I'm getting more and more confused with all this. For me, a pixel is a pixel, and the DPI are related to the "device" that is going to show/print" it. If someone needs more details, depending on the "final device", then increase the number of pixels of the rendered picture.

you can't Increase the DPI expecting it to be of better quality keeping the actual dimensions of the Image. The Image Dimension will shrink into a tumb nail in a extreme case to keep the quality but the print quality will not get better on your A4 it will just not fill out the paper, or digitally fill your screen without having to Zoom in the high res Render, having again a quality loss.
