I have two non-functioning HDMI ports on the back of my computer. When I plug an HDMI into one of the ports, there is absolutely no signal and this is confirmed by trying to switch the input on my monitor to HDMI.

I have attached an image of the back of my computer so that you can see for yourself which ports are non-functioning and which are functioning properly.

The two HDMI Ports circled on the bottom right are non-functioning, while the DisplayPort and HDMI ports circled on the top left are functioning.

I know that the two ports on the bottom right are not connected to the graphics card, but I guess I'm just confused as to why there would be two HDMI ports that are unusable.

If there is any troubleshooting I can do to get these working, please let me know.

All help is greatly appreciated!

t53186 is correct.

The integrated graphics chip is dissabled by default whenever you have a dedicated GPU inserted.
On most intel systems, you can go in and change the BIOS in order to allow both to be active.

Now on some systems it gets a little more complicated.
Many motherboards are made to support a wide range of CPUs, this can mean that the motherboard has video ports but the CPU is completely lacking integrated GPU chips.
For example I have a Ryzen 1700 cpu and ASUS B350-F motherboard. Asus designed the board to support the upcoming 14nm APUs that will be coming out and thus put video output ports on the board. Since my Ryzen 1700 cpu does not have an integrated graphics chip then these ports will never be usable with my...

The two ports on the bottom right are integrated in the motherboard and if your cpu supports graphics (embedded) you could go into bios and set the integrated graphics as active and the motherboard ports would work. Basically you could have that computer built without a graphics card and still use onboard (embedded) graphics.

Thanks for your responses guys. I have researched a bit about my CPU to see if it has the integrated graphics chip and I do believe that it does, however I wanted to post my specs here to see if anyone knows for sure.

Windows 10
CPU: 3.4 Ghz Intel Core i7 6700
RAM: 16 GB DDR3
GPU: NVIDIA GTX 1060 3GB GDDR5

Next step would be to edit the BIOS, which, I'm not going to lie concerns me to mess with. I am okay with computers but not great and I wouldn't want to mess anything up. Advice on that is also appreciated.

Thanks!

6700 does have integrated intel HD graphics.

You can certainly look online for instructions how to do it on your specific motherboard.

If you were to mess settings up in BIOS it is nothing to sweat as all motherboard have a simple procedure to reset it by swapping/shorting a jumper on the board. Just need to follow the procedure in the motherboard manual.
