Input not Supported please help

[chi_chi_]

So I changed something in bios, called something like "Ultra fast boot time" and now my monitor when I boot up the computer just says "Input not Supported."

I have a:

ryzen 5 1600

asrock b450 steel legend

16gb vengeance lpx ram corsair

rx 590 sapphire

vengeance 650w 80+ silver corsair

fractal design meshify c white.

I can't even get into bios now to put it back to normal.

Edit: I can't even get into sign in, bios, windows, i just turn on the monitor and it says input not supported.
