Question Can't enter in BIOS

[Ludantes]

Hello,
I'm able to use Windows 10 but I can't go in BIOS or device boot selector
I use a Asus Z87-A with i5-4670K

This is what I tried:
-Change the pin position for 10 secondes
-Get the motherboard tiny battery off for more than an hour
-Disconnect my graphic card and every device but mouse and keyboard and use mobo HDMI
-Press the CLEAR button on mobo
Every times when I push F2 or DEL or F8 I get a black screen

For lord sake, what should I do ??
I still can play games and even overclock through software like Ai suite or Intel extreme utility
Oh yeah, I saw a lot of people using windows 10 to go to BIOS through advanced boot option, but when I do it I don't have the UEFI firmware option !

What GPU are you using? What monitor/resolution? How are you connected (HDMI, DP etc)?

I've seen situations where GPUs (760, 770 and a 950, specifically) won't display the BIOS over DisplayPort, only over HDMi. I've seen it be a pretty consistent 'blank' with a 1440p panel, but have also seen it with one 1080p panel too.

tl:dr, if using DisplayPort, try using HDMI.

Thank you for your reply, I use a 1080 as GC with HDMI
I used to go in BIOS a lot of times, and I didn't switch any video port
