i won't bore everyone the details, but my experience with ASUS FM2+ motherboards including A88XM-A has been terrible, over the past few weeks.
i am running windows 8.1 with the latest amd drivers/catalyst (beta 14.1). i have the monitors plugged into vga and dvi. when the pc boots, both monitors show the same screen. then when windows is loaded, only the vga shows.
in the display properties only one monitor shows up. when i click detect, still only one monitor shows up.
how can i get dual monitors with extended desktop to work with this setup?!
