I'd like to add one but have no idea to do it
![Embarassed :oops:](./images/smilies/icon_redface.gif)
I've just bought 1k ohm potentiometer (this one https://www.ebay.fr/itm/173588627931?var=472269288262).
Do i need to add ground ?
==================
Another question please, i need to find RGB signal position, i found :
R407 for RED
R420 for GREEN (JF Del Nero picture, thx)
R432 for BLUE
Is someone can confirm Red and Blue motherboard signal position ?
