Currently I have a old Lcd Tv (1360*720) as main screen for programming. I wanna replace it with something new, with a budget of < US 600. Programming and reading is my main activity. I do some gaming, and regularly movie watching. I wonder if at 4k is possible to have readable and *big* text not only for the content (code, websites... that is easy to configure), but also regular interface (menus, buttons, etc). People with experience with 4k/5k with low eyesight, is a true improvement or is a gimmick to buy 4k and is better to stick to regular tv/monitors?
