I am having GeForce GTX 570 in my system and I am having three monitor connected to the system and the problem that I am facing is that the Third monitor is not working, I have tried updating the driver but then it is not making any difference, it was working well previously and if found the Third monitor to be off suddenly, is there anyone who can help me out??

Before I suggest you something about the same I just wanted to know had you changed the BIOS settings and so?? And as you said that it was working well before so have you tried rolling back or installing the same driver?? Other than this just make sure that the cables are secure, just check these things out and let me know if it is helping or not. Let me know the solutions that you have tried so far so that I don’t suggest you the same.

By now I had tried installing the latest driver but then it did not helped and as far as the connection is concerned it is secured, I have not made any changes in the bios, after your suggestion I have tried rolling back to the previous driver but I don’t know why it is not helping. I have checked out the rigorous display detection in the control panel but then did not had any luck yet, is there any other solution that I can try out to fix this out??

There are possibilities that the port that you might be connecting to the third monitor might have gone faulty, so just try to check that out by connecting the other monitors to that port and see if it is working or not. If that’s not working then try out performing 5 minute cold power-down and unplugging the psu for that moment.

I have tried checking the port but then it is working for the other monitors, other than this I have tried out disconnecting outlet power cables and the monitors as well and even unplugging the psu and then plugging them again but then no matter what I try I am not able to get the Third monitor working, is there any other option that I can try out now?? Any further help for the same will be highly appreciated.
