Refresh rate
How many times per second the LEDs are re-driven — 1,920 to 7,680 Hz on professional walls.
LED refresh rate is how often the drive electronics rewrite the image on the LEDs — thousands of times per second, independent of the 50/60 Hz video frame rate. Low refresh shows as dark banding on cameras.
1,920 Hz is entry level, 3,840 Hz the broadcast norm, and 7,680 Hz appears on premium and film-oriented (virtual production) products. For walls that will be filmed, refresh rate matters more than almost any optical spec.
