Can you use an ipad as a second monitor screen ? (with a PC)

[chaparral]

Am sure i seen somewhere saying an iPad can be used as a second screen

But i don't know if this means with a windows PC or with just a Mac

I'm sure there are many pieces of software out there, this popped up near the top of a google search https://www.duetdisplay.com/

Thanks
