X lists it as Unknown:

X.Org X Server 1.19.2
Release Date: 2017-03-02
<...>
[ 53523.905] (II) modeset(0): Output Unknown19-1 has no monitor section

[ 53523.912] (II) modeset(0): Output Unknown19-1 using initial mode
320x240 +0+0

Looking at the weston source it will list it as UNNAMED.

This is not important for me to change, I'm just ticking off todo's.
I won't chase down userspace to fix this up, but I assume that it will
trickle in eventually.

I can drop this if you're not to happy about it.
