What Is 4K Resolution and How Does It Compare?

    4K Ultra HD technology is gaining popularity, and televisions, gadgets and computers are starting to feature this higher pixel resolution.

    Content creators are also embracing 4K, and we can now view a selection of sports, movies and television shows in crystal-clear quality. You may be wondering whether or not it is worth upgrading to 4K Ultra HD. Is it just a buzz word to increase sales, or is it actually going to make a difference? To get the answer to these questions, let’s take a look at some of the more common resolution types.

    720p Resolution

    When we talk about resolution, it refers to the number of pixels on a screen. If you look at your monitor, the display is made up of tiny dots called pixels. The resolution will only give you a limited number of pixels, and if they have to stretch to fit a bigger screen, it can result in poor picture quality.

    This resolution might be fine for a small TV, but would look distorted on a bigger screen. The resolution for this is 1,280 height x 720 width, which equals 921,600 pixels. This is still classed as HD.

    1080p Resolution

    The next step up from 720p is 1080p. This is called Full HD and has more than twice as many pixels as HD. The resolution is 1,920 height x 1,080 width, which equals 2,073,600 pixels. As you can see by the numbers, this is significantly better than the previous HD standard.

    Before 4K technology hit the market, Full HD was the most common choice for those looking for a high-definition solution. Most games and television shows have been made with this in mind and it will still give you a decent picture. However, with screen sizes getting bigger, anything over 40 inches will benefit from 4K.

    4K Resolution

    Then we have 4K. This technology has become more affordable, and consumers are opting for this over other resolutions. This has a total of 8,294,400 pixels, which is about four times that of the 1080p making it ideal for a big screen. The clarity and picture quality is going to give you crisp video, and with compatible programs, you will be able to see every detail, including the wrinkles on the actors’ faces.

    It isn’t just televisions that are utilizing this type of technology. You can now purchase security camera systems with 4K capabilities. These can record footage in Ultra HD, and this can be viewed by police if required. Imagine being able to capture a criminal in action, complete with any identifying features.

    Beyond 4K

    There is one other resolution you may have heard of, and that is 8K. While this does sound like a great option, it will be a long time before you will be able to use it to its full potential. Right now, 4K is gaining momentum and it is probably going to give you more value for money.

    While 1080p is still reasonable, 720p is an older standard and probably won’t give you the results you expect in this digital world. For those looking to install a security camera system, consider 4K for a clearer picture and clarity.
