Hi,

I have a TrueNAS system build around a Gigabyte Z490I AORUS ULTRA motherboard. Everything was working fine when the MB was paired with a Pentium Gold G6400 CPU.
However, after upgrading the CPU to an i7-11700, none of the video output ports are working anymore - there is no signal from the IGD on either HDMI or DisplayPort. Otherwise, the CPU works as expected and the display adapter is detected by the OS.

The BIOS is the latest version and has the display adapter set to Auto. There are no beeps during POST.

My feeling is that there's a compatiblility issue between the current BIOS version and the i7-11700 CPU. Is it possible to have a working CPU with a faulty IGD? Could there be something that I've missed?

Needs BIOS version F20D I would install the old processor to ensure that is your version.

My next thought would be that you mistakenly got a 11700F that has no built in graphics.

the display adapter is detected by the OS.

^^^^^ how would know this without a display?

Is there by chance a gpu in the system at all?

Another thought if your using a video card and trying to use the built in graphics on the motherboard at the same time, not sure if that can be done on that board they could be a setting in BIOS>

Usually if you use a card and the display is set to auto it defaults to the video card.

The CPU is NOT the F version (product code is BX8070811700). I can confirm that the IGD is at least visible to the OS as I can select it for VM passthrough.
The BIOS version is F21, published 2021/11/25. I don't have a PCIe video card installed.
 
Could be a lack of information since this was also stated.

the display adapter is detected by the OS.

Display adapter can mean so many things.... And I don't know you have TeamViewer installed and viewing the screen remotely like I do when I have these issue.... If you are meaning that you gave display through a graphics card state that not display adapter. I'm not the only one who was confused by that... You can't use dual display on this mobo after the third bios update they removed the option for dual display through gpu and on board.... This is becoming more common as the newer GPUs are being released with allto many display option to begging with there is no need for the on board and gpu.... It's also conserving the stress put on the system trying to display using the apu/CPU power, plus gpu.... Because of cou having to process the info from both, now it only has to read one display output
