pulled in changes of today:

screenshot on (1)
remarks:
1. the below and above are fixed, but i have 2 times left-of. which is
not very informative (so SAMSUNG 17 is left of DisplayPort-1 and ENC
24 is also left of DisplayPort-1)
2. SAMUNG 17 and ENC 24 are incorrectly labeled.
3. the 'Display indicator' on DisplayPort-1 is in the middle of the
screen (inconvenient but not deadly.)
