What is INP by screen resolution

INP by screen resolution shows the Interaction to Next Paint (INP) value across different screen resolutions (e.g. 1920×1080, 1366×768). This lens helps you pinpoint which screen resolutions result in slower responsiveness for your users.

Only screen resolutions that had real traffic during the selected period are shown.

Differences in hardware are a common reason for degraded INP on certain resolutions — some resolutions are more common on lower-end or older devices that may struggle with input responsiveness. INP is one of the Core Web Vitals and measures how fast a page responds to user interactions.

Should you worry

If your INP by screen resolution lens is all green, you’re in good shape. Some resolutions may be slightly better or worse, but as long as there’s no yellow or red, user interaction performance is likely strong across devices.

Unhealthy INP by screen resolution sample

If INP is poor for common screen resolutions like 1920×1080 or 1366×768, that’s a problem. These are extremely popular screen sizes, and slow responsiveness here can:

  • Increase bounce rate

  • Create frustration on interactive pages

  • Lower your conversion rate

Resolving unhealthy INP by screen resolution

Go-to action plan to resolve an unhealthy INP by screen resolution:

  1. Ask Uxi to analyze your INP by screen resolution values and suggest improvements.

  2. Use Filters to isolate slow screen resolutions, then explore other INP lenses

  3. Simulate INP of the suspected lens to see if fixing it will resolve the INP by screen resolution. If yes, this is where the resolution focus should be.

  4. Use an automated INP optimization tool like INProve to improve your INP by screen resolution values.

  5. Once you’ve improved INP, set an alert to be the first to know if it starts worsening again.
