Windows 7: Dual Monitors, Monitor two black

Dual Monitors, Monitor two black

Hi guys ok so I have two screens set up one of them is my usual display.
A acer x223HQ PC monitor the other is a Samsung TV

There are both connected into the graphics card and not the motherboard. but yet screen two is black.

The rez for both screens are set too 1440x900 the monitor can go to 1920 but as the TV can not I lower them both to what the TV can.

The one thing that is bugging me is that the TV refresh rate is set to 75hz while the monitor is set to 60, when ever I try and lower the TV hz too 60 to match the monitor is flicks then sets itself back to 75hz. (doing this in nvidia;s control panel.

I will fill out my full specs in a few min, then i will go get my laptop to see if it is the TV that is messing with the rig

I have just noticed that the 2nd monitor has now changed from its amber light to a blue one. but is still black.

Thanks for any help!
