Nope it doesn't work. This has been discussed before several times. Since iMacs got thunderbolt (late 2012 model), using the iMac as an external PC display is not possible. This is an unnecessary limitation afaik, so you could always send Apple a complaint...
 
This is bad news
There is no ways we can use imac late 2013 as monitor display for pc?
