They all in theory have exactly the same sharpness. Variations are due to blurring and diffraction effects of the layers on top of the actual active part of the scree,
PC graphics modes are often confusingly stated as HD resolution, or SVGA resolution or 4K resolution. These are not resolutions as you need to know the screen size. It's horizontal (or vertical) physical dots or pixel count divided by screen width in inches that gives the dpi or ppi.
Vertical will give the same answer unless the dots/pixels are not the same size in both axis. Thus a 15″ a true HD format monitor/screen has identical resolution to a 30″ 4K (PC/TV not Cinema) monitor screen, if both are 16:9 aspect ration (about 147 ppi). True "HD" at 16:9 is 1920 x 1089 vs 3840 x 2160 for "4K" 16:9 monitor/TV irrespective of screen size.
See https://www.sven.de/dpi/
Thus for about 300 dpi an HD screen would be about 7.4" diagonal and for 4K about 14.8" (14.685" is very close to 300 dpi).
Screen size or total number of pixels alone tells you nothing about resolution. Resolution is number of pixels on a line divided by the phyiscal length of the line. |
Sorry for misstating the PW4 resolution. I was remembering the older PW! and PW2 units which did have lower resolution.
