Cant put Scale in 200%

Im new on manjaro and when I go to the settings → monitor and try to up the scale I see the msg: “Changes cannot be Applied, this could be to hardware limitations”.
Im trying to use two monitors [ my laptop and another] and I see that the second screen is wrong. I have a LG Widescreen 29" and the monitor that shows is a Lg 34".

I dont know if this error is because of the wront recognize of monitor or because of some problem with my graphic card. I have the dual GPU intel-nvidia and, yes, I try to follow the guides and as I see im using the non-proprietary drivers. But, I cant see some infos that shows in the guide in the nvidia-settings [ like refresh rate, resolution, etc.].

And the image:

From now on Im able to put the scale in 200% but i cant configure to 125 or something like that. My monitor is wrong defined in the system. I find a comand that appear to help with the scale but the font is a little bluer with it. The comand:
xrandr --output HDMI-1 --scale 0.90x0.90
