Frequently asked questions
- What is the difference between a dead and a stuck pixel?
- A dead pixel stays black in every color field; a stuck pixel shows a fixed color regardless of what the screen should display.
- How should I watch this?
- Play it full-screen in a dim room and look closely at each color field for any pixel that does not match the rest of the screen.
