Hi,

HP Omen 17 ck-1440nw

Windows 11

I have external display which was working fine for about 2 weeks.

Yesterday It stopped getting video signal via USB C port.

Tested on different laptop - It's OK.

Different display via USB C - also not working.

 

I did:

- CMOS reset

- BIOS / Tunderbolt drivers re-install

- Crtl+win+shift+B? (display driver reset)

 

Any ideas how to deal with it?
