I'm no expert on this subject, but when adjusting the Gain and Bias in my Sony LCD projector, the Gain seems to affect the brighter end of the grey scale and the Bias the lower. Perhaps someone more savvy on this will jump in here.
To be honest, I don't have a clue what you said means. Is Georgeb's non-technical explanation correct?
I guess I was wondering why JVC provides user adjustable Gain values, but not Bias ones. It appears that DILARD allows the adjustment of Bais. I was curious how useful that feature would be.
Milori can probably help here. My understanding is that Dilard provides bias control as an aid to calibration. It sets operatational points for the LCD panels, which affects the contrast ratio in D-ILAs. Yet, if you don't have a clue as to what bias is, I strongly recommend that you leave it alone, and send it to someone to have it calibrated.
