Dual monitor resolution question

Hello all,

I did a quick search on this and didnt find what i was looking for, so here i am asking for help.

I have a GUI which gets scaled based on the resolution of the current computer.

IE: $GUI = GUICreate("Test", @DesktopWidth / 1.5, @DesktopHeight / 1.5, @DesktopWidth / 6, @DesktopHeight / 6)

Now this works just fine when you only have 1 monitor. However, if you have 2 or more monitors, it will spread the GUI across all the monitors and it looks stretched and dumb.

Is there a way to make it only use 1 monitor even if you have multiple monitors?

Thank you for any help.
