| NATO said: You're wrong. the image is 755x425 for everyone regardless of device since it's a forum post, and if the user manually opens the image, it will depend how their browser handles it, if it displays the image at it's full resolution and the end users display is sub-4k, then it will only display a portion of the image, if the browser resizes to fit then the image will be whatever resolution it was resized to, using the scaling method relative to the browser. You should read the post again, and of course you have to open the picture to see th actual image size. And thats going to be depenent on a number of factors even if you are seeing the actual resolution. Strange way to have a constructive conversation...... everything you mentioned are factors..... they however do not negate everything I have said as such a statement may suggest.
They are "designed" to be viewed from further distances? Where is that written on any larger display box ever? "designed to be viewed from X and X distance". Also the 720ppi at 4 inch thing isn't accurate because the human eye does not see in grids, additionally the format of the display effect the perceived complexity of the final image, standard grid layout versus hex layout, dot array and so on, the receptors in the eye are densly packed but randomly packed, thus 720ppi seen by the eye isnt the same as 720ppi on a display, the clarity of angles and resolve of edge details is much greater in reality than what a grid display can emulate, so even if the 720ppi matches the average maximum of a human eye, it's still much lower perceived resolution than the real world. Talk like this kinda makes me realize that everything you are doing here is just an attempt to dismiss everything i have said. Yes the human eye doesn't see in grids. But thats the whole point, the human eye CANNOT see higher than 876PPI (display) equivalent from a distance higher than 4 inches. and get this....... Last but not least theres the issue of focus, the human eye can focus on things at different depths to resolve further information, for example if you take a picture of a room then try to read the title of a book from that image, you'll likely struggle, but being sat in the same room and looking at the book it would be a hell of a lot clearer, even though the human eye can only perceive at a fixed ppi, it can resolve greater detail from the area around it because of that ability to change focal depth, in effect, adjusting the PPI of a specific focal point at the cost of PPI of the now unfocused area. Its because of our inability to focus on things that are closer than 4" from our face. If you really wantthe details... here goes: The the perfect resolution of the eye can see 2190 PPI at 4 inches from the screen. However, none of us holds our phones that close to our faces, at least I hope you don’t, because that actually is bad for your eyes. In addition, the average visual acuity of a human is about 1 arc minute, which simply refers to a person with 20/20 vision. A person with 20/20 vision at 4 inches (the closest a healthy adult can focus) can see up to 876 PPI, which is considerably lower than the ideal eye, which can see at .4 arc minutes. A display, even at the same "maximum" of the human eye cannot adjust to resolve detail in particular areas of an image, it can only display a fixed image with a fixed PPI. |
Answers in bold... I do not expect to have convinced you..... but I do at least hope that you still don't think everything I said was nonsense and maybe that next time you would consider sharing your own opinions in a way that doesn't come off as being dismissive. You don't have to dismiss mine to make yours so to speak. Thanks.

Read replies to the above poster too I guess.
