Pink Screen
Display a full-screen pink color. Useful for checking screen uniformity, dead pixels, backlight bleed, and color accuracy on pink backgrounds.
Uses for pink screen
Dead pixel detection: look for pixels that do not display pink correctly.
Screen uniformity: check for uneven brightness or color patches.
Backlight bleed: especially visible on dark and solid color screens (LCD).
Color accuracy: compare how pink looks versus reference images.
Testing guide
What a full pink screen reveals
Pink and magenta are produced by red and blue together with green switched off. Because green normally carries most of the perceived brightness, removing it entirely makes any green sub-pixel that is stuck on impossible to miss, and it stresses the two channels the eye is least sensitive to.
Best for
- Catching stuck green sub-pixels, which show as bright dots against the pink field.
- Checking that red and blue render evenly together without a color cast.
- Testing wide-gamut panels, since saturated magenta sits near the edge of sRGB.
How to run the test
- 1Run the pink fill fullscreen on a clean panel.
- 2Scan for any green, cyan, or white dots, which indicate green sub-pixels stuck on.
- 3Check whether the pink stays consistent or drifts toward red or purple across the surface.
- 4Compare with the red and blue fills to identify which channel causes any unevenness.
How to read the result
A green or white dot on pink is a stuck green sub-pixel, which is the hardest type to spot on ordinary content.
Pink drifting toward purple means blue dominates; drifting toward red means blue output is weak.
On a wide-gamut display, magenta may look noticeably more intense than on an sRGB panel, which is expected rather than a fault.

Frequently asked questions
What is the difference between pink and magenta on a display?
Magenta is the full-intensity mix of red and blue with green off. Pink is the same hue at lower saturation, achieved by adding some green back or reducing overall intensity. Both are useful for isolating the green channel.
Why is a pink screen good for finding stuck green pixels?
Green is switched off across the entire panel, so a pixel with a stuck green sub-pixel becomes the only green light on screen. Since green is also the channel your eye is most sensitive to, it stands out sharply.
Why does my whole screen look pink or magenta?
A screen-wide pink cast usually means the green channel has failed or is being underdriven, often caused by a damaged cable, a bent connector pin, or a failing panel driver. Try a different cable and port before assuming the panel is at fault.
Does pink stress the panel more than other colors?
It drives red and blue at full intensity while leaving green idle. On OLED that means the blue emitters, which are the shortest-lived, are working hard, so it is not a color to leave on screen for long periods.
Is magenta a good test for wide gamut displays?
Yes. Saturated magenta sits close to the boundary of sRGB, so a wide-gamut panel renders it noticeably more vivid than a standard one. It is a quick way to see whether a display really exceeds sRGB.
