Full-Array Local Dimming on Vizio V555-H11

Vizio V555-H11 has Full-Array Local Dimming technology with multiple zones throughout the display. Individual zones of LEDs can light up independently which enhances black levels, shadow details and decreases level of light bleed in dark parts of the image.

Higher number of zones gives better control over local dimming and less blooming around the bright objects and subtitles.
