Using a pink screen during display testing can help expose issues like uneven backlighting, screen tinting, or chromatic aberrations that may not be noticeable with primary color tests. The pink hue can reveal color shifts or inconsistencies, especially along the corners or sides of the screen. For OLED or high-end LCD displays, this kind of test ensures that the device meets expected standards of visual performance, helping manufacturers identify and rectify defects before reaching consumers.https://testmydisplay.com/pink-screen/
