[ProArt StudioBook] Delta E Introduction

What is Delta E?

Delta E (dE) measures the amount of change in visual perception of two colors. This measurement provides valuable insight into how color accurate a display, like a PC monitor is. The average person won’t notice a Delta E error that’s less than 3.

However, the trained eye can see down to errors of 1, while errors less than 1 are usually considered imperceptible. Top monitors achieve a Delta E of 2, where the color difference is barely detectable.

Why Does Delta E Matter?
When we compare monitors, the lowest average Delta E is favored. Lower average Delta E values mean more accurate grayscale tracking and color.

Accurate color reproduction on a monitor is especially essential for creative professionals, who need to make sure that the colors they see on their screen are as true-to-life as possible. With a lower Delta E value, input, like from a camera, will be more accurate. It’s also helpful for those using multiple monitors.

Delta E values matter the most to professionals and creatives dependent on color accuracy. But whether you’re an artist or just a dedicated gamer or someone who wants the most out of their monitor, Delta E values (like the ones we use in our monitor reviews) give you a better idea of a monitor’s accuracy.

Delta-E < 1.5 color accuracy
More accurate color through Color calibration technology for perfect colors
Color calibration technology adjusts display color and settings. In addition, the low Delta-E value ensures more accurate colors.


For ASUS ProArt StudioBook, color accuracy Delta-E is low as below shown.

The following are the average data measured from factory. (different instrument may get different result)
