Using an iMac 27" as an external monitor for a PC I have a Dell computer running Windows 10 and it have 3x DisplayPort and 1x vga outputs. I want to connect my iMac Core i5 27-Inch (Late 2013) as an external monitor to the dell pc. Can I buy a Mini DisplayPort -> DisplayPort (Male-Male) and connect the cable between the iMac and the PC and then use Target Mode to start seeing Windows on the iMac?

If that's not possible, is there any way to hook this up? I know of software solutions but I'm trying to do it physically unless I run out of options.
According to Apple KB : Use your iMac as a display with Target Display Mode you could use Mini Display Port cables for the 2009 &amp; 2010 models, but later models would appear to require Thunderbolt.
