Black Shark 4 uses the latest generation E4 AMOLED from Samsung for its gorgeous yet power-
saving display.
It features ultra-narrow edge with peak brightness of 1500nits, global maximum brightness of
900nits, a contrast ratio of 5000000:1, and a 15% reduction in power consumption. The front
camera micro-hole measures only 2.76mm to minimize screen obstruction, creating a more
integrated look and an immersive gaming experience. The visual perception during gaming is
better integrated, and the screen supports True DC dimming to protect the eyes during prolonged
use. The screen has been built to handle even the most challenging graphics and is HDR 10+
certified.
Black Shark 4 offers a high refresh rate of 144Hz which intelligently adapts to the 144Hz refresh
rate of the latest games to provide players with silky smooth gaming experience. Users can also
select from three custom refresh rates of 120Hz, 90Hz, and 60Hz to achieve the appropriate screen
refresh rate accordingly to suit their preference and the application requirements to achieve
smoother graphics.
We implement full symmetry ultra-large amplitude dual linear speakers, top circuit sounding unit,
and a large sound cavity for the dual speakers.
Besides professional tuning and algorithms are required to give these units full play. We adopt the
industry’s top software and hardware audio algorithms, including DTS, ELEVOC, and Cirrus
Logic technologies. Based on these technologies, we independently develop our unique Biso sound
effects.
