Please see the very restrictive hardware and OS requirement for Apple's now-dead Target Display Mode (TDM):
Use your iMac as a display with target display mode - Apple Support
Although the 2011 iMac was among the few iMacs that could do TDM, the last Minis that could use it as a display are now almost four years old.
