I note that your LEDs are laid out with overlap in one axis but none
in the other. I suggest that you need to have all neighbouring LEDs
overlap the same amount to obtain a more even coverage. With your
'offset row' layout each LED has 6 neighbours to overlap with.(4 on
the edges)
All the best with the fine tuning.
