When i try to set up both my monitors it only works when i do duplicate and when i switch to extend my second monitor goes black
 


it is still black nothing ever shows up but when i hit identify the number shows up
 
i have used a tv as a second monitor over vga, and nothing would show up until i turned the resolution down because the computer couldn't detect the maximum resolution that the tv could handle for some reason. but if the number shows up, its getting a signal.
 


like you can tell the monitor is staying on its just that nothing is showing up
 
Are you using AMD or Nvidia? either one you need to enable the monitor and do some minor configuration using Windows and or your GPU driver These settings are found in Display and Resolution or Change position resolution.
