Earlier you said that the active area of this panel was:
Display area 262.656(H) X 164.16(V) (12.2”diagonal)
In other panels I looked at the EDID tended to round numbers, not
truncate them. For instance the Starry panel that I sent the patch
for says in the manual "262.7712 (H) x 164.232 (V)" but then the EDID
says "263 x 164".
Ah, got it, done.
Thanks,

That would mean your width should be 263 mm, not 262 mm.
