random display changes dvi to vga

[basher2342000]

i recently running a GeForce 550ti gpu ran great, good fps in games  once in awhile the display will shutdown and switch it self from dvi to vga input, even running a direct dvi cable from pc to monitor i changed to a different gpu and not having problems after that, anyone in chat knows why it does that. your answers will help greatly a question of a problem nobody maybe not heard about.

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?

So your 550ti has 2 dvi ports and one mini hdmi. Where are you getting vga output from?

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.
