Why Test on Xiaomi POCO X7?
Viewport

Pixel Density (DPR)
High pixel density exposes image quality, scaling inconsistencies and minor visual flaws.
Performance & Animations
Solid mid-range chip — UI stutters and slow load times are visible without excessive hardware headroom masking them.
Viewport Size (CSS Resolution)
The CSS viewport defines how media queries, layout breakpoints, and responsive components behave.
For Xiaomi POCO X7, the CSS viewport measures:
