Every display looks better if you have a less-than-perfect eyesight. Without glasses and from where I am sitting, I can't tell whether my TV is or not HD, therefore, it looks every bit as good as a 2160p device would look from the same distance. In fact, if the podcast I am watching right now were in HD, it would look exactly the way it looks right now.
I would be as unable to read small print in the slides as if I were there on the front row.
