lightroom vs Digital Photo Professional output resolution

Hi
Digital Photo Professional has 350 dpi output resolution

instead lightroom 240

dpp seems to have across the dpi , a better output result

which is the best for a good dpi output , 350 or 240?

Don't worry about it - until you come to resizing for printing it means nothing - all that matters are the number of pixels.

Most people use around 240-300 for printing, for display on screen it's absolutely meaningless
