No Signal fills the screen with grainy analog television static and a floating “NO SIGNAL” box that drifts around the edges, exactly like an old TV on a dead input. Flip to colour-bars mode for the classic SMPTE test card. It loops forever and asks nothing of you — a perfect ambient filler or a deadpan “something’s wrong with the TV” gag.
What you can do with it
- A deadpan “the TV is broken” prank on a monitor or television
- An ambient retro filler between scenes for streams and videos
- A believable dead-input or test-card prop for film and photography
How to use No Signal
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 anything actually wrong with the screen?
No. The static and test bars are a full-screen animation — there is no broken input and nothing to fix. Press Escape or reload to leave.
Can I switch between static and colour bars?
Yes. Use the on-screen toggle (or the mode action) to flip between analog static and the SMPTE colour-bars test card at any time.
