I don&#x27;t think they would for me.<p>My Dell u2412m has a pixel density of 94 PPI (I think?) which is quite low for today&#x27;s standards but it does the job and I can&#x27;t justify upgrading it. Compare this to my current smartphone (xperia z3 compact) which at 720p has 319 PPI and is still considered low end in this regard.<p>Work provided me with a macbook pro retina and I don&#x27;t see what&#x27;s the fuss about. Hence running mostly on clam-shell mode.<p>On older notebooks I simply use the Dina font which looks great on low res screns.<p>Of course when I go to the stores and see these 4k TVs I definitely notice a difference but we&#x27;re not talking media consumption here.<p>I feel the same about 21:9 aspect ratios or multi monitor setups. My favorites are still 4:3 or 16:10. I used to have a multi monitor setup for a while but ended up selling it.<p>I might have to get my eyes looked at, or maybe I spent too much time staring at mainframe screens.
