ADL screen size won't go higher

Hello! I'm trying to set the -screensize to test my app. But somehow the height won't go higher than 1047

I tried all this options:

::set SCREEN_SIZE=iPhoneRetina

::set SCREEN_SIZE=iPhone5Retina

::set SCREEN_SIZE=640x1096:750x1334

set SCREEN_SIZE=640x1096:1242x2208

::set SCREEN_SIZE=iPad

The width is usually fine but the height can't be heigher than 1047.. Actually I noticed that if try to set the width too large, it will be limited, and the dimensions will look similar to my monitor width and height (although a little bit of the adl screen bleeds the monitor). Is the adl screen somehow limited by my monitor width and height? Can I change it so it follows the size i set?

I really really need to test it on the exact same dimensions i'm setting on -screensize (it doesn't matter if I won't be able to see a portion of it).
