I bought a lead on eBay for a fiver, it was one of these..

But it doesn't fit into my PC.

I have the 15 pin blue lead monitor type in the back of my monitor, will I need to buy one of these to a hdmi connector lead? All the videos on YouTube don't have my PC type of leads?

Is this all I need to run my Windows 10 PC tower through my tv to play mame?

I won't need to buy any other converter or wires will I? Why does that eBay link at the end say something about a converter?
