4K compatibility started as far back as Build 810 (if not earlier), but 940 was the Official version to be fully 4K optimised.

Build 950 or 960 was the first to expose the TerminalInfoInteger(TERMINAL_SCREEN_DPI) API

Are you living in a cavern ? Usually when talking with people, and certainly if you are the one who is asking for answers, you are trying to be polite and respectful.
