Frequently Asked Questions

How do I compare two custom display sizes?

Select '— Custom —' in either Device A or Device B dropdown above, then enter the native pixel width, pixel height, and screen diagonal in inches.

What does the PPI difference percentage mean?

The percentage difference shows how much denser the winning display is relative to the lower-density display: ((Higher PPI - Lower PPI) / Lower PPI) × 100%.

Does higher PPI automatically mean a better screen?

Not necessarily. While higher PPI makes text and curves sharper, color accuracy, contrast ratio (e.g. OLED vs LCD), peak brightness, and viewing distance also determine visual quality.
