Whenever I power on my PC, I get no signal until the windows 10 login.
I have 2 monitors, 1 HDMI and 1 DP. If i just have the HDMI monitor plugged in, the POST screen shows; if I have the DP monitor plugged in, it does not display.
I have tried so much:
Disabling / enabling / configuring CSM
Installed the DP firmware update for NVIDIA cards: https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/
Changing which ports I use for the monitors.
Changing my PC from legacy to UEFI
Resetting my MoBo's BIOS
I'm planning on dual booting Win
