Not sure if here or in the showcase thread should be postet. This here is more only hardware facts. I am looking really hard for Hardware which would be the perfect solution. Problem here is, that here and there somebody posting it but there is no overview. Now to help newbies like me, it would be great to give them information which hardware runs fine. Feel free to add your equippment, this will help a lot of people. Let me start with mine setup: Raspberry: 3b+ Software: Alpha 9 Strips: APA102 to GPIO HDMI Grabber: Analog Grabber with 4k Converter (old setup); Platform: Retropie Informations/Problems: - I have flickering in dark scences which comes from the external equippment. Reduced it by setting Gamma to 3, but still slightly visible. Internal grabber works fine. - 4k Converter has Rainbow image, if no signal will be detected. Update: Bought a new grabber. This little guy solved all mentioned problems. But video resolution needs to lowered, otherwise the video will stutter so will the led.
