1280 and 854 are nearly relatively prime; I doubt you'll be able to
reproduce the problem on your screen.  The problem is not a 1px border
on one or the other edge, the problem is a 1px border on _both_
edges.  Indeed,
  (854/801)*1200 = 1279.400749063670412
which is correctly rounded to to 1279, so the behaviour you report is
correct.

Peace,
