No Signal on my monitor.

[sigurthor_is]

Hello,
I'm trying to connect my GeForce GTX 570 to my monitor into D-Sub and the GPU doesnt have a VGA output.
So I bought a DVI to VGA Converter that i plugged into my monitor but the monitor says "No Signal Detectived".

What should I do ?

Look at your manual to see which DVI port supports an analog connection (DVI-I). You may have connected to a digital only DVI port (DVI-D). For more info, look here:
