While Apple did not disclose details about its displays on the iPhone XS and XS Max, DisplayMate conducted rigorous testing to find out how the new Super Retina OLED display works. The XS Max received the highest A + rating that DisplayMate has ever awarded and has earned the Best Smartphone Display Award. The “absolute color accuracy” of the iPhone XS is described as “truly impressive”, reaching 0.8 JNCD (barely noticeable color difference) for sRGB / Red.09 color gamut, which is used for most content, and 0.8 JNCD again for the wider DCI-P3 color gamut used by 4K TVs and digital cinema. Both results are classified in the report as “visually indistinguishable from reality” and are likely to be better than most monitors, televisions and other devices on the market. The screen is very bright and has a low reflection coefficient, which makes it extremely useful for readability, image quality and color accuracy in daylight. In the case of the iPhone XS Max, it has a record high calibrated 100 percent brightness of the APL screen of 660 nits for sRGB and DCI-P3 colors (for iPhone X, this figure is 634 cd / m2). The reflection coefficient of the display is 4.7%, which is close to the most the lowest ever measured when testing a smartphone. Combined with screen brightness, it achieved a contrast ratio of 139 to 164, which is the highest in testing. In all but two tests, the iPhone XS Max display reached the highest levels, with green (very good and excellent) ratings. Two are yellow (good) in terms of performance: the smallest change in brightness with a change in viewing angle of 6.2 JNCD and a 15 percent change in brightness with an average level of image. The iPhone XS and Max can be used in wet rooms and outdoors thanks to stronger protection against water and dust, which corresponds to the IP68 class compared to IP67 in the iPhone X. And with a more durable and scratch-resistant cover glass, the new iPhones provide better resistance to breakage than previous models X, 8 and 8 Plus. While 6.4- Samsung Galaxy N inch OLED display ote 9 also received an A + rating, the Apple iPhone XS Max scored more points with its nearly flawless display. The DisplayMate test was conducted with the iPhone XS Max, but most of the results apply to the 5.8-inch iPhone XS.
