Test your monitor and display for dead/stuck pixels, UFO ghosting motion blur, measured refresh rate (Hz), and color banding in full screen.
Unpowered subpixels that remain completely dark/black across lighter color backgrounds.
Subpixels with transistors stuck open; shines red, green, or blue. Can often be revived via the Stuck Pixel Fixer.
All subpixels permanently powered at maximum capacity; glows bright white even on a pure black background.
In the Dead Pixel tab, click 'Launch Fullscreen Test'.
Inspect solid black, white, red, green, and blue screens for dark unpowered spots or miscolored pixels.
In the UFO Ghosting tab, follow moving lines to evaluate panel response time and real-time Hz.
If you spot a stuck single-color pixel, place the noise box from Stuck Pixel Fixer over it.
A dead pixel is completely unpowered (usually black) and cannot be fixed. A stuck pixel is locked on one subpixel color (red, green, or blue) and can often be massaged back into operation.
Ghosting occurs when pixel transition times lag behind the display refresh rate, leaving trails behind moving objects. Fast response panels (1ms) and higher refresh rates minimize this artifact.
