    Reported Problem:

    Clean Install of latest Windows 10 Build displays no output to Laptop Screen but will output to external Monitor via HDMI Port or Display Port. Even with no monitors connected no display occurs to laptop screen. Booting to Safe Mode in Windows 10 does allow laptop screen to display with basic driver support.

    Clean Install of Windows 7 SP1 does display to Laptop Screen but upon installing the latest available software drivers from AMD laptop screen goes black and only displays to external monitor. Even with no monitors connected no display occurs to laptop screen after AMD Driver Install

    Reading online is recommended flashing GPU Firmware? Suggestions? Is there a way to get older AMD Drivers that I am overlooking?

    This laptop does not have any onboard video and requires both GPUs to be installed for screen output.

    Hi, and welcome to TSG,

    When you reinstalled the Win 7 AMD drivers did you get them from the support section of the Sager web site?

    I noticed they don't list a Windows 10 version of their drivers. I am not sure if their Windows 8 version would work in Windows 10

    One thing you could try in safe mode for either version of Windows, is to try to change the display resolution to match the native resolution of the laptop's LCD. I am thinking that the current data sent to the GPU for a normal Windows boot may not be compatible with the new drivers. Manually resetting them may get you the desired display and keep it that way on reboot.

    I suggest install the Windows 8 drivers in Windows 10 to try out. It couldn't hurt. I have installed Vista drivers in Windows 7 with no problems.

    I'm not sure if this will work, but you can try to remove the graphic cards and try to boot up.
