Coverage is rated at 130% of the sRGB space and 95% of DCI-P3. Also noteworthy is the eye safety certification (TÜV Rheinland) and a solid brightness reserve, up to 450 nits + compliance with the DisplayHDR 400 standard. Specifically for gaming, the model offers a fast response time of 1 ms, a refresh rate of 160 Hz, adaptive synchronization with AMD FreeSync Premium, and a plethora of profile options, including an aiming reticle and highlight feature (implemented via AI algorithms).
