Dead Pixel Test
Photosensitivity Warning
Continuous mode rapidly flashes bright colors, which may trigger seizures in people with photosensitive epilepsy. Stop immediately if you feel dizzy, disoriented, or unwell.
Enabling Per Pixel mode may help somewhat, since the screen shows noise instead of one solid flashing color, but it does not remove the risk.
