Flicker (Parpadeo)

Variaciones muy rápidas en la intensidad de la imagen causadas por el tiempo finito requerido para que el haz de electrones explore cada línea de imagen de la pantalla. Se producen dos clases de parpadeo: de línea, producido durante el barrido de cada una de las líneas de la imagen, y de imagen (o de campo, en modo entrelazado), originado por la velocidad de repetición de

50 imágenes por segundo. El parpadeo de imagen (o cuadro) se pone de manifiesto en las aplicaciones GUI y DTP (con fondo iluminado), y puede resultar molesto para las personas que trabajan normalmente con imágenes, provocando fatiga visual, dolor de cabeza, visión borrosa, tensión, etc. No obstante, el problema se puede resolver elevando la velocidad de refresco (imágenes por segundo) del monitor a un valor por encima de 70 Hz. La sensibilidad al parpadeo disminuye con la edad.

Hertz (Hercio o Hertz)

Unidad de frecuencia que debe su nombre al físico Heinrich Hertz (1857-1894). 1 hercio (Hz) equivale a 1 ciclo/segundo.

Horizontal dot pitch (Tamaño de punto horizontal)

Véase Tamaño de punto.

Horizontal scanning frequency (Frecuencia de exploración horizontal)

También se conoce como frecuencia lineal y se expresa en kHz. Es el número de líneas de imagen impresionadas sobre la pantalla cada segundo (de izquierda a derecha). Cuanto más alta es la frecuencia de exploración horizontal, mejor es la resolución (es decir, más alta es la resolución o mayor la velocidad de refresco).
