Hi guys. recently installed Windows 7 64-bit on my laptop and so far everything's been working fine except for my second screen. When I plug it into the VGA slot, my main monitor flickers and adapts like it should to accomodate the second screen and windows detects the second screen but the latter wont switch on. I tried about 4 screens and they all dont receive a signal even though windows detects the screen. Can anyone help on this one?
