DP/HDMI not working togeather

[toastdude123]

Just resonantly I have not been able to use duel monitors, I use displayport for my main and HDMI for my secondary, when both are plugin in at the same time only the HDMI monitor will work, when I unplug that monitor the displayport monitor will work.

 

It is not a windows 8.1 setting, I checked all of that. 

 

When both are plunged in in my NVIDIA control panel I get this...

It should support 4 monitors at the same time.

Does it work when the HDMI cable isn't plugged in?

Do you run the latest driver?

I have the latest drivers, I just checked, When I don't have the HDMI cable plugged in, the DP monitor works just fine; a few weeks ago I could run both 100% fine (over 8 months of it being stable)

Did the issue apear after installing new drivers?

You can try to install a old once for testing.

 

Don't think your GPU is to blame since both interfaces work. It is for 99% a software issue.

Does the monitors have some more inputs so you can switch?
