Hi,
I will explain my situation from the beginning..
My laptop before 2 months was working fine.. when i connect displayport to hdmi adapter to it then to the tv it will display just fine.. but after 3 weeks one usb port broke and cannot operate.. after I update the bios the usb port worked but the graphics card whatever I do with it (installing old/new drivers.. connect it directly to displayport monitor, even displayport to hdmi adapter) .. the graphics card drivers simply crashes and it will say: (Your PC can't project to another screen. Try reinstalling the driver or using another video card.)
even i went to acer's website I could not find the graphics drivers...
My model is : G9-791-78CE acer predator 17
i think the bios v1.10 is causing the issue .. any help??
