A scaler is a specialized electronic circuit that adjusts the resolution of an incoming video signal to match the native resolution of a display. Scaling can be performed up or down by adding or reducing pixels while preserving image quality. Scalers are essential when the input signal (from a PC, camera, or media player) does not match the panel’s resolution. Advanced scalers can also perform aspect ratio adjustments, noise reduction, color correction, and analog-to-digital conversion. They are widely used in monitors, TVs, operator panels, and digital signage systems.
