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". That would mean your width should be 263 mm, not 262 mm. -Doug -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
