IMAC as a 2nd screen
Can I link my IMAC as a 2nd screen to a windows laptop ? my IMAC is end 2012.
Question marked as
Doubtful if the few limited target display modes would work,
to attach iMac (2012) to Windows-based portable computers.
However there may be some clues in this Apple Support article:
• Use your iMac as a display - Apple Support

(Depending which macOS runs your Mac: note three latest are referenced within this article.)
More info suggests this only may work between supported Apple computers:
