  FYI: I'd pay to cover costs if there was a just-works off-the-shelf version of this. I don't think there's a business model there (I suspect the sales would be in the thousands or tens of thousands of dollars -- so no matter where you set your profit margin, you're not covering your time or much beyond costs), but I've sometimes seen things done like that on hobby projects just for impact. I'd love to have a wireless eInk display for my computer, ideally from a USB-C dongle (so it gets video and power), but HDMI + USB power would be fine too.

      That looks very nice. The $1800 version is exactly what I'd love to have as an extra monitor on my main computer, if not for the price tag. 3200x1800. 25.3". It looks really good. Unfortunately, as is, it's a little outside of my wallet range. There's a smaller $800 version too. 1650x2200. 13.3". That looks more usable. To me, a major upside of the OkMonitor is the wireless connectivity. That's very, very nice. Especially if the computer dongle could be made small enough for use with my laptop while traveling, it would be a very nice solution.
