The resolution of an LED screen is a factor to consider when we are about to buy one of these devices. Beyond the size, because the dimensions do not necessarily mean that it is a good choice.

It is a feature that will provide greater comfort and efficiency when projecting images or videos, especially if it is a screen that will be used for a business or meeting place.

In this article, we’ll take a look at what to consider whenever looking for the right resolution for a large LED display.

Understanding screen resolution: what it means and how it impacts image quality.

Despite what you may think to the contrary, the highest resolution is not always the best. The distance you will keep when viewing it and the amount of detail you are looking for are two elements to consider in this choice of the best LED screen.

If you have a 40-inch screen and you’re eight feet away, there’s no way the human eye can tell the difference between 720p and 1080p resolution. It is the same thing that happens with the Full HD resolution, which only makes sense for a screen of 60′ inches and above due to the large amount of detail that it must show.

Regarding these values ​​(720p or 1080p) it has to do with the amount of pixels that occupy the screen. Each pixel lights up to compose an image, a range of colors or letters.

The resolution for led video walls

The resolution usually looks like this:

680 x 720p, which is SD resolution, for small screens up to 20′.
1920 x 1080p, also known as HD or High Definition.
980 x 1024p, standard resolution for office or home displays and monitors.

This is why high resolutions require larger screens to cover the number of pixels needed.

There is an additional, very important feature, which is the pixel size, and it is largely related to the quality of the projected image. It is possible to find these different pixel sizes:

  • P1.9.
  • P2.5.
  • P3.91.
  • P5.

These values ​​may seem strange on their own, but it is a relationship to the distance you can find between each of the small bulbs that make up an LED.

When in the description of the equipment, you find something similar to P1.9, it means that there is a distance of 1.9 millimeters (P2.5, is equal to 2.5 mm and so on). Which translates into greater precision of the lines and details or depth in the color palette.

Considering the above, it is necessary to choose knowing the usual distance in which the screen is going to be seen.

For less than 8 feet away, you can go for a standard resolution (1080p) display, unless you want supreme quality, need a lot of detail, or have the display readable from greater distances, then a higher screen resolution.

Let’s see the pixel pitch and the minimun distance relationship:

  • P1.99mm distance of 5 feet.
  • P2.6mm distance of 6 ft.
  • P2.97mm distance of 6 ft.
  • P3.91mm distance of 8 ft.
  • P5mm distance of 16 ft.

Matching the resolution to the content displayed 

Now, how do you know what resolution is suitable for the content you are going to display? Let’s see,

  • If it is about text, the best choice is a standard screen, not very large and with a 720p resolution, since we can enlarge the text so that it is easy to read. The same if they are slide images or simple ones.
  • On the other hand, in the case of images, it is vital to opt for a large, high-resolution screen, because it will allow you to obtain a greater amount of detail, both colours, depth and, obviously, greater sharpness.
  • Remember that it is important to configure the screen to get the most out of the resolution.
  • Finally, be sure to do a test to make sure the content looks good on the screen.

Best practices for testing and evaluating different resolution options

To understand, let’s use a practical case:

A marketing team in Florida needs to install an LED display at the entrance of a shopping center.

This is the main flow of potential customers, so the goal is to promote the largest number of products and services, as well as improve the customer experience. That is why it is useful for placing maps, new releases and offers.

This team opted for the greatest possible efficiency, so they decided to purchase a giant, high-resolution screen, although they first had to define the type of content to be projected on said device.

They also determined how far away the target audience would be, and finally ran tests to confirm the visual quality of each resolution. In this evaluation they reviewed sharpness, color accuracy, contrast, and aspect ratio.

With these practices, they managed to meet the objectives of the campaign implemented in the shopping center, later this translated into an increase in sales throughout the establishment.
