Full graphic Controller resistor?

Just purchased a full graphic 12864 controller board from AMazon. After ordering, I noticed the Vicious 1 version of this board (picture) has a resistor added to the back side of the board, which mine doesn’t have. Will I need to add this resistor to my board? Thanks for the advice!

Hopefully not, there are a bunch of bad ones out there with the wrong value resistor on them. That was needed to get the contrast right. Shouldn’t need it anymore, I need to get rid of that picture.

Thanks for the reply and feedback. Love your website and admire the impact and your contributions have made with this technology. Thanks for that too!

Thabks for that and your welcome!
