LSX Basic RGB Linearity adjustments

[lasermaster1977]

I've been trying to tweak my RGB linearity in LSX Basic and I don't see that changes have any effect. My projector has analog intensity control, so maybe I'm doing something wrong. I haven't been able to determine what is required, unless it is having LSX Pro.

Any ideas?

are you using this control?

Yes, that's the control I'm using, now it is working. I probably wasn't holding my mouth right.

yeah. try using your mouse instead of your mouth.

Note that when you are displaying a test frame for RGB levels (i.e. the grey scale test frame) the default brightness should be turned up to its max brightness assuming that it is safe to do so.

As for the actual setting aspect, for at least the lower power diodes, you will likely want to add nodes so that you can get a quicker jump on the low modulation end. This will help you match up low end response among your RGB diodes.

Thanks for the reminder David. I've added more adjusting nodes but hadn't checked everything using the gray scale test frame.

Great suggestion swami, and with the mouse it greatly reduces the amount of saliva gunking up everything.
