Step through red, green, blue, white and black in full screen. Black square on every colour: dead. Same coloured square on every colour: stuck. White square on black: hot.
What it is
A dead pixel on a laptop screen is a single tiny square that stays black on every colour. A stuck pixel is a square that stays one colour — red, green or blue — on every colour. A hot pixel is one that stays white. They are single sub-pixel transistors that have failed; they do not spread.
Can it be fixed?
Stuck: often — run the pixel fixer on the test page over it for 10–20 minutes; it flashes colours fast to unstick the transistor. Dead and hot: no. Whether the maker replaces the panel depends on how many there are: see the dead pixel policy by brand.
What to do
- Full-screen test, all five colours, count the squares.
- Coloured square: pixel fixer, 10–20 minutes, twice.
- Black or white square: photograph on the colour that shows it best.
- Check the count against your brand's policy and claim if it qualifies.

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).
