Lightboost 0% (off)....

[Falkentyne]

Why exactly does lightboost 0% remove the purple tint but raise the persistence to the same as lightboost 100%?
Yet set LB to 10% and the purple tint instantly appears (past a certain contrast) and the persistence instantly drops to 1.4 or 1.8ms.

What's going on here? What is lightboost 0% for if the monitor is still using lightboost (storbing?)

which monitor?

[Falkentyne]

Any monitor. Asus VG248QE, Benq Z, Benq T, every monitor with lightboost.
(BTW it doesnt' really remove all of the purple tint...just 'some', but I want to know why it looks like visually its at max (lightboost 100% persistence) which is either 3 or 2.5ms (100hz or 120hz) but the screen is identical darkness like lightboost 10%

The strobe length is as long as 100% but with less voltage (shorter peak).
TFTCentral has some oscilloscope measurements of LightBoost 0%

I have no idea of the purple tint issue, but I have one wild guess -- it might be the longer/shorter strobe lengths affects different phases of LCD inversion, which may be greenish or purplish if the strobing occurs at a different phase of LCD inversion -- see http://www.testufo.com/inversion for examples of the color distortions that occur (even in non-LightBoost mode). But it may also be the color calibration of the LCD itself that has changed during 0% versus 100%. It would be interesting to have a specific technical explanation.
