Why do people say a smaller tv/monitor is better for playing Apex?

Gamers who use monitors/small TVs sit at less than arm's reach from the screen.  Going from playing on a home TV to playing on a high quality 27" monitor changed my game completely.  I'm an older player like yourself, and wear my strong reading glasses when playing.  I can see SO much more than when I was on a TV.  I would literally never go back to playing that way, I'd rather not play.
