Third monitor not working, showing up in Resolution & Display settings.

[iamkitten]

I have three monitors which i'm trying to get to work together.

System specs:
CPU: Intel Core i5-2320
GPU: NVIDIA GeForce GTX 770
RAM: 16GB
PSU: 750W EVEA (gold)
Windows 10 64bit

I've got each monitor connected though different cables. One HDMI, one VGA and one DVI which are all connected to my 770 graphics card. The ones connected though VGA and DVI are both working fine but the HDMI one isn't. It is showing up in my screen resolution and display settings where i can move it around and change resolution but nothing happens, my third monitor just displays the message "No signal though PC"

If i unplug my HDMI cable it does not how up again in screen resolution and display settings unless i restart my pc.

Thankful for any help i can get.

On your hdmi monitor, is there a source selection option?
Not all monitors autodetect the cable.
