Huawei Mate 9 released at the end of last year, we did not intend to test this smartphone, but thanks to a young wealthy reader providing one for us. Huawei Mate 9 adopts a 5.9-inch IPS FHD display. Who is the display screen provider? Mr. Yu Chengdong (Richard Yu), CEO of the Huawei Consumer BG, revealed that JDI, Sharp and LG are providing.
As a flagship, the fact that Mate 9 insists a FHD display is a little disappointing, as it is a flagship model. By now, QHD AMOLED/IPS-TFT displays are popular among hi-end Android smartphones. A 5.9-inch FHD display still owns 371 PPI, which is still acceptable. Huawei retains the better 5.5-inch QHD edge-curved AMOLED display to the latter Mate 9 Pro, which we are testing now.
Except the hardware, the internal color management also influences the display directly. Color accuracy and luminance accuracy, each stands for the ability to display standard color gamut and right value for every color throughout its entire color space, are the majority testing standards for display. By now, only Samsung, Apple and Microsoft are providing refined color management in their flagship models, Huawei is not included. Mate 9 runs on EUI system based on Android 7.0, and it provides settings to modify color temperature and tone for users to adjust to their flavor. Also, Mate 9 provides eye comfort mode for text reading and night using, just like Huawei P9. The ¡°Increase Readability in Sunlight¡± was tucked away under Developer Options.

From our quantitative result, Mate 9 has a similar display performance with LG G5 SE, while G5 SE has a higher QHD resolution display. They also share the same problem, for example, their default color temperature is similar, a little cold, over 7800K, which affected their color and luminance accuracy result in 6500K. They also have larger color gamuts, larger than the widely-used sRGB, Mate 9 reaches 125 percent of the sRGB color gamut, closer to the DCI-P3 wide color gamut. However, the colors on Mate 9 are over saturated when viewing pictures online, and we felt some crashing when using some warm-color Apps. We tested Huawei P9 in our Chinese website, some readers are doubting if adjusting the setting could optimize the display performance to make the color and luminance more accurate. However, we cannot find such a point.
To further illustrate, we will compare Mate 9 and P9¡¯s Gamma 2.2 graph in default, warm, and manual adjusting. In ideal display Gamma curve, the red, green and blue curve should keep coincident and in the middle, if any curve deviants, that stands for the color trend of the display screen. We can find a coordinate in P9 to match the Gamma 2.2 graph, and the color and luminance accuracy is also better at that point. However, we cannot find such a coordinate in Mate 9, if you can find one, please contact us, we will complement this review.
OK, after glanced the color performance of Mate 9, we believe you are more concerning about the experience in daily use. Mate 9 enhances its maximum luminance compared with Huawei P9, from 420cd/m2 to 560cd/m2, which helps it with visibility to use outdoors in sunlight, whether viewing websites or taking photos. If you upgrade from P9 or Mate 8, you should be satisfied with this max luminance performance.
