Eyefinity group displays and presets

I’m sure many are using eyefinity cards, I’ve had nightmares with groups not working when a display changes etc, and the presets not working, finally after much googling, I found the solution.
If you use standard mode, not advanced, when you save your preset, magically they work, if you use advanced they sometimes do, mostly, in my experience, they dont.
You can even change the preset while a patch is running but not full screen, so I now check the screen res, change the preset if necessary then go full screen from within the patch, which is great!
Hope this helps someone else too!

As an addendum, it seems the renderer as desktop, and screen resolution list doesn’t update after changing the resolution while v4 is running, which is a shame :(
