Acer's Predator X27 portrays astonishingly vibrant visuals without motion blur thanks to a high 4K (3840x2160) resolution at a 144 Hz refresh rate, a fast 4 ms response time and a 1,000 nit peak brightness. Featuring Acer HDR Ultra technology, it offers the best possible contrast quality of the high dynamic range with advanced LED local dimming in 384 individually-controlled zones that shine light only when and where it is required. It not only delivers a broader, more deeply saturated color gamut, but a luminance range several times greater than that of traditional dynamic range monitors.
