Overview

That annoying dot on your screen? Test it, identify it, and try to fix it.

What a stuck or dead pixel actually is

This is a different kind of problem from a screen that flickers, dims, or looks generally blurry — those affect the whole display at once, while a stuck or dead pixel is one exact spot on the panel behaving differently from every pixel around it. Your screen is built from millions of tiny individual dots; a “stuck” pixel is frozen showing a single color — often red, green, or blue — instead of changing with the picture, while a “dead” pixel shows no light at all, a tiny black dot.

It's a physical characteristic of that one point on the panel itself, not a setting, a scaling mismatch, or a color-profile issue — it stays in the exact same spot no matter what's on screen or which app you're using.

How to tell a pixel problem from other display issues

How serious is it?

Usually minor

A single stuck or dead pixel is almost always purely cosmetic — it doesn't affect how the rest of the screen or the PC works.

Worth taking seriously

Manufacturers typically only cover dead or stuck pixels under warranty once a certain number appear, or if several are clustered close together, and only within a limited time window — it's worth checking your specific manufacturer's policy and warranty period before it lapses, rather than assuming either that it's automatically covered or automatically not.

Why a lot of the advice floating around is a risky guess

Plenty of the DIY tricks people pass around for this don't work for every kind of pixel fault — a stuck pixel and a truly dead one aren't the same underlying issue — and some of the physical ones carry a real risk of making things worse or running into warranty terms about screen damage.

WindowsHelper is being built to help you work out how many pixels are affected, where they sit, and how that compares with what your specific manufacturer's warranty covers — instead of leaving you to guess whether it's worth pursuing a repair or a replacement.

Common questions

What's the difference between a stuck pixel and a dead pixel?
A stuck pixel is frozen showing a color — often red, green, or blue — while a dead pixel shows no light at all, appearing as a tiny black dot. They can look similar at a glance but aren't the same underlying issue.
Will a stuck or dead pixel spread or get worse?
Usually it stays as it is, though it's worth keeping an eye on whether the count or pattern changes over time rather than assuming it's fixed in place.
Is this covered under warranty?
It depends on your manufacturer's specific policy — most set a minimum number of pixels, or a clustering rule, before they'll act, and only within a limited window, so it's worth checking your terms directly rather than assuming either way.
Could this be a cable or connection issue instead of the panel itself?
It's worth ruling out — a spot that flickers, shifts position, or comes and goes points more toward the connection or signal, whereas a fixed, unchanging dot in the same place points more toward the panel itself.
Is it safe to just live with it?
Generally yes — it's cosmetic and doesn't affect the PC underneath. The main reason not to ignore it indefinitely is that a warranty claim window can close while you wait.
