ACER NITRO 515-53 HDMI Display Doesn't work in Ubuntu 19.04

ROG3RBOT

I Installed the Ubuntu 19.04 distro in my Acer Nitro, but actually the second monitor plugged to the HDMI port doesn't appears to work, in the Display Administration the second display it's not present. But in Windows the second monitor works well.

Good afternoon ROG3RBOT !

Perform the procedures in the order:
1- Connect the HDMi cable to the notebook and monitor;
2- Restart the device or the GUI via the command line;
3- Access system-settings >> hardware and change "audio / video output" to HDMi
4- Change the video settings to "mirrored" and sound settings for HDMi

Do the test!

Have you tried another cable?
Checked the updates:
Configure your source with the latest repositories and give a sudo apt-get update and then sudo apt-get upgrade
Have you switched between the dedicated GPU and the integrated GPU to see if the image is being uploaded?
Connect the cable and do the following:
Give a terminal xrandr and copy the return output here.
