Not every dead display looks broken in the obvious way. A panel that has failed electronically shows something stranger: bands of colour, frozen vertical lines, regions that have stopped updating. That is what this page draws , the failure mode rather than the impact.
What it simulates
LCD panel failure: colour banding, dead columns, and areas of the screen that have stopped responding. It is the look of a laptop with a damaged ribbon cable or a monitor with a failing driver board, rather than a phone that has been dropped.
How to run it
- Press Start fullscreen.
- Leave the device alone , this effect is at its most convincing when nothing is moving on top of it.
- Press Esc or tap Exit to end it.
Where it works
- Explaining what a hardware fault looks like to someone who has never seen one.
- A prop for a video or a photograph that needs a broken monitor without a broken monitor.
- A joke on a spare screen or an old laptop, where nobody is going to lose work over it.
- A quick comparison against a screen you actually suspect is failing , the difference between drawn banding and real banding is usually obvious side by side.
What it cannot do
It cannot damage a panel, alter a driver, or leave anything behind. It is a browser page and closing it ends the effect entirely.

Broken screen questions
Is my screen actually broken?
Not from this page. If you arrived here worried about a real fault, close the tab , if the problem persists, it is hardware. Use the black, white and grey test pages to look at it properly.
Why does this look different from the cracked screen page?
Because it is showing a different kind of failure. Cracked and broken glass screens show impact damage to the surface. This one shows what a panel does when its electronics fail , banding, frozen columns and dead regions, with the glass perfectly intact.
