Motherboard HDMI port not working

Good evening,

I have just installed a new monitor on my computer, and I just realized that the HDMI port on the motherboard is not working. When I plug the monitors into the graphics card, there’s no problem, but when I plug them into the motherboard ports, nothing happens. The issue is that I only have one port on the graphics card, and I can’t find a solution; I’ve tried troubleshooting with Windows but to no avail.

If someone could help me, please :)

Information about the PC:

Graphics card: 4070 ti

Processor: i7 12th gen

(Feel free to ask if you need more info)

Hello Blotox

with a CG on the MB => the HDMI port of the MB is disabled

Say, you don't have three DisplayPorts on your GPU ??????

Yes, I have 3 DP on the CG, but I would rather fix the problem than buy a converter

I suppose you understand that it's normal for you to have no image when you plug your monitor into the video outputs of your motherboard. When a dedicated graphics card is inserted, the BIOS disables the IGP (Integrated Graphics Processor in the CPU) to save resources. The video outputs of the motherboard, no longer connected to a video processor, cannot function. You still have the option to go into the BIOS to reactivate the IGP, but very few people do that. Furthermore, you did not specify the exact model of your CPU. Some models of the 12th generation CPUs do not have an IGP, such as the Intel Core i7 12700KF. If you put it on any motherboard, the video outputs of the motherboard will never work.
