Monitor "blinks" when i turn on 2nd monitor

Hi. I have 2 monitors hooked up to my graphics card. My first monitor is a Acer 23' and my 2nd monitor is a vizio 19' which is also a tv. I usually just use my main monitor. However when i turn on my 2nd monitor to watch tv or have more desktop space, my first monitor "blinks" (turns black for a second and makes a sound). I was wondering what the problem is and how can i fix it?

This is my first monitor (acer)

This is my 2nd monitor (vizio)

This is my graphics card
