I have 16 panels that were supposed to be a 4x4 matrix
3 of them seem to be at least 25% brighter than the others.

They were ordered from the same vendor in batches of 13 and 4 only 15 days apart.
The model and even manufacturing date are all identical.

Has anyone experienced any thing like this before?

How are you testing. If in a 4X4 array....have you tried changing a Bright with a Not-so-Bright. Does the Bright move with the panel?

Problem solved.
It was two bad data cables between panels.
Luckily I had 7 extras. Just swapped them once I knew the real problem.

I checked the cable and pin 15 labeled OE was open on both.
I am guessing that one is kind of important.
