Detailed description:


I have a dual screen external setup.

One on USB C (through Display Port) and one on HDMI. Internal screen is off (PC closed)

At every statup or when the PC is waking up from sleep mode, the screen on USB-C is up, and the screen on HDMI is not detected.

I need to open Intel Graphics panel and click on detect, and after it's OK.

This setup was working with my old laptop from another manufacturer 🙄

Screens are also working well with desktop PC.

Thank you.


  • Hello pumpf6,

    If you only connect 1 monitor, and connect it to the HDMI,

    does this same issue happen?

    Also, please kindly check if your BIOS is updated.

    Thank you.
