Penjelasan teknis
Each pattern is a solid CSS colour covering the viewport. A dead pixel stays black on every colour; a stuck pixel shows one colour permanently; a discoloured subpixel looks tinted. Because the page only draws colour, you are the detector — a browser cannot photograph the physical panel.
Full-screen mode hides browser chrome so it cannot hide a small defect near the edge. The browser compositor still renders the page, so this is not a hardware-level panel test. Very small or dim defects may only be visible on specific colours.
Pemecahan masalah
A spot looks black on every colour
Confirm it is not dust or a watermark by cleaning the screen and moving the window. A defect that stays in the same physical position is likely a dead pixel.
Full screen does not open
The Fullscreen API needs a user gesture and may be blocked in embedded browsers. Use the large colour buttons without full screen.
The whole screen looks tinted
Check night light, colour filters, HDR mode, and the monitor colour profile before assuming a panel fault.
A pixel changes colour with viewing angle
That is usually normal panel behaviour, not a dead pixel. Compare with a plain white field from directly in front.
