I have your X11SSZ-F motherboard and Intel i3-6100 CPU with HD graphics 530, I found DVI were not able to give any output. Is there any setting in BIOS that I need to change?
The default setting in BIOS is using onboard ASPEED 2400 VGA output, You need to do the following setting for DVI or display port.
In the BIOS >> Advanced >> ChipSet configuration >> System Agent configuration >> Graphics Configurations
Primary Display >> change to [IGFX], default was [PCI-E]
Internal Graphics >> change to [Enabled], default was [Auto]
