Screen is black until login screen

My monitor is quite old Nec p221w connected to Nvidia GTX780 trough DVI
I use Gnome

After upgrade my mobo cpu and ram I did fresh system installation.
Now I can’t go into bios. I can’t see grub info.
MY screen is black.
It’s not that no information is displayed. My monitor is on standby mode until gnome login screen.

I checked even older monitor.
17-inch Samsung. On this monitor. The same cable, same dvi on gpu everything is working fine. I can go into bios, can choose grub entries.
