To be clear, the motherboard only has outputs to pass through video signals from the CPU. The motherboard itself (at least over the last several generations) does not have onboard graphics, only ports to support the integrated GPU on the processor.Well that is how the motherboard documentation refers to it. The motherboard has onboard graphics, but the CPU does not, so that might be why the motherboard differentiates it. Not sure. It is not part of the motherboard, so it is something extended off the motherboard (aka in addition to). That was part of the original issue. I didn't realize that the motherboard and CPU had to have onboard graphics for the onboard graphics to work. I thought all of it was on the motherboard, so I thought I had onboard graphics, but some of the fine print in the motherboard information said "only with a A series CPU".
Sorry, as mentioned, I might not be using the right term, as mentioned before. Just quoting how the motherboard manual refers to it as (in 20 languages)
Most mainstream Intel CPUs have an igpu (except those they recently started selling without - they have an "F" in their name). None of the HEDT processors in the last few generations have an iGPU.
