@linuxfanche Interesting product. Technically it would only work in very limited devices and won't work as intended. So short answer no, long answer, maybe

For wireless connection to work, it should be Miracast and currently compatibility is a hit and miss. Never found one that works on any of my devices.
If ever it would work, input lag would likely be bad
If it works well, I don't think Miracast support external touchscreen so you won't be able to control your UT device using the e-ink.
For wired, only a few supports it. Top of my head - Nexus 5, Nexus 7 2013, Shift phone, Fxtec Pro1 (Not Pro1-X), Fairphone 4.
Then not sure if those supports external touchscreen. Most likely, Nexus device don't. I can only confirm Fairphone 4.
Even with everything working fine, UT uses an external display as an extended screen and there's currently no mirror mode. Also, external touchscreen isn't working well because it is mapped to the device instead of the external display.
