PC won't detect a TV monitor connected with HDMI?

[TheSiphon]

Hello! So I lately had a bigger need for a second monitor as it would make things much easier for me. However, there is a problem. I connected my Samsung TV to my pc, but the PC won't detect the monitor? I have no clue what that happens. I tried to use a TV detection option on the Nvidia control panel, but it did not bring up a menu or anything. Any ideas why this happens?  The monitor is connected with a HDMI cable. I am not a good with these kind of things, any ideas?
