Nvidia GTX1060 3GB & Gigabyte GA-970A-D3P MB; Bios screen doesn't show at boot

[videobruce]

I upgraded from a MSI AMD R7 260X that I had no trouble seeing the BIOS/UEFI screen during boot.
Now I can't, the screen goes dark until the O/S (Win7 Pro x64) loads.

My monitor is a Asus PA-248Q and I'm using the DisplayPort connection as I was before. The only change is the card. Using the VGA input thru an active DVI to VGA adapter, I do see the BIOS screen with that input.

I'm using the conventional BIOS setup, not UEFI if that matters which is what it has been. I made no changes other than the card.

Input needed.

is it simply not linking the card and monitor fast enough to catch the BIOS option when the PC POSTS?

Keep smashing the Del key as it boots and see if it catches it.

When he says 'smash', he means tap lightly every half a second

My monitor does that especially with DP, not sure why but if I need the bios I just tap Del or F2 repeatedly when it starts and it gets there eventually.

Frankly I liked the "smashing' part at this stage.

I disconnected the DVI/VGA cable, but no difference,
I tried some other cables (ports). 1st a DVI (for the heck of it) by itself and that was ok, the BIOS splash screen showed,
Then I tried another DisplayPort (15' instead of 9' that I was using). Still nothing,
The I tried a MonoPrice 6' cable that is a fraction of the diameter of the original cable and it worked. The BIOS splash screen shows. :banghead:

I'm guessing something between the MB, the video card and/or the monitor that isn't triggering activation of a video signal (for lack of a better term) until the O/S steps in. The Nvidia card is the #1 suspect being fussy for a unknown reason.

My question should be what would stop the the displaying of just the BIOS screen(s)? This surely isn't a HDCP deal.
