How the No Signal screensaver works
The saver renders animated analog-style static noise across the full screen.
A bold "NO SIGNAL" message flickers in and out, with a fake resolution readout beneath it.
The static pattern is regenerated every frame for a genuinely noisy, un-repeating look.
No real display input is checked — it is a purely cosmetic effect.
A worked example
Left running, it looks exactly like a monitor that has lost its input source — flickering static and a bold warning, just like the real thing.
Settings & tips
- Accent recolours the warning text.
- The static is regenerated every frame, never repeating exactly.
- A nostalgic nod to CRT-era monitors.
