MP4 look great on House Preview but washed out / low contrast on the lights

[gary@mansperger.ws]

I hope this is an ok place for this post!
I have 2 panels of 16 strings (5 meters, 150 pix) each on A frame roof . I can program the left, right, or both. The size and aspect ratio when I put up an MP4 is about right. Each of the panels is 10 feet wide by 15 ft high and the strings are about 7.5 inches apart (so when I program them as one display they end up about 20 ft long and 15 ft high.

Now when i put effect on them from Xlights all is good. But when I put an MP4 on them everything is washed out and the colors do not stand out. It looks great on the House Preview in Xlights.

Are there some settings that I can adjust to get better picture quality?? (I know I am stuck with the resolution, just trying to get the colors better. I have the same issue with gifs but not as bad.
Thanks,
Gary

Don't know if it matters but driving them with HinksPix Pro controler with a 16 SPI in the controller box for the first panel and a second box with a smart long range 16 SPI for the second panel

In general, you need to set the brightness down to about 40-50% maximum and then set the gamma to around 2.2-2.6.

That sound exactly what I am needing!
Is this done in Layout - Dimming Curves ?
Also is this for only one sequence or does it effect all sequences?

Thanks!!!

In general, those are better set at the controller level.   How are you configuring your controller?   If using the upload from xLights, then for the model, go down to the controller properties and click the gamma and brightness settings to enable setting them and adjust the value.  Then re-upload the outputs to the controller.

If manually configuring the controller, you would have to figure out how to set those in the controller's config pages.
