I needed to constantly move and tilt my head so much it hurt. My specimen also had some problems with blurriness, I couldn't quite put a finger on what it was exactly, just it was definitely harder reading things on it compared to my previous setup, but this could be just an isolated manufacturing defect. Got rid of it and went back to two 27" monitors: one primary straight in front of me where all the work happens, I don't have to move head while working on it. One secondary for less important side things. Both are 4K and so in total I have way more resolution this way than with a single ultrawide. Very happy with this setup.
