Indeed, the only difference seems to be the stand and the immediate availability of the Auria EQ276W vs. the pending availability of the Nixeus NX-VUE27,…along with the slight price difference.
The Auria EQ276W stand will swivel but has no height adjustments. I’m not sure if the price difference is ~$50 or ~$30 now. Still if I didn’t like the stand I would buy a single, dual or triple monitor stand. Therefore the price difference isn’t worth it to me as I typically expect not to be impressed with the built in stand.
Decent height adjustable stands start at under ~$30 off of Amazon or the like.
BTW, you can see the back of both models here:

The first link is the Auria EQ276W and the second is the Nixeus NX-VUE27. You can tell that they are essentially the same save for the stand. However, it is unclear to me if the height adjustable stand of the Nixeus NX-VUE27 will allow you to tilt the display much without hitting the length of the stand (if adjusted lower). So the range of movement may be limited.
