Dual monitor setup issue - Both monitors detected but 2nd screen Is black

I recently upgraded my computer from using onboard graphics to a GTX 960 (GV-N960OC-4GD).

I previously had a dual monitor setup, with my primary monitor (SyncMaster2233sw) using a DVI cable and the secondary monitor (Syncmaster 173v) using a VGA cable. I purchased a DVI to VGA adapter to connect the secondary monitor, and while it detects the monitor the screen remains black as if it is in standby mode.

I can even move windows and my mouse onto the second monitor, however it obviously just disappears from sight. I've also tried switching the cables to see if it was a faulty port, however my primary monitor works in both, just the secondary that remains black.

Any help would be much appreciated!

GPU drivers:

UPDATE: The problem was just a faulty VGA-to-DVI adapter. That's what I get for buying it off eBay I guess.

UPDATE 2: It turns out that I needed a DVI-I adapter as my secondary screen apparently only accepts analogue output whereas I was using a DVI-D (digital) adapter.

Assuming that you are using a Windows machine, try the following:

1. See if the connections are correct.
2. Press Windows key + P.
3. Select duplicate or extend options.
4. Even now if the screen does not appear then check if you have powered on the 2nd monitor.

I fixed mine by turning off monitor, plugging the hdmi cable out of the laptop. Then turned off the main power switch for the monitor and waited for about 20 sec. Turned back on the power switch. Turned back on the monitor and insert the hdmi cable back into the laptop. Andddd it suddenly appeared on the other monitor too.
