Hello, I am using a HP G60 Laptop and a Dell E176FP monitor. At first when I plugged in the dell monitor into my laptop, the same thing showed on both screens as in the same desktop and everything. But I did something with the display settings and now it just either extends the desktop onto the other monitor or doesn't show anything at all. I am trying to have the same thing show on both. How can I fix this? My laptop is running on Windows Vista Home. Thanks.
