CFA633 brightness

We have a number of 1U chassis using the CFA633 and noticed that there seems to be brightness variance in the background.
We have implemented s/w to set the brightness and have found that, even with two (2) chassis using the same CFA633 part,
with the same s/w brightness setting, there is considerable variation in the brightness between two (2) chassis.

We are using command: 14 or 0xe, setting the level to 30 using 1 byte


When our customers initially reported the issue, we assumed it was due to different chassis containing different Crystalfontz
parts. Our earlier units used the CFA533. As noted above, we were surprised to find variance among CFA633 parts.
