E-readers make terrible second monitors, and that's exactly why I use one for work

Using an e-reader as a second PC monitor sounds counterintuitive, but the slow refresh rate and lack of backlight on ePaper displays can actually help you stay focused and reduce eye strain. The author uses a Boox Go 10.3 (Android-based e-reader) with an app called SpaceDesk to extend their laptop display wirelessly or via USB-C. While the setup works, it requires some research since most e-readers aren't designed for this use case. The author wishes dedicated E Ink PC monitors were more widely available and affordable — current options from brands like Bigme or Boox's Mira lineup are scarce and priced above $1,500.
