Instead, at the panel side, you can tie the least bit of red to the most significant bit of red and do the same for blue, tie the least significant bit to the most significant bit. When you do this, it will ensure that you’ll get a full dynamic range from the very lowest to very highest value on each of those channels. Whereas with green, you are connecting 6-bits. All 6-bits get passed through on the green channel because green is considered the most visually important channel of the three.
