LED screens for outdoor advertising have become an essential tool for businesses to promote their products and services. However, choosing the right resolution for each screen size is crucial to ensure that advertising has the desired impact. In this blog post, we will explain how to choose the right resolution for different sizes of digital signage screens.
The resolution of an LED screen refers to the number of pixels on each axis, horizontal and vertical. The higher the resolution, the better the image quality and the more detail can be seen on the screen. Resolution is measured in pixels and represented by two numbers, the first referring to the number of pixels on the horizontal axis and the second to the number of pixels on the vertical axis.
To choose the appropriate resolution for each screen size, it is crucial to consider the distance at which the screen will be viewed and its size. Below, we explain how to do it:
For small screens, such as those used in shop windows or indoors, a Full HD resolution of 1920×1080 is usually sufficient. This is because the distance at which the screen will be viewed is shorter, so a very high resolution is not necessary. However, if text or images with a lot of detail are to be used, it is recommended to increase the resolution to 2560×1440 (Quad HD) or even 3840×2160 (4K), so that the content can be seen with greater clarity.
For medium screens, such as those used in billboards or building facades, a higher resolution of 2560×1440 (Quad HD) is suitable for screens up to 6 meters away. For screens more than 6 meters away, a resolution of 3840×2160 (4K) is recommended so that the content can be seen clearly, even at long distances.
Large screens, such as those used in stadiums or massive events, require an even higher resolution. In this case, a resolution of 5120×2880 (5K) or 7680×4320 (8K) is recommended to clear the content even at long distances.
It is important to note that resolution is not everything: the quality of the screen, brightness, and contrast are also essential for achieving an effective advertising campaign.
