Common use cases
Confirming native resolution scaling
Verify your monitor is running at true 1:1 pixel mapping rather than being upscaled or stretched.
Font and ClearType tuning
Check subpixel text rendering after changing scaling or ClearType/font-smoothing settings.
Frequently asked questions
- What should sharp text look like?
- Fine lines and small text should stay crisp with no color fringing; blur or fringing usually means the display is not at native resolution or scaling.
- Does this work on any monitor?
- Yes, though results are most meaningful when the display is set to its native resolution.
