Second Monitor Displays Nothing

[Bob1234567890]

I have a NvidiaGT 620. I am using windows 7 64 bit ultimate.

I want to reset up my PC with dual monitors which has worked in the past.

The Nvida control panel sees both monitors and allows me to configure them as anextended view. The primary monitor works, the second one shows nothing.

I am not sure how to solve this, any help would be greatly appreciated.

Any advice on how to get this working again would be great.

I have tested that the second monitor works by connecting it to another computer.

I have replaced the video card with an EVGA GT730 and stillhave the same problem. No second monitoreven though both monitors show up correctly in Windows “Change Resolution” and NvidiaControl Panel “Displays”. When I turnthe power off on the second monitor I see the windows flag for ½ a second andthen it goes blank.



Any ideas how to fix this?
