Hi I just came across this problem after disconnecting everything from my computer for cleaning purpose.
after reconnecting everything back the boot sequence and bios screen is cloned on both of my monitors while previously it used to show only on my main one and the second one remained dark.
how can I get it back to the way it was?
both my monitors are currently plugged into my AMD Radeon HD 7950 one into the HDMI port and the second into the DVI port. I'm not sure though if my secondary monitor used to be connected straight to my motherboard DVI port or not... I am assuming not because the secondary monitor doesn't display anything when connected straight to the motherboard.
this is triggering my OCD and is making me crazy please help me.
