Whole set up with APA102 stripes and Hyperion NG Alpha 9 working perfectly with internal and external grabber in regadrs of changing colors. But as I want it to be perfect, I have a issue which I couldn´t find in the forum. When a dark scence comes up or the color is not in full brigthness (I would guess below 20-30% brightness), the led starts flickering but not hard flickering it like on off and it is happening with same the color. So it is not a black problem. This applys only to the external grabber. Which value need to be changed to stop that?
GND is connected to PI and Stripe.
This kind of flickering wasn´t visible with the old Hyperion. So guessing it is a Software option
I am asking, before I start to buy a new powersupply and ferrite filter.

I think I am getting the same issue. I did not find the right configuration. I think the issue is around "Color Calibration" in "Image Processing". For example I put "Backlight threshold" to "40%" this flickering effect disappear. But the light is on instead of black.

Actually right now I put all Gamma to 2.5 and deleted the the previous "Backlight threshold". I have now no flickering and the leds are black when black background.

Yes for black I did the same, because I had the same what you have said. But I have the flickering with the colored LED´s on low brigthness. But I think it is the Hardware. When I look into the Live View, I can see this flickering as well. I am thinking about to buy new hardware, as mine is Hdmi splitter and analog stick.

How many total LEDs do you have and what power supply?
I have the APA102 LED's and I've never experienced flickering. What baudrate and refreshrate do you have set on the LED Controller section?

It was the Grabber and Converter, don´t know which one has make the problems. Bought yesterday a new HDMI2USB Grabber, everything now works fine.
