When you connected your LCD, your display numbering probably changed too, so you should have adjusted GM for the new situation (e.g., -screen \\.\DISPLAY2). You shouldn't have messed with EDID emulation nor modelines.
However, since you redid the setup, VMMaker restarted your video card, that's where the odd display number 7 comes from. Restart your pc and the number will come back to normal. Always make sure you are pointing to the right video card output when installing the modes (video card tab).
