What it is
A white dots on a computer screen that glows on black is the backlight coming through where it should not: the reflector or diffuser sheet behind the LCD has a pressure dent, or a backlight LED sits too close to the panel. It is bright and slightly fuzzy-edged, and it is strongest on dark screens.
Can it be fixed?
Backlight pressure point: sometimes — on a phone or tablet a repair shop can open the display and flatten or replace the reflector, which costs much less than a display; on a laptop it is usually cheaper to replace the panel. Stuck OLED pixels: no. A small spot on a dark wallpaper is the thing most people choose to live with.
What to do
- Black, then white, then grey in full screen.
- Glows on black, gone on white: backlight — quote for a reflector repair versus a display.
- Present on white too: pixels — count and photograph.
- Stop the cause: no weight on the screen, a case with a raised lip, nothing in the same pocket.

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).
