I added some trimpots to my old projector for controlling the intensity of the individual colors (really just needed it for overpowered blue but added to all modules anyway. I thought 10 KOhm was a good one to go with for a 5V ilda signal but at the lowest position of the trimpot the module still outputs some 50mW power (from 300). Am I using the wrong resistance trimpot?
Or does this have to do with bad module driver bias or something?
The trimpot is connected to the R, G or B + signal cable.
