How to read this
- Pixel density (ppi) is how many pixels fit in one inch. Resolution alone cannot tell you — you have to divide by the diagonal.
- The same 4K is 163 ppi on a 27" monitor and 68 ppi on a 65" TV. That is more than double, but a TV is watched from far away, so it does not matter.
- The distance at which pixels vanish comes from one arcminute, the limit of human sight. Once a pixel looks smaller than that, no eye can find the grid.
- Aspect ratio is width and height reduced to the simplest whole numbers. Modern phones are 19.5:9 or 20:9, so 16:9 video leaves black bars on the sides.
Frequently asked questions
QWhat is the Surface Pro 9 screen resolution?
1920×2880 pixels — 5,529,600 in total, about 5.5 megapixels, which puts it in the 2.8K class.
QWhat is the pixel density of the Surface Pro 9?
266 ppi. That is the diagonal in pixels of a 1920×2880 grid divided by the 13" diagonal of the panel, and it makes each pixel about 95.4 micrometres across.
QHow big is the Surface Pro 9 screen in millimetres?
183.2 mm wide and 274.7 mm tall, worked out from the 13" diagonal and the 2:3 aspect ratio. The visible area is roughly 78 square inches.
QHow far away do pixels stop being visible on the Surface Pro 9?
About 32.8 cm. That is where a pixel subtends less than one arcminute, the limit of human sight — closer than that and the grid starts to show.
QWhat aspect ratio does the Surface Pro 9 use?
3:2 (exactly 2:3), with the long edge 1.5× the short one. It is taller than it is wide, which suits a device you hold in one hand.
