DVD's are 480p. The numbers are short hand for the number of pixels on the screen. The higher the number, normally the better clarity of picture.
Does the quality of DVD go up if you play it on a Blu Ray? Exactly what is the best way to watch DS9 that is available? I recently watched it on Amazon Prime. It looks okay but not nearly as good as TNG,TOS and Enterprise.

I should also ask if the kind of tv matters. I got a 50" Class LED and the brand name is element. I think that is the brand name. Not sure why else that word would be written on the box it came in on.
