iMac 21’5 late 2015 as a monitor for my pc

So i’ve been wondering if my pc with an apu could be connected to my iMac with a Hdmi to mini display port. I’m using a Ryzen 5 2400g and Asus prime b450m-a.

Unfortunately will not work for the late 2014 and newer machines. This is a fairly well documented issue on just about every Windows or Mac related forum.

But technically the Thunderbolt 2 connector's the same as a mini display port right? "Thunderbolt is fully compatible with Mini DisplayPort peripherals . Technically, the plug is the same and the only difference is that the Thunderboltconnector can carry – in addition to the classic Mini DisplayPort – a Thunderbolt signal, which is a signal PCI-Express (4 lines)."

You would need to enter target display mode which is simply not supported on machines after late 2014. Additionally target display mode was very picky and did not support hdmi to mini display port or thunderbolt.
