Dead Pixels turns any screen into a convincingly defective panel: tiny black dead pixels and bright red, green, blue and white stuck pixels scattered across a solid test field, with an optional dead line, backlight-bleed glow and subtle flicker. Tap anywhere to plant more, or cycle the black/white/red/green/blue/grey test colours. Nothing is actually wrong — every defect is drawn on top of a normal web page.
What you can do with it
- Prank a friend — leave it fullscreen on their monitor or phone so they think the panel is failing
- A realistic "my new screen has dead pixels" reveal for videos, skits and reaction clips
- A quick solid-colour test field to eyeball a real display — turn the fake defects off first
How to use Dead Pixels
Open Customize to set the colours, title and behaviour, then press Fullscreen (or add ?present=1 to the URL) for a clean, controls-free screen. To run it unattended on a stream, copy the OBS browser-source URL; to drop it into a web page, use the <iframe> embed. Everything is a visual prop — no real hacking, network or data.
Is my screen actually damaged?
No. Every dead pixel, stuck pixel, line and bleed is drawn on a full-screen canvas over a normal page — your display is completely fine. Press Repair, or reload the page, and they all disappear instantly.
Can I use it as a real dead-pixel test?
Yes. Turn off the fake defects in Customize and cycle the solid black, white, red, green, blue and grey fields — any real dead or stuck pixels on your own screen show up against the flat colour.
How do I add or clear the defects?
Tap or click anywhere to plant a new pixel, use the action keys to scatter pixels or toggle the dead line, backlight bleed and flicker, and Repair clears everything at once.
