See specs in the link above. Bought in September 2024, normal household usage, all functional. Display is all good (as far as I know there's no dead spot).
I've been using a clamp & arm vesa mount with the screen, so its original mount is new in the wraps (see pic). $300 is screen + the original mount. The arm mount is https://newjersey.craigslist.org/sys/d/cliffside-park-ergotron-vesa-mount-for/7882378353.html , $50 if bought along with the screen.
