In a factory setup, there is one measurement device per production line, and there are usually more than one production line. Even though the measurement devices are calibrated carefully before each use, there are still discrepancies and would result in different visual appearance. As a result, when a user purchase two or more units of the same model, the units may not look alike when they are turned on. With BenQ’s proprietary Color Consistency Technology, the measurement devices are aligned, and the units calibrated will looked alike. So users do not need to worry if the units will not look the same visually. Ultimately, for SW and PV series monitors, we even offer hardware calibration functionality. If at a later stage when factory calibration result started to drift, hardware calibration function can offer the color accuracy which meets the industrial standards with your calibrator of your choice.
