A white spot on a laptop 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.

Test it now

Full-screen black: the spot glows. Full-screen white: it disappears (backlight) or stays as a lighter patch (stuck pixels, OLED). Grey shows how big the affected area really is.

What it is

A white spot on a laptop 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

  1. Black, then white, then grey in full screen.
  2. Glows on black, gone on white: backlight — quote for a reflector repair versus a display.
  3. Present on white too: pixels — count and photograph.
  4. Stop the cause: no weight on the screen, a case with a raised lip, nothing in the same pocket.

What a repair costs

United States$100–300 for a new panel (parts $50–150 plus labour); budget and 1080p panels at the low end, touch and high-refresh panels at the high end
India₹3,000–8,000 for a new panel at an independent repair shop; ₹6,000–15,000 at the brand service centre

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).
