screen resolution is afaik always 72dpi - and even if not it would 
depend on the output device that you can't control. All images for the 
web are generated with 72dpi.

But before changing things based on my personal taste I'd wait for 
others to give feedback.

not out of the box. But a quick research showed it should be "-set 
density 300", where 300 are the dpi to use. So the complete imageMagick 
command should be:
convert image.jpg  -set density 300  output.jpg
