Integrated graphics (iGPU) not working

[ravv4]

I have an i7-14700K and when I set multi-monitor (iGPU) in the BIOS - it does not work, ie. 'Intel 770' does not appear in Device Manager.

I have a replacement CPU as it was happening with the old one too.

Not sure how to get this working?

Hello ravv4,

To assist you effectively and resolve your issue, I need some additional information. Kindly provide answers to the following questions: 

• What operating system are you using? Is it up to date?
• What is the make and model of your motherboard?
• Have you installed the latest Intel graphics drivers for your iGPU?
• Are your monitors connected to the motherboard’s video outputs (e.g., HDMI, DisplayPort), not the discrete GPU ports?
• Did you save and exit the BIOS settings after enabling the integrated graphics?

Thank you for your cooperation.

Hi RandyT,

Hope the following info helps:

- Windows 11
- Asus Z790-A II motherboard
- Latest Intel graphics installed, but arc software shows error because iGPU not found.
- I have tried connecting straight to motherboard DisplayPort and HDMI but nothing displayed.
- I did press F10 to save BIOS after enabling iGPU.

I have just binned this motherboard and am getting a replacement. I think that the issue is that I had a Bitlocker crash on the boot drive and it corrupted the TPM. I am hoping that the new board along with a new SSD will enable me to install Windows again and be able to run a UEFI BIOS with iGPU enabled and working. I have a literally new CPU (i7-14700K) so it should all be working like this.

Hi ravv4,

Thanks for the update. Your plan sounds solid. Replacing the motherboard and SSD should address the Bitlocker crash and TPM corruption. With the new hardware, you should be able to install Windows, enable UEFI BIOS, and get the iGPU working. Given that your CPU is new, it should all come together seamlessly.

Keep me posted on your progress or if you run into any issues.
