A while back I purchased an Asus 27" monitor(Model number VZ279H) and when I went to use it, it would just give a black screen, at first I assumed it was a problem with the graphics card, so I plugged the monitor into the onboard graphics... Same outcome. I then tried plugging the monitor into my other pc yet again the same outcome. Just to make sure it wasn't the computers for sure I used my old monitor which I know for a fact works and the success of that led my concern to the power source of the monitor, trying different outlets in my house it still didn't work. I would appreciate the help troubleshooting this further and I'm able to give further info.
