Hi, Actually these values worked for me, please have a look at the snap. I did connect grabber without splitter and it is working. Just a Red colour is little overtaking but 95% is fine. Pink and orange is more Red(ish) now.

Hi AmbientEric I did achieve the right reds and greens LED. Could it be the bad grabber?(I am using micro USB to USB 2.0 cable in 3.0 port of grabber from pi.) or could be something on HW side. I do not see any issue with HW side. LEDs are both powered and grounded from both end.

Hi pclin I tried that too. Yes, I am using 4k capture card.

Ambient_theater77 I checked for HDR, it is not for HDR.

Here is the picture, may be you can get idea. You can see the colours. (Specially looking at Apple Music logo and YouTube logo.)

Hi pclin,

Much appreciate your response.

I tried that, but not working for me. However, I discovered that my input of video is reading not correct. When I opened my live video wizard, which is reading wrong and I get the out put same as that wizard. So I think my problem is at the input level, where initial input is not right.

I am using 4k 60Hz capture card. Source is my ps5. And I am using USB 2.0 to microUSB to my pi.

Thanks,

Regards,

Dhaval

Hello guys,

Appreciate your knowledge regarding sk6812spi.

I have setup all HW and SW, but not getting correct LED output as a result. All LED reacts though, but not in order as it suppose to. I am not able to setup RGB order, none of the option works for my setup. Any idea why it is happening?

Any guidance will be appreciated.
