I have a new HP envy desktop computer. I need to have 2 monitors for it. I have one hooked up just fine. When I went to hook upi the other one, I used and adapter cord and the other monitor came on but then it would flash on and off (both Monitors) and then the icons would get small and hen say input not supported? Not sure what to do, seems like its something with a screen resolution but I tired to change that and nothing worked. Can someone please help?
