About Browser Resolution Values
Browsers commonly report screen dimensions in CSS pixels rather
than raw hardware pixels. On high-DPI or Retina displays, the
physical pixel resolution may be higher. The physical resolution
shown here is an estimate based on screen size multiplied by
Device Pixel Ratio and may not match every device exactly.
