Am not sure that's a great idea. A typical 4k monitor simply crams more pixels into the same space as a normal one. While it may be able to display the equivalent of four regular windows at once, the text and UI will be so small it could be difficult to use.
Generally when using a 4k monitor the OS is set to scale everything back up to a more normal size which means you don't gain anything in terms of screen space. I reckon multiple monitors makes more sense if you've got space for them.
