I have a problem with video display in post and bios. If i connect my monitor to the discrete graphics card via displayport cable i don't see the post screen or bios screen if i press F2 during post. I know pc is posting because if i wait 20 sec windows shows up, and if i press f11 i can "blind" select partion to boot from. I have a second older monitor that i connect via dp to DVI converter and to the monitor and it always shows post and bios screen. Sometimes when i change where i plug my main monitor (graphics card has 3 dp ports)- post screen and bios screen works to first rebot or power off. I might add that this occurus for one or two months, and before that this issue didn't occured. Im not sure if it started after 4.20 to 4.30 update.

Aby solutions? Nie when i want to enter bios i have to unplug my new monitor and leave my ile monitor plugged to see post screen.
