Should I upgrade to 4k? Or does my set up need work?

Increasing resolution will only make the text smaller, I sit 7 feet from my 65 inch. 4K tv, but I've never had a problem with text size.Maybe you should try this link https://goo.gl/sN4UYb since CivBE's fonts are known for being unreadable for some people.Hope that helps :)
