External monitor not connected

I recently installed Ubuntu 18.04 into my laptop along with windows 10. Unfortunately, my external monitor which is connected into HDMI-1 is not working on Ubuntu (Not detected). I tried almost everything here and here. It is connected with HDMI-to-VGA_Adapter. My graphics card is GeForce GTX 1650 and I tried to download this drivers from NVidia. Also, as you can see in the picture, on screen display settings it's not even show the screen layout.

On Ubuntu 14.04 (my old laptop) I had solved similar problem in the past by using something like:

echo $myNewMode
## Output: "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync
xrandr --addmode eDP-1 $myNewModeName
xrandr --output eDP-1 --mode $myNewModeName --output HDMI-1 --auto --right-of eDP-1

But, this didn't work either. Any ideas ?
