Second Monitor says out of range
I hooked up a second monitor to my Dell laptop. It worked great when i first connected them i could multitask with them. Now my second monitor (Hp w2007) Says "input signal out of range" and to change it to the recommended settings, but it is on the recommended settings. Plus, the way that windows is displayed on the second monitor is clearly not right. it doesn't even fill the whole screen. I've tried other resolutions. The only time the monitor works while on recommend settings. The message saying it's out of range ain't there, and it fills the whole screen and looks great is when i select the option to show only 2. Can anyone help me with this?
