Has the high-dpi external screens market just died? I haven’t really seen anything that can match iMacs except for the 2 LG Ultrafine that were recently pulled from the Apple store.
Very nice form factor but the DPI is just not there for me. At this resolution and screen size we're talking merely 140PPI. I refuse to work on anything below 200 with 250+ being more in the tolerable range. Fuzzy text bothers me a lot (and no, subpixel aliasing is not the answer to this).
An interesting form factor, but these days, anything that makes me adopt a different posture carries the risk of causing neck or back problems, and it might be difficult to evaluate this risk without buying the monitor in the first place.
