| Hynad said: What I wish to get is 300dpi on a 32". I use a 1080p 32" as a PC monitor, on which I draw on Painter and Photoshop. So the added pixel density would be Godsent to me. OP: 43.2 at roughly 3 feets away from a 32"... I think your formulae is erroneous. |
That sounds about right
32" 1920x1080, that's 1920 pixels over a width of 32 * (16 / sqrroot ((16^2) + (9^2))) = 27.89" wide
From 3 feet away 1 degree covers (3*12) * tan(1) = 0.628"
1920 * (0.628 / 27.89) = 43.2 pixels in 1 degree looking dead on at the screen.
300dpi on a 32" that's over 8K or (300*27.89) 8367 pixels horizontally. That would give you 188 pixels per degree in the center. Close to the limit at human vision of 200 pixels. That would be ideal for drawing on a 32" monitor from 3ft away. It should be possible since they can already make 440dpi 1080p panels.
