Can not detect external monitor via HDMI on Win 10

Pavilion 15-p288ng
Microsoft Windows 10 (64-bit)

Hello,

 

I have dual boot system with Ubuntu 19.04 and Windows 10. I have been using external monitor connected via HDMI for a while and it was all good. Suddenly I encountered issue with monitor detecting  - laptop can not detect it at all. When I connect it, it can not detect external monitor and on monitor only appears Power Saving Mode blue floating window and monitor goes to sleep. First, I had this problem on both OS - Ubuntu and Windows 10. Later, I have fixed it on Ubuntu, when I run Ubuntu with different options from Grub boot menu (I think I ran it with different kernel, but not sure), but on Windows 10 issue is still persistent. I have replaced different monitors and different HDMI cables, so this is not problem.

 

Any thoughts? Any help?

 

Best regards,

Aleksandar

Can not detect external monitor via HDMI on Win 10

UPDATE for Ubuntu 19.04

 

I had situation this morning where first it did not work with latest kernel 5.0.0-32-generic. I have installed older version 5.0.0-31-generic and it worked. After it I boot it with latest version 5.0.0-32-generic and it's working now. This is very strange.

After that, now it's working on Windows too.

 

I'm  really confused now.
