What is LCP by screen resolution
LCP by screen resolution shows the Largest Contentful Paint (LCP) value across different screen resolutions (e.g. 1920x1080, 1440x900). This lens helps you identify which screen resolutions deliver a slower experience for your users.
The list shows only screen resolutions that generated traffic to your website during the selected period.
Common reason for slower LCP on certain screen resolutions is differences in hardware. Less capable hardware can affect LCP timing.
LCP is the most popular vital from the Core Web Vitals and represents the loading time of the largest element on the page.
Healthy LCP by screen resolution sample
Should you worry
A healthy LCP by screen resolution lens looks all green. Some screen resolutions may be greener than others, but as long as there's no yellow or red, it’s considered healthy. The greener the screen resolution, the better.
Unhealthy LCP by screen resolution sample
In the example below, LCP by screen resolutions shows that devices with a resolution of 1920x1080 and 1366x768 are both most popular and producing bad LCP. This often leads to a higher bounce rate, more exits, and lower conversion rates.
Resolving unhealthy LCP by screen resolution
Go-to action plan to resolve an unhealthy LCP by screen resolution:
Ask Uxi to analyze your LCP by screen resolution values and suggest improvements.
Use Filters to focus on the slow screen resolutions in your LCP by screen resolution then look across the other LCP lenses to find which ones show the slowest LCPs with the most pageviews.
Simulate LCP of the suspected lens to see if fixing it will resolve the slow LCP by screen resolution. If yes, this is where the resolution focus should be.
Use an automated LCP optimization tool like Navigation AI to improve your LCP by screen resolution values.
Once you’ve improved LCP, set an alert to be the first to know if it starts worsening again.
