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 34" ultrawide QHD screen resolution?
3440×1440 pixels — 4,953,600 in total, about 5 megapixels, which puts it in the QHD+ class.
QWhat is the pixel density of the 34" ultrawide QHD?
110 ppi. That is the diagonal in pixels of a 3440×1440 grid divided by the 34" diagonal of the panel, and it makes each pixel about 231.6 micrometres across.
QHow big is the 34" ultrawide QHD screen in millimetres?
796.6 mm wide and 333.5 mm tall, worked out from the 34" diagonal and the 43:18 aspect ratio. The visible area is roughly 411.8 square inches.
QHow far away do pixels stop being visible on the 34" ultrawide QHD?
About 79.6 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 34" ultrawide QHD use?
21:9 (exactly 43:18), with the long edge 2.39× the short one. It is wider than it is tall, which suits video and side-by-side documents.
