Are you sure that youre VGA cable is connected to the graphic card. If it isn't it won't work.
So i recently decided since i spend most of my time on my pc and barely watch tv at all that i should connect the tv as my second monitor. I bought a VGA cable since the tv doesnt support HDMI or DVI. The first monitor was always connected with a HDMI cable and is working perfectly fine but the second monitor doesnt work at all. It says "check signal" or something like that so i thought i should look up a video on youtube to help me out, watched every single result, tried everything, still no progress. Hope someonr can help me out, if you need more info ill be glad to tell you.
