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 Steam Deck OLED screen resolution?
1280×800 pixels — 1,024,000 in total, about 1 megapixels, which puts it in the HD class.
Q. What is the pixel density of the Steam Deck OLED?
204 ppi. That is the diagonal in pixels of a 1280×800 grid divided by the 7.4" diagonal of the panel, and it makes each pixel about 124.5 micrometres across.
Q. How big is the Steam Deck OLED screen in millimetres?
159.4 mm wide and 99.6 mm tall, worked out from the 7.4" diagonal and the 8:5 aspect ratio. The visible area is roughly 24.6 square inches.
Q. How far away do pixels stop being visible on the Steam Deck OLED?
About 42.8 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.
Q. What aspect ratio does the Steam Deck OLED use?
16:10 (exactly 8:5), with the long edge 1.6× the short one. It is wider than it is tall, which suits video and side-by-side documents.
