Galaxy S8 Display Earns DisplayMate’s Highest-Ever A+ Grade

DisplayMate Technologies has released the results of its comprehensive evaluation of the Infinity Display found on the Galaxy S8, concluding that Samsung’s new flagship possesses “the best-performing smartphone display that we have ever tested.” The Galaxy S8 smartphone is the latest Galaxy device to secure high praise from DisplayMate – earning its highest-ever A+ grade.

The report, drafted by DisplayMate President Dr. Raymond M. Soneira, provides a detailed summary of the enhancements responsible for the devices’ unsurpassed visual experience.

The Galaxy S8 earned top marks thanks to the record-setting specs of its curved, full-screen OLED display, which nearly fills the entire front of the smartphone from edge to edge. In order to provide more screen space, the home button has been incorporated within the screen itself, which measures 5.8 inches in the Galaxy S8 and 6.2 inches in the other new Galaxy flagship, the S8+, with an 18.5:9 aspect ratio for each that adds significantly to the viewing experience.

Video content is even more vivid and engaging thanks to the Galaxy S8 and S8+’s new ‘Deep Red’ OLED, which provides significantly higher color saturation. This creates a larger native color gamut – measuring 113 percent of DCI-P3 and 142 percent of sRGB/Rec. 709* in the Galaxy S8 – the highest DisplayMate has ever measured in a smartphone or tablet – which allows the screen to portray high-definition content with exceptional accuracy.  The new 3K (2960 x 1440), 570 pixel-per-inch Quad HD+ display features the highest resolution currently available in a smartphone with an OLED screen, and produces crystal clear images under all typical viewing conditions. In fact, the Galaxy S8 is also the first smartphone to receive the UHD Alliance’s ‘Mobile HDR Premium’ certification, which attests the screen’s ability to bring the most advanced HDR content to life.

This is possible in part due to the display’s peak brightness, which amounts to, as Dr. Soneira noted, “the brightest smartphone display that we have ever measured.” The Galaxy S8 produces clear viewing under high ambient light conditions (up to 1020 nits) – such as in bright sunlight – and delivers a screen reflectance of just 4.5 percent, which ranks among the lowest that DisplayMate has ever observed. In addition, the screen’s combination of high brightness and low reflectance equate to an ambient light contrast rating of 227 – “the highest that we have ever measured for any smartphone display.” The Galaxy S8 and S8+ are available in the U.S. beginning April 21st.


*Editor’s note: The Galaxy S8 features four screen modes calibrated for different content, applications and user preferences. These measurements reflect the devices’ default screen mode, ‘Adaptive Display’.
