Nostalrius Begins - Quality wow vanilla realm (1.12)

When I start my client, WoW always starts on monitor 1 (main/default monitor with my taskbar).

In 'modern' WoW there is a option to show the window on monitor 2 but in classic this option doesn't exist.
So how can I do it?
You guys got any advise or experience with this?

Window mode.

Yeah I run it in window mode and/or maximized window mode.
But everytime I start the Game the window displays at monitor 1 and not 2.

Config.wtf file lines you'll want:

SET gxMonitor "1"

or 2 for that matter, I am not sure if vanilla support this code or not, try it out.

'Shift + Windows key + Left or Right arrow' changes standard monitor for fullscreen, might work for you. Try it out.
