Raster and vector displays differ significantly in their maintenance requirements due to their underlying technologies. Raster displays, which rely on pixel grids, often require frequent calibration to prevent color inaccuracies and screen burn-in. Their fixed resolution means degraded pixels can visibly impact performance, necessitating timely replacements.

Vector displays, on the other hand, use mathematical equations to render images, eliminating pixel-related wear. However, their analog components, such as CRT deflection coils, may degrade over time, requiring occasional recalibration. Unlike raster screens, vector displays are less prone to burn-in but may suffer from phosphor decay.

Key maintenance differences include:

- Resolution Handling: Raster displays need regular checks for dead pixels, while vector displays focus on signal integrity.

- Hardware Wear: Raster screens face backlight degradation; vector screens require cathode-ray tube upkeep.

- Calibration: Raster displays demand color calibration, whereas vector displays need geometric alignment.

Understanding these distinctions ensures optimal longevity and performance for each display type.
