Hi Heinz-
You are way more experienced than I am, and I have seen what you say written elsewhere..... however, I only know what I experienced on my 54" TV. At the low "print" resolution of 72-180 dpi, all the stills in the photo show, they showed very pixelly and had moire onscreen. When I resized all to a 300 dpi, same pixel size, they were much crisper, as crisp as they could be on a sdtv.

Hmmmm.....

Vicki,

As Heinz stated, DPI is applicable to print media only. Pixels are the unit of measure for digital display, ie monitors and TV.

Pixels Per Inch or PPI refers to how closely pixels are packed together in an inch of space. It doesn't matter whether you're talking about a screen or a printer.

Dots Per Inch or DPI refers to how many dots a printer uses to create a single pixel when it's printing one of your photos. If you sent a 240 ppi image to a 720 dpi printer each pixel will be represented by 3 tiny dots on the paper. A 2880 dpi printer will use 12 tiny dots of ink to represent each pixel.

This may explain it better: DPI vs PPI
