iMac as a Monitor?

[captain_cereal_hands]

I wasn't sure where to put this question. I have an iMac from late 2013 and I need to know if I can use it only as a monitor for my PC. My monitor is on its way out and if it dies on the sudden this is the only other thing I have that I could use.

 

This is the GPU I have https://pcpartpicker.com/product/bNcMnQ/evga-video-card-08gp46286

 

Any help is appreciated.

i believe you can only use a thunderbolt-equipped Mac as a source to do that on that model iMac...

That models not supported, but the ones that are can use any DP source
