Developers have been working on ways to use Onyx’s Android-based ereaders as secondary computer monitors.
A couple of videos have been uploaded to YouTube recently that show people using VNC to wirelessly mirror a computer’s display on an Onyx ereader.
The E Ink screen has some benefits as a secondary display, like being easily readable outside in direct sunlight, unlike LCD screens.
E Ink displays also come with some drawbacks, mainly the slow refresh rate and excessive flashing.
But if you like the idea of having an E Ink PC monitor at least there are ways to do it without having to spend a fortune on a device like the Dasung Paperlike, a 13.3-inch E Ink USB monitor.
Onyx is also working on an E Ink laptop so it looks like there could be a few different options for E Ink monitors this year.
Check the description at YouTube on the second video for more info.
