VGA monitor resolution stuck at 640x480

Hi everyone, since I installed Manjaro in my new PC I haven’t been able to change my second monitor’s resolution, the maximum resolution reported by Manjaro is 960x540, but when I look at what’s my monitor reporting it says 640x480, I have tried many ways to set a custom resolution in xrandr, but I always get this message:

$ xrandr --addmode VGA-0 1600x900_60.00
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  31
  Current serial number in output stream:  32

I have also tried other things, like Custom Screen Resolution, reinstalling Nvidia 390.xx drivers and arandr, with no success. I don’t know what else to do, I feel like I’ve tried everything.

Here’s what xrandr throws:
