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.
