According to DisplayMate, the iPhone X has the "most innovative and high performance" smartphone display it has ever tested. DisplayMate also congratulated Samsung Display for "developing and manufacturing the outstanding OLED display hardware in the iPhone X." iPhone X matched or set new smartphone display records in the following categories: highest absolute color accuracy, highest full screen brightness for OLED smartphones, highest full screen contrast rating in ambient light, and highest contrast ratio. It also had the lowest screen reflectance and smallest brightness variation with a viewing angle. The iPhone X's 5.8-inch OLED display includes a taller height to width aspect ratio of 19.5:9, 22 percent larger than the 16:9 aspect ratio on previous iPhone models (and most other smartphones).
Because of this DisplayMate noted that the iPhone X also has a new 2.5K higher resolution with 2436x1125 pixels and 458 pixels per inch. The iPhone X's display resolution provides "significantly higher image sharpness" than can be analyzed by a person with normal 20/20 vision at a 12-inch viewing distance. DisplayMate said this means that it's now "absolutely pointless" to increase the display resolution and pixels per inch of the iPhone any further, since there would be "no visual benefit" for users.
