Must a CPU have a GPU if the motherboard provides a display port (when there isn’t any separate video card)

cpugpugraphics cardmotherboard

There is such a configuration: MSI A320M PRO-M2 V2 + AMD Ryzen 5 1400 BOX and there isn't any separate video card. When the PC is switched on, the monitor shows nothing. The MSI tech support said:

There is no GPU in the CPU Ryzen 5 1400, and the onboard VGA port cannot work with
this CPU. It is necessary to install a PCIe graphics card.

And added that

Whether it is Intel motherboard or AMD motherboard, the onboard integrated
GPU is in the CPU, not in motherboard. The motherboard only provides the
display port. There is no GPU in the Ryzen Summit Ridge CPU; only Raven
Ridge and Bristol Ridge CPUs support a GPU.

What I don't understand is that I have another configuration, ASRock 960GC-GS FX + AMD Phenom(tm) II X4 810. Again there is no separate video card. As I found out, AMD Phenom(tm) II X4 810 doesn't have any GPU. But the video works and this question I post using this configuration. How can this be explained?

Today, motherboard-integrated graphics are basically gone (in the consumer sector, anyway). It’s either CPU-integrated graphics or dedicated graphics. Both Intel and AMD still sell CPUs without integrated graphics, even with the same socket. If you install one of these, you won’t be able to use the display connectors on the motherboard.

In the past, CPUs did not have integrated graphics at all. Instead, the graphics unit was integrated with the motherboard (typically directly with the chipset). Your older Phenom II configuration comes from this time. It has motherboard-integrated graphics.
