¿Por qué usar una pantalla Yellow?
Warm fill light
Yellow provides soft, warm illumination for video calls and photography.
Dual-channel test
Yellow activates red and green subpixels together — catches issues single-channel tests miss.
Banding detection
Gradient-free yellow helps reveal color banding on some panels.
Yellow for mixed-channel testing
Because yellow requires both red and green at full intensity, a faulty green or red subpixel may create visible artifacts.
Warm white points on many monitors lean yellow — compare yellow fullscreen to white to assess color temperature.
