HDMI not getting detected

Hi!, I’ve been having a problem with my displays and xrandr. I’m running a fresh install of Manjaro xfce4 that i just installed yesterday, and it was working fine until i installed the optimus-manager and changed to only use the Nvidia card. It worked for some time but just today it decided to broke down and now my HDMI is not getting detected.

Any help would be appreciated!!.
