test card
Screen calibration image
A test card is a static image broadcast by television stations, used to calibrate picture quality on screens.
The geometric patterns, color bars, and reference shapes help technicians adjust brightness, contrast, and color accuracy.
Test cards were once familiar during off-air hours; now they appear mainly for technical setup.
Also called a test pattern.
