Yesterday I had an issue after using my tv on the dp port on my gtx780 ti to set the bios on my board.  My hdmi port went weird which is why I went to dp and then immediately after setting the bios and rebooting everything turned green.  I thought that perhaps my card had gone bad so I swapped it out with an evga gtx760 and it did the exact same thing.  I pulled it, reset the bios and went to the integrated graphics which worked right while I was trouble shooting this build and it went away.  I was wondering what caused this to happen because my screen stayed green all the way into windows.
 

The tv was 0on the gtx780 ti dp feed and when this happened I didn't have any hdmi output to my monitor which is why I turned on my tv.  After I reset the bios and reinstalled my gtx780 ti everything went back to normal.  I never tried using the dp port on the integrated graphics only the hdmi to the monitor.  I was just concerned about the green hue overriding everything else because I remembered seeing something like that on the xbox called the green screen of death.  Hey I appreciate you trying to help me out with these issues.
