My PG349Q works with aurasync set from Armoury Crate. BUT if I want to create a theme with aura creator, my monitor doesn't show in the list. So the lighting I create doesn't apply to monitor but does in everywhere else. I think it's a big design failure from Asus. What if unsupported component would be for example a keyuboard. Nice to write without lighting...
It's not a surprise that you have issues with mixed setups, but my setup is all Asus (GA35DX, Gladius III wireless, Claymore II, H3 TUF Gaming and this display. And even my deskmat is Asus!), so it's really pity that Asus softwares work so badly even in all Asus setup which is probably the easiest setup in driver-wise. Money spent almost 8000 euros, and still the weakest link in setup is Armoury Crate which is btw the only way to install keyboard and mouse drivers, so I cannot even get rid of it if I wanted to.
