Terminal Emulator not working

My commands on Terminal Emulator do not work. I've already tried to change de dpi (wm density) and screen resolution (wm size) and nothing happens.

Here's what it shows.

Could there be something to do with 'Busybox on rails'? 'Busybox'? 'Build.prop Editor'?

Is there any other way to change the screen resolution?

Thanks.

(PS: Android MM 6.0)
(PS2:Yes, I'm rooted. Yes, I typed "su". Yes, I tried multiple emulators)
