Blue tint screen
Left half is true white, right half is the cast people describe. Which one does your screen look like on the full-screen white test?
Plain colours, full screen:
A screen screen that has gone blue all over is the signal or the panel's colour balance, and it is usually the signal.
Test it now
Full-screen white. If white looks blue, take a screenshot and open it on another device: a tint that is in the screenshot is software. Plug in an external monitor: a tint that appears there too is the graphics driver, not the screen. Tilt the lid: a tint that changes is the cable.
What it is
A screen screen that has gone blue all over is the signal or the panel's colour balance, and it is usually the signal. Night Light / Eye comfort / a colour filter, a wrong colour profile, or a graphics driver fault tint the whole image; a display cable that has lost one of its colour channels tints it too (blue = the red channel is missing, or a cold colour profile); the panel itself tints only when its backlight LEDs age (a warm yellow) or its polariser degrades.
Can it be fixed?
Settings, profile, driver: yes, free — turn off Night Light / colour filters, reset the colour profile, reinstall the graphics driver. Cable: yes, a small repair. Backlight or polariser ageing: no — new panel, or live with it.
What to do
- Night Light off, colour filter off, colour profile reset to default.
- Screenshot and external monitor: tint on both = graphics driver; reinstall it.
- Lid tilt changes it: cable — small repair.
- None of those: panel; decide between a panel and a new screen.

Warranty
Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).
