resolution. Whether working on the next beautiful photo, design, or
even just for productivity, users will appreciate the true crisp imag e
from a UHD display.

spreadsheets or weekend movies from virtually any angle without
compromising color uniformity.

Immersive Visual Experience
Human eyes are not flat and perceive the world around us in
angles and curves. Curved monitors deliver the best viewable
angles that allow users to see more. Aside from the appeal of an
immersive gaming or work environment, there’s a benefit in
reduced eyestrain from a consistent radius between your eye
and the
AOC SuperColor Technology
This curved 4K monitor has larg er co lor gamut, which means larger
range of the wide-ga mut RGB color space the monitor is able to
display. A typical monitor has only 7 2 % N TSC color gamu t , whereas
the C4008VU8 boasts an incredible 85% NTSC wide color gamut for
rich vivid colors.
Flicker-Free Technology for Reduced Eye Fatigue
The normal LED-backlit monitors adjust brightness us ing PWM
(Pulse Width Modulati on). This causes flicker al t hough human eye s
can’t see it easily, it still causes discomfort over long periods of
time. Flicker-free technology is using DC (Direct Current) backlight
system to provide more comfortable and healthy viewing.
