The sharp detail and vivid colors from each and every BenQ LCD panel is made up of tiny pixels, and each tiny pixel has three smaller individual red, green and blue pixel. Thus, a single BenQ LCD panel consists of millions of tiny pixels.
During LCD panel manufacturing of BenQ LCD monitors, digital signage or interactive display product, it is not uncommon for pixels to remain "stuck", a phenomenon which an imperfection either a colored pixel which is always ON (bright), or always OFF (dark). This is considered normal and does not affect the overall performance of BenQ display.

Should the LCD panel is diagnosed to contain or exceeding the following number of non-conforming pixel (dot) within the duration of Warranty period, the LCD panel is then considered as a defect and can be claimed as Warranty service.
