Is 1080p 2K or 4K?

To answer the question, let’s first clarify what 1080p, 2K, and 4K actually mean.

1080p, also known as Full HD, refers to a display resolution of 1920×1080 pixels. The “p” stands for progressive scan, which means that all lines of the image are displayed sequentially, resulting in a smoother and more detailed picture compared to interlaced scan methods. This resolution is commonly used in TVs, computer monitors, and other display devices.

On the other hand, 2K is a resolution commonly used in the cinema industry. It refers to a resolution of 2048×1080 pixels, with the “K” representing the approximate number of horizontal pixels. It is slightly wider than the 1080p resolution commonly used for TVs. 2K resolution provides a higher level of detail and clarity, which is especially important in large cinema screens.

Now, the question arises: Is 1080p considered 2K or 4K? The answer is neither. While 1080p and 2K resolutions have similar vertical resolutions (1080 vs. 1080), they differ in terms of horizontal resolution (1920 vs. 2048). Therefore, they are distinct resolutions and cannot be considered the same.

Furthermore, it is important to note that 4K refers to a resolution of 3840×2160 pixels, also known as Ultra HD. This resolution provides four times the number of pixels compared to 1080p, resulting in incredibly sharp and detailed images. 4K is currently the highest resolution available for consumer displays and offers a significant improvement in picture quality.
