i have the following problem:
My Ambilight shows the colors only on the left bottom and bottom side of the TV. It shows the colors from the top on the left bottom and the colors from top right on the bottom side.
The Top,Right side dont light up.
Hardware Setup: RPi Zero + WS2812b + Hdmi Splitter + Hdmi to AV + Hdmi Grabber (stk1160 chipset)
I have grounded every hardware component. I connected the GND of the Leds to the GND of the Zero and the Datapin to GPIO 18 (Pin 12).
I have 202 Leds: 65 at Top/Bottom + 36 Left/Right
The First Led is on the bottom right (if viewed from the front of the TV).
This is exactly how the LEDs are lined up. As you can see i can also grab a Screenshot from the hdmi grabber.
Only Leds from 67 - 91 and 40 - 50 light up after starting Hyperion.
Software Setup: Rasbian Buster on the Pi with Hyperion installed
The Weird part ist, that using the Hyperion App, i can connect to the Server, set Effects and set colors using the colorwheel.. All Leds light up and react correctly when using the App.
My thoughtprocess is that i already have the Imagedata from the Grabber (i can grab a Screenshot) so it has to do something with the config thats wrong? Or could it still be a Hardware problem like the grabber not delivering the signal fast enough or the hdmiToAV not working properly?
I would love to know whether the config is correct..
I am out of ideas and i hope one of you guys could help me out debug this..
