I'm not 100% sure on the details, but I believe the extra 8 lines are
overscan or other data (ie, not picture data).  I had the same issue
with the resolutions not being switched.  You need to update the
database to look for 1088 instead of 1080.  For example:

update `settings` set `data` = '1088' where  value = 'VidModeHeight0'
(or VidModeHeight1, etc)

Note that this has to be done via a direct sql update with 18.1, as
the setting GUI won't let you choose anything higher than 1080.
