Thunderbolt > HDMI fails "No signal"

I just bought an after market cable with a HDMI in one end and a Thunderbolt in the other to connect my iMac (late 2013) to my Samsung TV. But when i connect the two it just says "no signal" on the TV. I have tried both Thunderbolt-ports on my iMac and all HDMI-ports on my TV with the same result. Also i don't get the "arrangements" option in my displays settings tab.

When i have the two devices connected and then turn on the TV the screen on my iMac starts flashing, as if it is trying to connect but fails, but no error message shows up. After a little bit of trying i touched the HDMI end in the TV and noticed that it was VERY hot so i immediately unplugged it. What is wrong here?

"it was VERY hot"

Not good, seems like maybe you've got a faulty or incompatible cable. You should send that cable back or cut it up, so that it can never be accidentally plugged it into your iMac.

Try getting and using a "Mini DisplayPort to HDM adapter" and an HDMI cable.

(not the cheap one, get a Moshi, Belkin, StarTech, Monoprice adapter)

Sorry. I posted the link so you could see if you had the correct cable. As den.thed said, you need a mini DisplayPort to HDMI cable.

Thanks. I have the correct cable. But most likely it's broken in some way, i called the store today. I will buy an adapter instead of this cable that i now have.

Thanks. Yes it seems very much like it's the caple that is broken. It was really hot when i unplugged it. I called the store today and they said i'm free to return it. If i don't get this to work before i return it i will buy an adapter instead.
