You can always get a tv arm that fully articulates to mount them. They are strong enough to hold a 65" + OLED.
That's how I mounted my 43" Aorus display to the wall and used regular gas strut monitor arms for the smaller ones.
That's what I do for my 43" 4k as well, but my 43" has proper TV-sized VESA mount pattern (200x200mm).
The G9 49" has the standard monitor-sized VESA mounting holes (100x100mm) which is less common on heavier TVs and so some TV mounts might not have 100x100mm mounting options.
Pic related, this random wall mount from monoprice, it's large enough for the 49" display easily, but it only has 200x400mm to 700x500mm VESA pattern support.
That being said, if you shop around, it's easy enough to find one with 100x100mm pattern support.
pic related, supports 100x100mm up to 400x400mm
