As I understand, from reading and my own experiments in making audio visuals, it makes absolutely no difference to a video screen what the ppi is set at. A crop 1024 x 768 at 10 ppi looks identical with one at 100 ppi. Why is therefore that Save for web and devices in Photoshop always produces an image that has its document size reolution shown as 72 ppi which is the figure that used to be erroneously quoted as being best for images to be displayed on monitors? Does this help to perpetuate the wrong message?
Many thanks
