Input Lag Breakdown: Display Scaler Processing Delay vs Panel Scanout: Advanced Implementation and Real-World Architecture

[Alex Allen]

The way the scaler processes the frame before scanout always trips me up when I’m chasing every single millisecond of input lag in competitive

Great topic—most people lump “input lag” into one number, but separating scaler delay from scanout is where the real story is. The scaler processing delay is basically the time the display’s image processor spends on the incoming signal before it hands off to the panel: de-noising, color calibration, dynamic contrast, upscaling, and any frame interpolation. In “Standard” or “Movie” modes this
