, and many games and media applications offer ultrawide support. Still, 4K content is widely available, where 3440 x 1440 content has more limited availability.

4K vs 5MP:

4K offers higher pixel density and sharper images than 5MP, has wider content compatibility and is suitable for video playback, gaming, and professional video editing. 5MP is most commonly used in surveillance cameras and for specific professional applications.

How Many Pixels In 4K Videos?

4K video is a video resolution that’s commonly used in display devices and for content creation. It offers a higher level of detail and clarity than lower-resolution formats. Its resolution is 3840 pixels horizontally by 2160 pixels vertically, which is frequently referred to as 2160p or UHD (Ultra High Definition). Multiplying these two numbers provides a total of 8,294,400 pixels.

To understand the impact of 4K video, imagine a grid consisting of 3840 columns and 2160 rows of tiny, individual dots. These are known as pixels, and each pixel represents a single unit of color that contributes to the overall image displayed on the screen. The more pixels there are in a given area, the sharper and more detailed the image will be.

4K Pixel Counts And How They Impact Different Devices

4K resolution affects pixel count on different devices in unique ways. Below we’ll explore popular examples across various platforms.

How many pixels in a 4K TV?

A 4K television typically has a resolution of 3840 pixels horizontally by 2160 pixels vertically, resulting in a total of approximately 8.3 million pixels. Though this resolution is consistent across different screen sizes in the 4K category, pixel density can vary depending on screen size.

A 50-inch television with 4K resolution has a higher pixel density than an 80-inch unit with the same resolution. The smaller television screen packs the same number of pixels into a smaller area, resulting in a sharper image.

How many pixels in a 4K security camera?

4K cameras capture images and videos at a resolution of 3840 x 2160 pixels. This is the same resolution as that provided by 4K televisions and monitors.

If you want a higher quality photographic image, choosing the higher number of pixels provided by a 4K camera is the better choice, though image quality is influenced by other factors including the quality of the camera's sensor, lens, and image processing algorithms.

If you’re looking for a 4K security camera, the Argus PT Ultra is an excellent choice.

How many pixels in a 4K monitor?

4K monitors have the same number of pixels as 4K televisions and cameras, but the impact of pixel count on a monitor’s display will vary based on other factors, including screen size and viewing distance. Larger monitors tend to benefit more from higher pixel counts, as the increased resolution is more apparent.


1. How many pixels are in UHD?

Ultra High Definition (UHD) refers to a resolution frequently used for displays and video content. The pixel count for UHD resolution is 3840 pixels horizontally by 2160 pixels vertically, and is also referred to as 2160p or 4K resolution.

2. How many pixels are there per inch?

The number of pixels per inch (PPI) varies depending on both resolution and the size of the display. PPI is a measure of pixel density and indicates how many pixels are packed into each inch of the screen. For example, the PPI calculation for a 27-inch 4K UHD monitor would be:

PPI = (Square root of (3840^2 + 2160^2)) / 27

3. How many pixels in a 55-inch display?

The number of pixels in a 55-inch display will vary based on its resolution. Common resolutions include Full HD (2.1 million pixels), 4K UHD (8.3 million pixels), and 8K UHD (33.2 million pixels). Higher resolutions will provide more detail and clarity in the displayed content.

4. Is 2160p the same as 4K?

Yes, 2160p is commonly referred to as 4K resolution. The "2160" in 2160p represents the number of vertical pixels. In the context of video and display resolutions, "4K" generally refers to a horizontal pixel count of approximately 4000 pixels.

5. What are the differences between pixels and megapixels?

Pixels are the smallest units of a digital image. They each represent a single point of color or light intensity and are used to describe display resolution.

By contrast, the term megapixels refers to one million individual pixels, and is used to describe the resolution or image quality of digital cameras. The megapixel quantity indicates the total number of pixels captured by the camera's image sensor, while the number of pixels determines the level of detail and sharpness in an image or video.


4K resolution has revolutionized the way we experience visual content. With their impressive pixel count, 4K displays offer unparalleled clarity and detail, bringing even the smallest elements of an image or video to life. Whether you are gauging the quality of a camera or a visual display, understanding pixel count is crucial to ensuring the best viewing experience.
