I really appreciate the info! However, I think most of the issues you encountered would've already been lessened by even the original Viture one, and the Viture PRO is even better than that, supposedly. Things like edge fuzziness are supposedly completely gone now with the pro version, which also improves upon the One in every category. Basically those xreal ones were "gen 1" and the viture pro is considered "gen 2".
Yes, 600 or so is expensive, but that's the cost of two plain monitors or one gamer/quality one. Considering how mobile and flexible it is, and the fact that it could replace several monitors while seeming to be large than all, I really don't mind the cost.
Edit: almost forgot, what's your glasses prescription (if that's okay to ask that is). I need to get mine updated, but I recall my main issue (and the reason I can't use 3D at all) is because my eyes are different prescriptions and don't even focus at the same rate. Thanks again!
