In what way is the stand "too big"? I suspect it needs to be rather large, since that's a rather large screen, and you probably wouldn't want it tipping over.
The screen apparently has 100mm VESA mounting holes though, so a television stand along the lines of one of these would probably work...

I don't think they really feature much in the way of tilt adjustments, but that might not be a problem. Without knowing the dimensions of the X34's stand or how it gets in your way, I can't say whether this has a smaller footprint, but it only has a single leg, so the base should be a bit flatter, at the very least. There are other similar kinds of stands available on Amazon as well, though you'll want to make sure it's something that supports screens of that size.
