DisplayMate's success is the result of developing the most challenging and sensitive test patterns in existence for displays. Unlike traditional test pattern generators that produce a small number of bland, generic, multi-purpose test patterns that were developed primarily in the 1950s, DisplayMate pioneered the development of proprietary, special purpose analytical test patterns that individually examine each display parameter at the highest possible sensitivity. Each test pattern is carefully fine-tuned for the maximum possible effect and a set of such patterns is viewed in a programmed sequence. The result is that DisplayMate produces the most powerful and revealing test patterns. They show effects and differences between displays that go unnoticed using all other methods. That is the reason why DisplayMate has become the standard for evaluating image and picture quality and why journalists depend on it for producing the best reviews and comparisons.
