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 makes No Signal different
No Signal fills the screen with grainy analog TV static and a drifting “NO SIGNAL” box, or flips to the classic SMPTE colour-bars test card. It is the ambient, do-nothing filler of the set — a perfect between-scenes screen or a deadpan “the TV is broken” gag, with none of the terminal busywork.
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 it and it loops forever — grey analog static with a drifting “NO SIGNAL” box by default.
- Press number keys 1–3 (or the buttons) — INPUT flips between static and SMPTE colour bars, GLITCH tears and rolls the picture, CHANNEL nudges the status line.
- In Customize, set the AV input label and the status line, switch between static and colour-bars, and show or hide the drifting box and the OSD clock.
- Press Fullscreen (or add ?present=1) for a clean filler or a broken-TV prop.
Customize it
Switch between analog static and SMPTE colour bars, set the AV input label and the status line, and show or hide the drifting “NO SIGNAL” box and the on-screen clock.
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.
