How do you know your cards video output is actually switching? I mean, if you have your video monitor cable plugged into the VGA port on the video card does the display just go out?

I have seen an issue like this before where the display starts to cycling through input modes
VGA > DVI > HDMI randomly on bootup. This can happen on TV'S as well where it will cycle through input modes.
Possible Culprits
- Bad VGA > DVI > HDMI cable whatever cable you're using is bad
- Bad VGA > DVI > HDMI port on the PC or Laptop
- Bad VGA > DVI > HDMI Port on the Graphics Card try another port
- Bad VGA > DVI > HDMI Adaptor or Convertor
- Bent Pins on cable or port
- Bad VGA > DVI > HDMI port on the Monitor
- Bad Driver install, clean out old driver and reinstall
Also, check for settings in BIOS and on the Monitor or TV.
Hope this helps you out.
