I can't connect an external display to my laptop with HDMI cable

[Dennis198]

Greetings...

I'm having trouble connecting an external display (HP 27es) to Laptop (HP Pavilion Gaming Laptop 15-dk0xxx) running Windows 11 via HDMI cable.

What I've already tried to do:

- change cable (doesn't work)

- change screen (I tried to connect the Laptop to the TV and it doesn't work...)

- change Laptop (I tried connecting another Laptop (with Windows 10) to the external screen and IT WORKS)

- change the input settings of the external display

- change the screen refresh rate

When I connect the external screen (HP 27es) to the Laptop (HP Pavilion Gaming Laptop 15-dk0xxx) the screen turns on and shows:

HDMI 1 inactive

HDMI 2 inactive

with a subsequent error message:

"Entry signal not found"

"Check the video cable and video source."

"Display sleeping" (and then turns off again)

However, if I connect the external screen and go to "Device Management" --> "Monitor" --> it appears:

- Generic Monitor (HP 27es)

- Integrated Monitor

so it means that the screen is recognized...

Furthermore, if I go to "Settings" --> "System" --> "Display" --> "Advanced display settings" and select the various displays I see some differences:

- if I select screen 1 "Internal screen", it tells me: connected to Intel(R) UHD Graphics 630

- if I select screen 2 "HP 27es", it tells me: connected to NVIDIA GeForce GTX 1650

I appreciate your commitment to service.

A thousand thanks
