About 1:1 pixel mapping

Q1: What is 1:1 Pixel Mapping?

A1: 1:1 Pixel Mapping is the process where each pixel of the input source is accurately represented by a pixel on the display. This method ensures maximum sharpness and pixel precision as it avoids any kind of pixel stretching, compression or averaging.


Q2: How is 1:1 Pixel Mapping reflected in a video wall controller?

A2: In a video wall controller, 1:1 Pixel Mapping is reflected in the way input sources are distributed across the display panels. If the controller supports 1:1 Pixel Mapping, it means that each pixel of the input signal is mapped directly onto a pixel of the video wall. This guarantees that the image displayed on the video wall is an exact representation of the original image without any loss in resolution or detail.


Q3: What are the benefits of a video wall controller that can implement 1:1 Pixel Mapping?

A3: The main advantage of a video wall controller that supports 1:1 Pixel Mapping is the improvement in image quality. Since each pixel of the input source is directly represented on the display, it results in an accurate and sharp representation of the original image. This eliminates any potential pixel distortion, loss of resolution or degradation in image quality which could occur due to pixel stretching or compression. It's particularly beneficial for high-resolution and detailed images, as it ensures optimal visual quality.


Q4: Why do ultra-high-resolution video wall solutions need to choose 1:1 Pixel Mapping devices?

A4: Ultra-high-resolution video walls require 1:1 Pixel Mapping devices to ensure the quality of the displayed images. Given the high resolution of these video walls, any distortion or loss of resolution can significantly impact the viewing experience. By using 1:1 Pixel Mapping, each pixel from the input source is accurately displayed on the video wall, ensuring the best possible image quality. It also allows the video wall to fully leverage its ultra-high-resolution capabilities, providing a more immersive and detailed viewing experience.


Q5: What is the difference between a 1:1 Pixel Mapping display solution's video wall controller and a proportional stretching solution's video wall controller?

A5: A 1:1 Pixel Mapping video wall controller preserves the original resolution of the input source by mapping each pixel to a corresponding pixel on the display, ensuring image quality and detail. This results in a clear, sharp and distortion-free image.

On the other hand, a proportional stretching solution's video wall controller changes the aspect ratio of the input source to match the display. This can lead to image distortion or loss of resolution, as pixels may be stretched, compressed, or even discarded to fit the display. Although the image may fill the entire display, the trade-off is often a loss in image quality and precision.


Q6: If we choose non-standard 16:9 monitors as output, why should we opt for a video wall controller with customizable resolution?

A6: Choosing a video wall controller with customizable resolution offers flexibility and optimization when dealing with non-standard 16:9 monitors. This is because it allows you to precisely tailor the output to match the specific resolution and aspect ratio of the display. By doing this, you can avoid image distortion, pixel stretching or compression that can occur when trying to fit a standard resolution image onto a non-standard display. This results in better image quality and a more accurate representation of the original source.
