Eliminate Eye Strain in Any Ambient Light
Brightness Intelligence Technology (B.I.Tech.) monitors ambient light in your viewing environment and actively adjusts screen brightness for the most comfortable viewing experience possible.

Low Blue Light Technology
The unique BenQ Low Blue Light Technology is designed to filter out harmful blue light, effectively diminishing eye fatigue and irritation.

Flicker-free
Flicker-free eliminates flickering at all brightness levels and reduces eye fatigue effectively. Conventional LCD screens flicker at the rate of 250 times per second. Your eyes may not see the flickers but they can certainly feel them. So relieve your eyes from the uncomfortable flickering effect by switching to a BenQ flicker-free monitor.

Color Weakness Mode
BenQ�s Color Weakness mode allows users to customize the amount of red or green displayed on the monitor with magenta and cyan filters. Once the red and green are neutralized, the mode ensures a comfortable viewing experience for all users and helps users to clearly distinguish between different colors. Additionally, BenQ�s color weakness mode also helps improve the viewing experience for people with red or green color deficiency while allowing users to adjust the level of color weakness mode.
