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
Q. What is the ROG Ally screen resolution?
1920×1080 pixels — 2,073,600 in total, about 2.1 megapixels, which puts it in the Full HD class.
Q. What is the pixel density of the ROG Ally?
315 ppi. That is the diagonal in pixels of a 1920×1080 grid divided by the 7" diagonal of the panel, and it makes each pixel about 80.7 micrometres across.
Q. How big is the ROG Ally screen in millimetres?
155 mm wide and 87.2 mm tall, worked out from the 7" diagonal and the 16:9 aspect ratio. The visible area is roughly 20.9 square inches.
Q. How far away do pixels stop being visible on the ROG Ally?
About 27.7 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.
Q. What aspect ratio does the ROG Ally use?
16:9, with the long edge 1.78× the short one. It is wider than it is tall, which suits video and side-by-side documents.
