FAQ
- How is PPI calculated?
- The pixel diagonal, from the width and height, divided by the physical diagonal in inches.
- Does this use the size on the box?
- Use the panel’s actual diagonal, not the size of the stand or the outer frame.
- How is this different from the screen PPI tool?
- This one uses the pixel counts you type. The screen PPI tool multiplies CSS pixels by this device’s pixel ratio.
