I have a few old PAL VCDs that I am toying with and of course they don't look all that good on my 1280x1024 monitor. However, I copied the mpeg .DAT file (no conversion) and transferred it on a Samsung Galaxy Core Plus smartphone where I played it with VLC and I noticed it's a little bit sharper on its native resolution of 352x288. Was it because my eyes were closer to the screen? Can this actually "improve" the viewing quality or it is just my imagination? I'm asking more generally here. Can a high PPI display impove a low resolution video or will it only look tinier? Well, is there anyone who can reply or direct me to an appropriate source of information?
