I have an Aspire 5250-Bz455 laptop...I am trying to get it to output to an external LCD monitor. I have tried 3 separate monitors using the VGA connection. (FYI, this is the first time ever trying to do this so it has never worked since I have owned it - the laptop is in mint condition and only used a few times).
I am running Windows 7 64bit - Windows detects each monitor and I can set it to extend the desktop or duplicate but no matter what I do, the monitors all say "no signal".
So Windows detects the monitor is connected but the monitor does not detect the computer is connected. All monitors are HD and fairly new. I have tried the Function key - the laptop screen blanks out for a moment...also tried Windows+P and those options do not work either. I have another laptop (Dell) that works fine with the monitors using the same OS and same settings.
I have tried to change the resolution, checked refresh rate, etc. I have completely uninstalled and removed all ATI drivers and software then reinstalled the latest version from ATI's web site - no change at all. Even with the laptop lid closed, "no signal". I have also tried 2 different VGA cables and they both work with my other laptop so its not the vga cable and its not the monitor.
Any suggestions would be helpful - please read what I have tried and don't repeat those steps if possible. Thanks.
